Ladies
and Gentlemen:

This
letter is submitted on behalf of AgeX Therapeutics, Inc. (the “Company”) in response to the comments of the staff
of the Division of Corporation Finance (the “Staff”) of the U.S. Securities and Exchange Commission (the “Commission”)
with respect to the Company’s Amendment No. 1 (“Amendment No. 1”) to Registration Statement on Form S-4/S-1
(File No: 333-275536) filed on January 16, 2024 (the “Registration Statement”), as set forth in the Staff’s
letter dated February 1, 2024 (the “Comment Letter”). The Company is concurrently submitting Amendment No. 2 to the
Registration Statement (“Amendment No. 2”), which includes changes to reflect responses to the Staff’s comments
and other updates.

For
reference purposes, the text of the Comment Letter (italicized) has been reproduced herein with responses below each numbered comment.
Unless otherwise indicated, page references in the descriptions of the Staff’s comments refer to the Registration Statement, and
page references in the responses refer to Amendment No. 2. All capitalized terms used and not otherwise defined herein shall have the

Amendment
No. 1 to Registration Statement on Form S-4 filed January 16, 2024

Page

    1.
    We
    note your response to our prior comment 1. Given that the NYSE American listing condition is waivable, please further revise your
    disclosure to indicate whether recirculation or resolicitation of shareholders will occur prior to the vote if the listing application
    is not approved but the condition is waived. If AgeX shareholders will not have certainty regarding the listing of the combined company’s
    shares at the time they are asked to vote, please clarify this fact. Please also provide risk factor disclosure that addresses the
    potential consequences of the parties waiving the condition and the closing occurring without the NYSE listing, including but not
    limited to the liquidity implications thereof.

RESPONSE:
The Company acknowledges the Staff’s comment and has revised the disclosure on page 6 of Amendment No. 2 to confirm that the
condition will not be waived.

Questions
and Answers about the Merger

Q:
Did the AgeX Board engage an independent financial advisor to shop AgeX or deliver a

fairness
opinion in connection with the Merger?, page 4

    2.
    We
    note your response to our prior comment 4 and reissue in part. Please revise your answer in this section to highlight that AgeX’s
    board did not value the companies in terms of absolute/dollar values.

RESPONSE:
The Company acknowledges the Staff’s comment and has revised the disclosure on pages 4 and 25 of Amendment No. 2 to highlight
that AgeX’s board did not value the companies in terms of absolute/dollar values.

Q:
What is Juvenescence’s relationship with AgeX?, page 5

    3.
    We
    note your response to our prior comment 3. Please further revise your disclosure to clarify the percentage of AgeX common stock Juvenescence
    will hold after the preferred stock conversion on February 1, 2024, in addition to disclosing that the conversion will “increase
    Juvenescence’s ownership and voting power to more than 50% of the outstanding shares of AgeX common stock.”

RESPONSE:
The Company acknowledges the Staff’s comment and has revised the disclosure on page 5 of Amendment No. 2 to clarify that after
the preferred stock conversion, Juvenescence’s ownership of the outstanding shares of AgeX common stock is approximately 80.59%.
Amendment No. 2 has been updated to reflect that the AgeX preferred stock conversion occurred on February 1, 2024.

Background
of the Merger, page 133

    4.
    We
    note your response to our prior comment 12 and reissue in part. Please revise your disclosure in reference to the October 21, 2022,
    entry to explain the potential drawbacks of valuing the companies in relation to their “relative values” rather than
    in terms of absolute valuations.

RESPONSE:
The Company acknowledges the Staff’s comment and has revised the disclosure on pages 4 and 25 of Amendment No. 2 to explain
the potential risks of valuing the companies in relation to their “relative values” rather than in terms of absolute valuations.

    5.
    We
    note your response to our prior comment 24 and reissue. Please disclose whether AgeX’s board conducted or considered any financial
    analyses that resulted in a valuation of either AgeX or Serina. In particular, discuss whether AgeX’s board conducted or considered
    a liquidation analysis or analysis of precedent reverse merger transactions. To the extent they were not conducted, explain why.

  Please address the following regarding the Serina Budget
Projections prepared by Serina management and reviewed by AgeX management and its advisors on page 155:

 ● Please
                                            expand your disclosure to discuss all material assumptions used to develop the projections
                                            that are not Total Additional Cash and Total Operating Expenses.

 ● Identify
                                            the counter party to the license agreement, the nature of activity, and specific contractual
                                            triggers for the receipt of the $3 million and $5 million from license agreements reflected
                                            here.

 ● Separately
                                            identify and quantify the amounts to be received here that are expected from Juvenescence
                                            or other related parties, identifying any contractual payment triggers and the extent to
                                            which they are optional versus mandatory.

 ● Address
                                            how the board evaluated and determined the reasonableness of the projections, the extent
                                            to which alternative scenarios were provided or considered, and the extent to which the probability
                                            of achieving such projections was assessed.

 ● Please
                                            also discuss the possible impact if the projections are not correct and clarify when all
                                            the projections were provided.

  Please address the following
  related to our prior comment 42:

 ● Revise
                                            to more clearly label the amounts presented in the “Warrants” columns on the
                                            tables on pages F-26 and F-56, and revise to quantify the total number of warrants outstanding.

 ● Explain
                                            why the subtotals of these columns do not foot, and explain what the subtotals actually represent
                                            and how they differ from the actual total number of warrants outstanding as of each balance
                                            sheet date presented.

 ● Revise
                                            the table to separately quantify any warrants exercised or expired during the periods presented.

    ●
  Given, among other things, the fair value per share assumptions
as provided on page F-55, the resultant fair values of each issuance as shown on page F-56 and the disclosure on page F-56 that none
of the issued warrants have been exercised, please explain to us and revise to disclose the underlying facts and circumstances that result
in your outstanding liability classified warrants having a fair value of zero as of September 30, 2023.

RESPONSE:
The Company acknowledges the Staff’s comment and has revised the disclosure on pages F-26 and F-56 of Amendment No. 2 to reflect
the Staff’s comment.

The
Company respectfully advises that the “Warrants” column on the tables on pages F-26 and F-56 reflects, with respect to
the initial measurement/origination date of February 14, 2022 and the period end date of December 31, 2022 (for the table on page F-26)
and the period end dates of December 31, 2022 and September 30, 2023 (for the table on page F-56), the number of warrants that would
have been issued if the full amount then available under the Secured Note had been drawn down at such origination date or period end
date, as applicable, and in each case calculating the number of shares underlying such warrants based on the market closing price of
AgeX common stock as of such dates. As a reminder for the Staff, the number of warrants to be issued is equal to 50% of the number determined
by dividing the amount of the applicable drawdown by the last closing price per share of AgeX common stock as reported on the NYSE American
on the date preceding delivery of the notice from AgeX requesting a draw down. In the case of the number of warrants on the origination
date and the applicable period end dates, the market closing price of AgeX common stock used for the calculation was as of such origination
date and period end dates, as applicable. With respect to applicable drawdown dates, the number of warrants issued upon such drawdown
was based on the market closing price of AgeX common stock on the date preceding delivery of the notice from AgeX requesting the drawdown,
in accordance with the terms of the Secured Note.

The
Company further advises that the estimated fair value of the warrants on the origination date (February 14, 2022) are recorded as a warrant
liability, and then, as funds are drawn, the warrant liability is adjusted for the estimated fair value of the actual number of warrants
issued in connection with the corresponding drawdowns under the credit facility. A similar approach was used for the remeasurement date(s).
For, example, as of December 31, 2022, the Company had drawn all except $500,000 of the applicable credit facility available to the Company,
and the 454,545 warrant shares represents the estimated number of warrants that could have been issued in connection with a final $500,000
drawdown on December 31, 2022. Accordingly, the final number of warrants in the “Warrants” column is not the sub-total of
all numbers in that column, but instead reflects the updated measurement of warrants as described above and as described in an updated
footnote 2 to the tables included on pages F-26 and F-56. The Company further respectfully advises that the “Fair Value per Share”
column in the tables on pages F-26 and F-56 appropriately do not foot and are not intended nor presented to be sub-totals.

The
Company further respectfully advises that none of such warrants have been exercised or have expired as of the date of Amendment No. 2,
and the Company has added disclosure in Amendment No. 2 to that effect.

    U.S. Securities and Exchange Commission

February 6, 2024

The
Company further respectfully advises that warrant liability exists only due to a potential future obligation to issue warrants and not
due to any terms of the warrants themselves that would trigger liability accounting, and, accordingly, warrant liability is zero once
there is no potential for future warrant issuances under the applicable credit facilities. The warrants issuable in connection with the
secured note for the $13,160,000 credit facility dated February 14, 2022 were issued in full by January 25, 2023 and the warrants issuable
in connection with the additional $2,000,000 credit made available under an amendment to the secured note dated February 9, 2023 were
issued in full by April 4, 2023. Accordingly, there are no further warrant liabilities outstanding thereafter, as is reflected in the
table on page F-56.

    We
    have reviewed your revision related to our prior comment 43. You state on page 325 that the net decrease of $0.2 million in research
    and development expenses for the nine months ended September 30, 2023 “was primarily attributable to reductions of $0.2 million
    in outside research and services allocable to research and development expenses.” Then, in the explanation of changes in research
    and development expenses for the year ended December 31, 2022 on page 327, you describe changes in expense category rather than by
    project as presented in the immediately following table. Please revise your disclosure on page 325 to identify the specific factor(s)
    causing the reductions of outside research and services allocable to such research and developments expenses. Revise the disclosure
    on page 327 to explain the changes for the annual periods presented by project rather than by expense category, providing quantifications
    where necessary. Clearly identify the underlying trends and management’s decisions that led to the changes that are reflected
    in the periods presented.

RESPONSE:

    We
    have reviewed your revision related to our prior comment 46. Please further expand your discussion of the changes in research and
    development expenses by category on pages 339 and 341 to identify the specific factor(s) causing the most material changes therein
    for the periods presented. For example, for the year ended December 31, 2022, there was a $1.2 million decrease in R&D labor
    and a $814,018 decrease in Outside lab analysis. Your revised disclosure should describe why, exactly, there was such significant
    changes in these categories. Further, it should be clear into what line item the descriptions you provide should be included. For
    example, while you refer to “contract manufacturing” on both pages 339 and 341, in the former instance it appears that
    contract manufacturing might be reflected within “Consulting services” bu

condition is waivable, please further revise your disclosure to indicate whether
recirculation or resolicitation of shareholders will occur prior to the vote if the listing
application is not approved but the condition is waived. If AgeX shareholders will not
have certainty regarding the listing of the combined company's shares at the time they are

addresses the potential consequences of the parties waiving the condition and the closing
occurring without the NYSE listing, including but not limited to the liquidity implications

13.We note your response to our prior comment 52.  Please address the following:
•Tell us and revise as necessary to reconcile the apparent inconsistency in your
conclusion to account for the merger as a reverse recapitalization for accounting
purposes with your response to prior comment 52 that you do "not believe that it is a
“shell company” as defined in Rule 405 of the Securities Act of 1933 (the ' Securities
Act') or Rule 12b-2 of the Securities Exchange Act of 1934 (the ' Exchange Act ') or
that it will become one prior to the consummation of the Merger because the
Company believes that it has, and will continue to have through the consummation of
the Merger, operations and assets that are more than nominal."
•Clearly explain how you determined that the company holds only nominal assets as
the definition of a shell company requires for reverse recapitalization accounting
purposes.
•Explain how you considered the retained revenue streams, research and development
expense activity, and other activity as reflected in your general and administrative

recapitalization accounting.
•Tell us how you considered the extent to which AgeX has other intangible assets
which would be recorded if the merger were accounted for as a reverse acquisition.

                                            Agreement, “AgeX may be required to pay Serina a termination fee of $1,000,000 million

    Registration
    Statement on Form S-3

Ladies
and Gentlemen:

This
letter is being submitted in connection with the filing of a Registration Statement on Form S-3 by AgeX Therapeutics, Inc. (the
“Company”) to register for sale under the Securities Act of 1933, as amended (the “Securities Act”), up
to $50,000,000 in aggregate offering price of (a) shares of the common stock, par value $0.0001 per share of the Company (the
“Common Stock”), (b) shares of the preferred stock, par value $0.0001 per share, of the Company (the “Preferred
Stock”), (c) warrants to purchase Common Stock or Preferred Stock (the “Warrants”), and (d) units comprised
of one or more of the Common Stock, the Preferred Stock, or the Warrants in any combination (the “Units”). The Common
Stock, Preferred Stock, Warrants, Units, and any shares of Common Stock or Preferred Stock included in Units or issuable upon
exercise of Warrants or conversion of convertible Preferred Stock are collectively referred to as the “Primary Offering
Securities”). The Primary Offering Securities may be offered for sale from time to time pursuant to prospectus supplements
that will be filed with respect to each such offering.

Included
in the Registration Statement is the first prospectus supplement for the offer and sale of up to $12,600,000 of shares of Common
Stock from the Primary Offering Securities, which may be offered and sold from time to time in “at the market” transactions
within the meaning of Rule 415 under the Securities Act pursuant to a Sales Agreement with Chardan Capital Markets LLC acting
as sales agent for the Company (the “ATM Offering”).

The
Registration Statement also pertains to shares of Common Stock (the “Resale Shares”) that are being registered for
resale by a securityholder referenced in the base prospectus as the Selling Securityholder. The Resale Shares include 16,447,500
shares of Common Stock that are issued and outstanding and held by the Selling Securityholder as of the date of this opinion,
and 2,769,229 shares that are issuable upon the exercise of certain Common Stock purchase warrants (“Resale Warrants”)
held by the Selling Securityholder.

The
Company qualifies for the use of Form S-3 under General Instruction I.B.6. The aggregate market value of AgeX’s outstanding
voting and nonvoting common equity held by non-affiliates computed in accordance with General Instruction I.B.6 is $37,903,011,
based on 20,712,465 shares of common stock held by non-affiliates and a $1.83 closing price of the common stock on the NYSE American
on a date within 60 days prior to the date of the Registration Statement. No securities have been offered by AgeX pursuant to
General Instruction I.B.6. of Form S-3 during the prior 12 calendar month period.

    Preliminary
    Proxy Material

Ladies
and Gentlemen:

This
letter is being submitted on behalf of AgeX Therapeutics, Inc. (“AgeX”) in response to your comment letter of November
13, 2020 regarding AgeX’s preliminary proxy statement. Set forth below is your comment with our response, including a reference
to amended disclosures added to the preliminary proxy statement that AgeX is filing concurrently with this letter.

Juvenescence
Proposal, page 24

Comment
1. We note your disclosure that the Chairman of your Board of Directors, Dr. Bailey, is the Chief Executive Officer of
Juvenescence Limited. Please disclose what, if any, consideration the Board gave to this potential conflict of interest in
evaluating this proposal.

AgeX
has added, under a new subheading “Certain Conflict of Interest Considerations,” disclosure of considerations
given by the Board of Directors (the “Board”) to potential conflicts of interest related to Mr. Bailey’s status
as the Chief Executive Officer of Juvenescence Limited (“Juvenescence”). As disclosed, approval of the New Loan Agreement
and New Warrant Agreement, pursuant to which Juvenescence made the convertible loan and received the New Warrants that are the
subject of the Juvenescence Proposal, was delegated to the Audit Committee of which Mr. Bailey is not a member. Mr. Bailey abstained
from that delegation of authority and from the deliberations of the Audit Committee. Mr. Bailey also abstained from the Board’s
recommendation that AgeX stockholders vote to approve the Juvenescence Proposal. As discussed in the revised preliminary proxy
statement, in approving the New Loan Agreement and New Warrants, the Audit Committee applied certain considerations required by
AgeX’s Related Person Transaction Policy.

Other
Revisions

The
revised preliminary proxy statement also reflects certain other changes, including updates to information as to the total amount
of loans obtained by AgeX under the New Loan Agreement and the issuance of New Warrants, and certain possible consequences of
Juvenescence becoming a majority stockholder.

Annual
Meeting Date and Planned Mailing Date

AgeX’s
annual meeting will be held on December 28, 2020. AgeX plans to mail the proxy materials on or around November 27, 2020. Given
the tight time frame, AgeX would greatly appreciate the staff giving this response their prompt attention.

    Therapeutics, Inc.

    Preliminary
    Proxy Material

Ladies
and Gentlemen:

This
letter is being submitted in connection with the filing of a preliminary proxy statement and form of proxy by AgeX Therapeutics,
Inc. (“AgeX”). The proxy materials relate to AgeX’s annual meeting of stockholders at which the stockholders
will be asked to vote on the following matters: (1) the election of directors; (2) the ratification of the appointment of AgeX’s
independent registered public accountants; and (3) approval of a proposal to allow Juvenescence Limited (“Juvenescence”),
AgeX’s largest stockholder, to acquire additional shares of AgeX common stock through the exercise of warrants or the conversion
of all or a portion of the principal amount of certain loans to AgeX if as a result of the acquisition Juvenescence would (a)
acquire more than 19.9% of AgeX common stock outstanding as of March 30, 2020 at a price less than the applicable market
value of AgeX common stock or book value per share, and/or (b) own 50% or more of the outstanding shares of AgeX common stock
(the “Juvenescence Proposal”).

The
Juvenescence Proposal

The
Juvenescence Proposal is being submitted for stockholder approval in accordance with a covenant in a Secured Credit Facility Agreement,
as amended (the “Loan Agreement”), between AgeX and Juvenescence pursuant to which Juvenescence has been providing
debt financing to AgeX. AgeX has issued to Juvenescence certain common stock purchase warrants (“Warrants”), in amounts
determined by a formula in the Loan Agreement, as loan funds are advanced to AgeX.

AgeX
common stock is listed on NYSE American (the “Exchange”) and AgeX must comply with the listing requirements of the
Exchange. Section 713 of the Exchange Company Guide requires listed companies to obtain stockholder approval as a prerequisite
to Exchange listing approval before: (i) issuing additional shares in a transaction involving the sale, issuance, or potential
issuance by the issuer of common stock (or securities convertible into common stock) equal to 20% or more of stock outstanding
(determined as of the date of the particular transaction agreement) for less than the greater of book or market value of the Exchange
listed common stock (the “20% Rule”), and (ii) issuing shares that will result in a change of control of the listed
company (the “Change of Control Rule”). While the Exchange has not defined “change of control”, the Exchange
considers any issuance of stock to be subject to the Change of Control Rule if the issuance of stock would result in a stockholder
holding 50% or more of a listed company’s outstanding stock.

Securities
and Exchange Commission

November
5, 2020

Page
2

The
Loan Agreement permits the outstanding principal amount of loans to be converted into shares of AgeX common stock. To comply with
the Exchange’s 20% Rule and Change of Control Rule, the Loan Agreement contains a “19.9 % blocker” provision
and a “change of control blocker” provision intended to prevent an exercise of the loan conversion rights that would
violate the 20% Rule or the Change of Control Rule. A Warrant Agreement governing the Warrants also contains a “change of
control blocker” provision intended to prevent an exercise of Warrants that would violate the Change in Control Rule. The
exercise price of the Warrants is set with reference to the market price of AgeX common stock so the 20% Rule would have no effect
on the exercise of Warrants by Juvenescence. If the Juvenescence Proposal is approved by AgeX stockholders, Juvenescence would
be able to acquire additional shares of AgeX common stock in compliance with the Exchange’s rules through the conversion
of the principal amount of outstanding loans or through the exercise of Warrants without the limitations that otherwise would
be imposed by the “19.9% blocker” and the “change of control blocker” provisions of the Loan Agreement
or Warrant Agreement.

The
preliminary proxy statement contains a more detailed discussion of the Juvenescence Proposal, including possible consequences
of Juvenescence acquiring 50% or more of the outstanding shares of AgeX common stock.

Annual
Meeting Date and Planned Mailing Date

AgeX’s
annual meeting will be held on December 28, 2020. AgeX plans to mail the proxy materials on or around November 27, 2020.

Please
direct any questions or comments to the undersigned at (415) 298-2171 or by email to rsoroko@twsglaw.com with a copy to AgeX’s

Ladies/Gentlemen:

This
letter is being submitted on behalf of AgeX Therapeutics, Inc. (“AgeX”) in response to your letter dated May 18, 2020
regarding AgeX’s Form 10-K for the fiscal year ended December 31, 2019 filed on March 30, 2020.

Comment:

Form
10-K for the fiscal year ended December 31, 2019

Controls
and Procedures, page 99

    1.
    You state that a report of management’s assessment
regarding internal control over financial reporting is not included “due to a transition period established by rules of
the Securities and Exchange Commission for newly public companies.” Please tell us your consideration of Item 308(a) of
Regulation S-K, particularly the Instructions thereto, which indicate that such transition period would apply to only the first
annual report. Alternatively, amend your filing to so provide.

Response:

AgeX
has complied with Regulation S-K Item 3.08(a) and is filing an amendment to its Form 10-K containing the required disclosure.
Please note that the Section 302 certifications as originally filed as Exhibit 31 with the Form 10-K did include the required
certifications with regard to internal control over financial reporting.

Please
direct all correspondence and communications with respect to the Form 10-K to the undersigned at rsoroko@twsglaw.com and
