   1.                                                   Please revise the risk
factors on pages 76 and 93 and the related disclosure in the
                                                        Summary to clarify if

         VIEs may be attributable to Graycell Bioscience, and the basis to
support
         your determination that the prohibition under the Negative List does
not apply to your
         operations. Please also revise to define the term "WFOE" at its first
use.

         Additionally, please expand your disclosure to address the following
risks, as applicable:
             intellectual property rights and protections may be insufficient
to protect
             your intellectual property in China;
             the increased global focus on environmental and social issues and
China's potential
             adoption of more stringent standards in these areas may adversely
impact your
             operations;
             potential adverse tax-consequences to shareholders if you are
determined to be a
             resident enterprise for PRC tax purposes; and
             Chinese governmental authorities have significant discretion that
can be used to
             influence how you conduct your business and operations.

2.       We note your response to comment 2 and reissue with respect to
references to potentially
         enhanced safety and efficacy and disclosure that implies the safety
profile of your product
         candidates has been established.
3.       We note your response to comment 4 and reissue with respect to
references to product
         candidates as potentially    first-in-class.
4.       We note your response to comment 22 indicating that you do not have
access to data from
         the Phase 1 investigator-initiated trials until the data is published.
Please revise your
         disclosure in the Summary to highlight this limitation. It should be
clear from your
         disclosure throughout your prospectus that you do not have access to
data while the trials
         are being conducted and are dependent on receiving published data.
Revise any references
         to partnering on these studies to explain your involvement. Similarly,
revise your pipeline
         table presentation to convey the limited scope of your involvement and
that you do not
         have access to data from the investigator-initiated studies until the
data is published.
         Lastly, please highlight the risks associated with your lack of access
to the data under an
         appropriate heading in the Risk Factors section.
Risk Factors, page 18

5.       To the extent any risk factor included in your prospectus could
involve any registrant or
         any offering, revise this section to relocate all such risk factors at
the end of this
         section under the caption    General Risk Factors.    Refer to Item 3
of form F-1 and 105(a)
         of Regulation S-K and Section II.D. of Release No. 33-10825,
Modernization of
         Regulation S-K Items 101, 103, and 105    (Oct. 8, 2020).

revise.
Loan Agreements, page 134

8.       We note your response to comment 13 and do not agree with your
conclusion that your
         loan agreements are not material contracts required to be filed as
exhibits. In this regard,
         we note that you have a history of losses, will continue to incur
research and development
         expenses and may not be profitable in the near future. Please file
your loan agreements
         with Bank of China, China Construction Bank and China Merchants Bank
as exhibits to
         your registration statement.

9.       Your revised disclosure presents research and development expenses for
each of your
         significant product candidates and separately by the major components
of your research
         and development expenses. Please clarify how these two tables are
integrated or revise to
         incorporate both tables into one table that reconciles to total
research and development
         expense on the Consolidated Statements of Comprehensive Loss.
Share-Based Compensation, page 143

10.      Once you have an estimated offering price or range, please explain to
us how you
         determined the fair value of thecommon stock underlying your equity
issuances and the
         reasons for any differences between the recent valuations of your
common stock leading
         up to the IPO and the estimated offering price. This information will
help facilitate our
         review of your accounting for equity issuances including stock
compensation. Please
         discuss with the staff how to submit your response.

extent you have not
         revised the disclosure to define Grade 1 and higher adverse events as
discussed in your
         response.

12.      We reissue comment 22 in part. To the extent you do not have access to
study data for the
         studies you describe in your response, revise this section to explain
your limited
         access. Tell us how you have access to the data you do have, and
whether you have any
         agreement regarding the sharing of data or information. Tell us when,
if ever, you expect
         to obtain access to full information on the studies, including not
only results but the
         underlying data collected. For example, tell us whether you will
obtain access to the
         information prior to submitting your IND applications to the FDA. In
addition, revise to
         state what actions you have taken in the studies for which you do not
have access to the
         data. For example, you continue to state "our trial" (page 163) and
"we observed" (page
         164) with respect to the GC012F study, and "we administered all
patients with a single
         infusion" in the GC027 study, on page 167. To be clear that you are
not conducting these
         studies, revise throughout this section to avoid the passive voice and
state who is taking
         the actions you describe.
Intellectual Property, page 173

13.      We note your response to comment 23 and do not agree with your
conclusion that your
         license agreement with ProMab is an ordinary course contract not
required to be filed as
         an exhibit to your registration statement. Further, we note your
disclosure on page 64
         that "[i]f we fail to comply with the obligations . . . our licensors
may have the right to
         terminate the license," and, if terminated, you "may not be able to
develop, manufacture,
         market or sell the product covered by our agreements," which "could
materially adversely
         affect the value of the product candidates being developed under any
such agreement."
         Please file your license agreement with ProMab as an exhibit to your
registration
         statement.
14.      We reissue comment 24 in part. Revise to describe the scope of patent
protection you
         seek with respect to your patent applications described in this
section.
Taxation, page 245

15.      We reissue comment 28 in part. Revise the discussion of PRC tax
consequences to
         provide an opinion of counsel as to the material PRC tax consequences
of the ownership
         of your ordinary shares represented by American Depositary Shares.
