meaning of scientific or technical terms the first time they are used in
                                                        order to ensure that
lay readers will understand the disclosure. For example, please briefly
                                                        explain what you mean
by iPSC-derived NK and T therapeutics and CRISPR-

                                                        86. Given the stage of

18.      We note that on June 21, 2019, Prior Century and Bayer entered into a
commitment
         agreement to initially capitalize the Company. Please address the
following:

                We note that in exchange for issuing 67,226,891 common units to
Prior Century, the
              Company acquired substantially all of Prior Century   s assets,
assumed all of its
              liabilities and assumed the operations of Prior Century and after
Bayer's cash
              contributions to the Company, Prior Century owned 78% of the
Company's equity
              interests. We further note that notwithstanding its 78% equity
interest, Prior
              Century accounts for its investment in the Company under the
equity method of
              accounting. With reference to specific terms of Bayer's approval
and veto rights,
              please tell us and expand your disclosures to clarify how you
determined that Prior
              Century did not retain control the Company; and
                Provide us with a sufficiently detailed explanation of how your

              value of the 67,226,891 units issued to Prior Century. Expand

      equity interests as determined in connection with its initial
capitalization as discussed in
      Note 3. In this regard, we note that subsequent to the initial
capitalization of the
      Company, Prior Century has no significant operations other than its
investment in the
      Company.
