Simultaneously, immunohistochemistry of the tumor derived from miPS-PGE2P cells showed strong immunoreactivity to anti-E-cadherin, -Ki67, and -CD44 antibodies indicating high proliferation rate with CSC subpopulation as well as heterogeneous intercellular adherence while teratoma section did not show any of these immunoreactivities (Fig. 3E). The gene discussed is CDH1; the disease is neoplasm.
