Fig. 2From: Diminished expression of major histocompatibility complex facilitates the use of human induced pluripotent stem cells in monkeyBiological characteristics of knockout iPSCs. a WT-iPSCs, B2M−/−-iPSCs, CIITA−/−-iPSCs, and B2M−/− and CIITA−/−-iPSCs had normal clone morphology, were capable of forming embryonic body, had alkaline phosphatase activity, and were positive for Oct3/4, Sox2, and SSEA4. b, c Knockout of B2M and/or CIITA did not affect iPSC apoptosis. d Knockout of B2M and/or CIITA did not affect iPSC proliferation.
