LS1-iPSCs express the cell surface pluripotency markers SSEA4, TRA-1-60, and TRA-1-81. LS fibroblasts are negative for cell surface pluripotency markers, whereas LS1-hiPSCs reprogrammed from these cells become positive for SSEA4, TRA-1-60, and TRA-1-81 stem cell markers. LS1-hiPSCs expression is comparable with healthy control H9-hESCs and BJ-hiPSCs stem cells. Scale bar = 50 μm. Image inserts contain corresponding DAPI nuclear counterstain. DAPI, 4′,6-diamidino-2-phenylindole.
