Protein expression of other stem cell genes exhibits the same tendency as Nanog. a and b) Oct4 and Sox2 expression increased in the GFP (+) cells compared with the GFP (−) cells according to western blot analysis. c and d) Oct4 and Sox2 expression in the GFP (+) cells clearly increased under DHT treatment compared with ASC-J9 treatment based on western blot analysis, which was also consistent with the Nanog expression trend
