The reprogramming efficiency of Nanog-GFP MEF using retrovirus vector-based L507A mutants with pro-reprogramming factors
(A) Typical morphology of Nanog-GFP colonies in the reprogramming Nanog-GFP MEF on day 25 of reprogramming in KLF4 wildtype (WT) or L507A mutant with pro-programming factors. Scale bars, 200 μm.
(B) The number of Nanog-GFP colonies in the reprogramming Nanog-GFP MEF calculated on day 25 of reprogramming in KLF4 WT or L507A mutant with pro-programming factors. Results are mean and SE, n = 4. p values calculated with the t test were shown based on the comparison between WT and L507A KLF4 conditions.
(C) The ratio of Nanog-GFP colonies to the total colonies in the reprogramming Nanog-GFP MEF was calculated on day 25 of reprogramming in KLF4 WT or L507A mutant with pro-programming factors. Results are mean and SE, n = 4. p values calculated with the t test were shown based on the comparison between WT and L507A KLF4 conditions.
