Figure 3

FACS-based purification plots of human induced pluripotent stem cells (hiPSCs) and OCT4SRE activity. (a) The High35% Stb/eGFP-double positive fraction post-2x FACS SORT was collected. (b) Indirect OCT4SRE-mediated Stb expression assessment was performed after OCT4 activation by reprogramming to hiPSC by ICC staining for RFP where blue = DAPI, RFP = Stb expression driven by OCT4SRE, eGFP = EF1α-eGFP. (Bar = 200 μm). eGFP, enhanced green fluorescent protein; EF1α, elongation factor 1α; FACS, fluorescence-activated cell sorting; hiPSC, human induced pluripotent stem cell; OCT4, octamer-binding transcription factor 4; OCT4SRE, OCT4-short response element.
