Optical stimulation does not alter the viability of ChR2-GFP-V6.5 ESCs. a The results of the cell viability assay of ChR2-GFP-V6.5 ESCs (trypan blue exclusion assay) in both the photoactivated group and the nonphotoactivated control group are summarized in a bar graph. b Summary graph of the apoptosis of ChR2-GFP-V6.5 ESCs in both the photoactivated group and the nonphotoactivated control group. c, d Flow cytometry quantifying the apoptosis of ChR2-GFP-V6.5 ESCs in the nonphotoactivated and photoactivated groups.
