rMC-1 cells expressing an hGRK1 promoter-driven mCherry reporter and exogenous hCRX, hNEUROD, hRAX, hOTX2, and EGFP cultured in PDM (CNROE_PDM_1)
rMC-1 cells expressing an mCherry reporter gene driven by the human GRK1 (hGRK1) promoter together with exogenous human transcription factors CRX, NEUROD, RAX, and OTX2 and EGFP. The cells were cultured in photoreceptor differentiation medium (PDM) for 4 weeks.
