Figure 4

Generation of CHM3 iPSC and iPSC-derived RPE. qPCR analysis shows the mRNA levels of the host pluripotency markers OCT3/4 (A), LIN28 (B), SOX2 (C) and NANOG (D) in CHM3 iPSC (black bars) as compared to the original fibroblasts. Data are expressed as mean ± SEM, n = 3. (E) Karyotype analysis of the CHM3 iPSC did not detect large chromosomal rearrangements. (F) The pigmented, cobblestoned appearance of the iPSC-derived RPE monolayer. (G) qPCR analysis of the expression of the typical RPE markers MERTK, RDH5, TYR, ZO-1, PAX6, BEST1 and RLBP1 shows an upregulation of expression (in relative units) in the CHM3 iPSC-derived RPE (grey bars) as compared to fibroblasts (black bars). Data are expressed as mean ± SEM, n = 3. (H) Weekly recordings of the transepithelial resistance (TER) following P3 seeding are presented as normalized Ω/cm2. Data are expressed as mean ± SEM, n = 3.
