Sox-17 expression in renal cells. a RC F38, b RC M37, and c RC M43 indicate renal cells cultured from donors of the following ages (years)/genders: 38 (female), 37 (male), and 38 (male), respectively. The blue colour indicates nuclear staining of individual cells for all Sox-17 staining for respective donors. Depending on the quality of samples, the cells were positive for the endoderm marker Sox-17 (red colour) at varying levels. For the phase-contrast images, pictures were taken at 4× magnification and scale bar = 1000 μm. For fluorescent images, pictures were taken at 40× magnification and scale bar = 50 μm
