From: Functional significance of CD105-positive cells in papillary renal cell carcinoma
Expression of “stemness genes”. Relative expression of oct4 and sox2 stem-related genes was measured by real-time PCR in relation to the PPIA housekeeping gene. Statistically significant differences were obtained between Caki-2 and ACHN for the oct4 gene. Interestingly, in HKCSC, neither gene was detected. In contrast, the oct4 relative expression in ASE (normal renal cells of embryonic origin) was significantly higher than in the other cell lines
