Figure 3. Relative gene expression of urothelial markers.

Real time-PCR performed on urothelial-like cells differentiated from ADSCs, cultivated in either conditioned medium (CM) or unconditioned urothelial cell media (UCM) in the presence of either 5% pHPL, 2.5% pHPL or 10% FBS. Uninduced ADSCs were used as the calibrator sample. (A) Relative expression of cytokeratin-18, (B) cytokeratin-19 and (C) uroplakin-2. * P < 0.05, ** P < 0.01. All experiments were repeated at least three times.
