Growth factor regulation by Atoh1. DPSCs treated with Adv-Null and Adv-Atoh1 were maintained in the odontogenic medium. RNA was isolated for qPCR analysis. A Expression of BMP2 and BMP7 on day 7 and 14 (n = 3 or 6). B Expression of sFRP2, Axin2, PDGF, and Osteocalcin (n = 3 or 6) on day 7. C Expression of VEGF-A and HIF1α on day 7 (n = 3 or 6)
