Ectopic expression of Atoh1 promotes DPSC proliferation. DPSCs treated with Adv-Null and Adv-Atoh1 were maintained in the growth medium. A Total RNA was isolated after 5 days for qPCR quantification of Atoh1 expression (n = 6). B Total proteins were extracted after 5 days for Western blotting analysis of Atoh1. C MTT cell proliferation assay was performed on day 1, 3, and 4 after viral vector treatments (n = 3)
