Cell proliferation in response to RA ​+ ​AA treatment. (A) Changes in cell number induced by treatment with AA (0.5 ​mM), RA (10−5 ​M) and (RA ​+ ​AA) for 12 days. All three treatments produced a significant reduction in the number of cells from day 6 of treatment relative to the control group. ∗p ​< ​0.05. The data are expressed as mean ​± ​SD. (B) Photomicrograph of hDPSC cultures. The cells were treated with RA (10−5 ​M), AA (0.5 ​mM) and RA ​+ ​AA for 7, 14 and 21 days. Bar: 200 ​μm.
