Proliferation rate of adipose-derived MSCs: (a) The cell growth rates of AbSCs, BFPdSCs, and HdSCs at different passages (P3–P8) as determined by trypan blue staining for detection of viable cells. Note that the highest proliferation rate was related to BFPdSCs. (b) Population doubling time of given cells at different passages (P3–P8) after 5 days with the initial density of 10⁴ cells/well. Note that the shortest doubling time was observed for BFPdSCs. Different letters indicate significant difference at P ≤ 0.05.
