Growth characteristics of UC-MSCs compared to BM-MSCs. Triplicate cultures were harvested every 2 days for 14 days, and adherent cells were counted. (A) Growth curve of MSCs at passage 3, (B) Growth curve of MSCs at passage 4, (C) Growth curve of MSCs at passage 5. (D) Population doubling time of UC-MSCs compare to BM-MSCs. Results (N = 3) are expressed as mean ± SD. *P < 0.05: significant difference compared to BM-MSCs.
