The proliferation capacity of hUC-MSCs

<p>: (a).Growth curve analysis by MTT assay at P₈ of MSCs from the ten donors. Data shown are the mean ± SEM of values form ten donors. (b). The PDT of hUC-MSCs at P₈ from donor 2 was different from the one from donors 5(<i>P<0.05</i>) in the same culture medium. The PDT of serum-containing conditions was shorter than serum-free cultured ones (P<0.05)
