Fig 8. Effects of p21 knockdown on senescence in the ASCs.

Fig 8

A and B: β-Galactosidase staining. A, S1-iRNA ASCs. Note these cells were barely stained, changes in cell volume were not detectable. B, Empty-vector-iRNA ASCs. Note most of these cells were stained in deep blue (senescent cells), with an increase in cell volume. C, Comparisons between the S1-iRNA ASCs, the empty-vector-iRNA ASCs and the untreated ASCs in the percentage of the senescence positive ratio of the cells. Note that senescent rate of the cells infected by S1-siRNA was significantly lower than those of the other two groups (P<0.05).
