Resistance to apoptosis induced by serum starvation. MWCL-1 cells were cultured with (a) or without (b) FCS for 6 h, and then the apoptotic cells in the three subpopulations were detected with Annexin V staining. (c) Proportion of Annexin V-positive cells was shown. *P<0.05 when compared with the presence of FCS.
