Factor dependence of control and MDR-1 expressing FDCP-mix. Data show viable cell counts at different time points after factor withdrawal, for one bcl-2-expressing clone (open squares), parental FDCP-mix cells (open triangles), the mean of four tNGFR transduced clones (open circles) and the mean of four MDR-1-transduced clones (solid triangles). The data represent the mean of three experiments ± s.e.m.
