PSC-833 augments apoptosis in TF1 cells deprived of growth factors.

Percentage loss of TF1 viability after culture for 23 and 30 hours in 1% FCS without growth factors in the absence (filled circles) or presence of 0.5 μmol/L (filled diamonds) or 1 μmol/L (unfilled circles) PSC-833 (the mean plus or minus SE of 4 experiments). Data points were plotted after the subtraction of control values from cells grown in the presence of GM-CSF with or without the appropriate dose of PSC-833.
