FBS starvation-induced cell death is partially rescued by VEGF. MM1s cells were starved overnight in RPMI 1640 supplemented with 0.5% FBS in 96-well plates, followed by culture for 48 hours with the indicated doses of VEGF and FBS. Proliferation was measured by ³H-thymidine incorporation. Results shown are compared with control cells cultured in RPMI 1640 supplemented with 10% FBS. Error bars indicate standard deviation.
