Activation of FGFR1 regulates proliferation and survival. A, Immunoprecipitation of FGFR1 from NHUC-FR1 cultured with FGF2 for 15, 30 and 60 minutes. Blots were probed with an anti-phosphotyrosine antibody (pTYR) and reprobed with anti-FGFR1 antibody as loading control. B, NHUC-VEC (dashed line) and NHUC-FR1 (solid line) were grown in supplement-free medium with heparin and FGF2 (10ng/ml). C, NHUC-VEC and NHUC-FR1 were grown in supplement-free medium with heparin (black bar), or heparin and FGF2 (grey bar) for 24 hours prior to addition of BrdU. BrdU incorporation was measured by FACS. D, NHUC-VEC and NHUC-FR1 were grown in supplement-free medium for 96 hours in the presence of heparin (black bar), or heparin and FGF2 (grey bar). Viability and apoptosis were analysed by FACS.
