FGF activation of FGFR1 induces an increase in cell number. A: TERT-NHUC (control) and TERT-NHUC expressing FGFR1α or FGFR1β were cultured with heparin and FGF (100 ng/ml) for 96 hours. FGFR1α and FGFR1β cells were cultured with low concentrations of FGF1 (B) or with FGF2 (C) for 96 hours. Measurements are viable cell numbers taken from an average of three experiments, and error bars represent SD.
