## Abstract Epidermal growth factor (EGF) is a mitogen for Swiss 3T3 cells. Short incubation periods with physiological concentrations of EGF induced increased binding of Swiss 3T3 cells to Con Aβcoated nylon fibers. This effect was not induced in an EGF nonβresponsive 3T3 variant, in the transform

β¦ Synopsis
Epidermal Growth Factor (EGF) at concentrations of 10(-9) to 10(-10) M initiates cell division in both confluent and low density non-dividing 3T3 cells. Four days after addition of EGF to confluent or low density non-dividing 3T3 cells there is a 2- and 5-fold increase, respectively, in cell number.

Incubation of Swiss mouse 3T3 cells at 37Β°C with bovine brain-derived growth factor (BDGF) decreased the cell surface '251-EGF binding activity of these cells by 70-80%. This down-modulation of the EGF receptor by BDGF was time, temperature, and dose dependent. Scatchard plot analysis indicated that
Institute for Diabetes and Endocrinology, La lolla, California 92(1.?7 Treatment of Swiss 3T3 fibroblasts with basic fibroblast growth factor (bFGF) lead to a rapid reduction in epidermal growth factor (EGF) binding and a slower inhibition of EGF receptor autophosphorylation. The reduction in bindi
Epidermal growth factor (EGF) stimulates the initiation of DNA synthesis in Swiss 3T3 cells after a constant prereplicative period of 14-15 hours. The final rate of initiation follows apparent first-order kinetics and can thus be quantified by a rate constant k. The value of k can be changed by late
