Spontaneously transformed NRK cells lose their mitogenic response to epidermal growth factor.


To understand the relationship between growth factor-induced mitogenesis and spontaneous cell transformation, a clonal isolate of epidermal growth factor (EGF)-responsive NRK cells was passed in vitro until morphologically transformed variants arose. Subclones of EGF responsive (Cl-3) and EGF nonresponsive (Cl-10) NRK cells were isolated. Cl-3 cells grew as… (More)
