The growth characteristics of cells in culture change dramatically upon tumorigenic transformation. By the use of selective culture media supplemented with growth factor-inactivated serum, the changes in requirements for externally added polypeptide growth factors can readily be assessed. Certain nontumorigenic cell lines, including normal rat kidney (NRK) fibroblasts, can obtain the growth characteristics of a tumor cell when they became phenotypically transformed by addition of specific… CONTINUE READING
