[Cell strains of A431 epidermoid carcinoma with altered epidermal growth factor reception].

Epidermal growth factor inhibits proliferation of A431 cells when added to the cultural medium. Strains of A431 cells, resistant to EGF (800 ng/ml), were obtained by one-step selection after the treatment of these cells by 1-methyl-3-nitro-1-nitrosoguanidine (MNNG). Two of the obtained strains differ from the initial line in the EGF reception.
