title: 3T3 variants unable to bind epidermal growth factor cannot complement in co-culture.
abstract: A Swiss-Webster 3T3 variant, called 3T3-ENR7, unable to divide in response to epidermal growth factor was isolated by the mitogen-colchicine selection technique. Like the other EGF non-proliferative variants (3T3-NR6 and 3T3-TNR2), 3T3-ENR7 was unable to bind 125I-EGF. Pairwise co-culture of the three independently isolated EGF non-responsive variants did not restore mitogenic responsiveness to EGF.
