| Abstract |
Epidermal growth factor (EGF) has been shown to stimulate DNA synthesis in rat parenchymal hepatocytes both in vivo and in vitro (4,9). The authors report here that this response in vitro is dependent on the amino acids present in the media. Of all the amino acids, proline has the strongest effect. The response to EGF is absent without proline and none of theother amino acids can substitute for it. Added proline (1mM) to the media caused the labeling index to increase from 11% to 55% in the presence of 50 ng/ml EGF and insulin. In the presence of proline, small additional increases of the EGF effect on DNA synthesis were stimulated by phenylalanine and tyrosine. (Copyright (c) 1985 Tissue Culture Association, Inc.) |
