1 Epidermal growth factor (EGF) (50 ng/ml) and platelet-derived growth factor (PDGF)-BB induced an elevation of the [3H]thymidine incorporation into cell DNA from 154 +/- 7 (basal value) to 1270 +/- 95 and 1552 +/- 178 cpm/microgram protein (mean +/- S.D., n = 3). Tritium epidermal growth factor like 1 Rattus norvegicus
2 Epidermal growth factor (EGF) (50 ng/ml) and platelet-derived growth factor (PDGF)-BB induced an elevation of the [3H]thymidine incorporation into cell DNA from 154 +/- 7 (basal value) to 1270 +/- 95 and 1552 +/- 178 cpm/microgram protein (mean +/- S.D., n = 3). Tritium epidermal growth factor like 1 Rattus norvegicus
3 In contrast to phenylephrine, oxymetazoline caused an elevation of the PDGF-BB- and EGF-induced [3H]thymidine incorporation to 1561 +/- 143 and 2086 +/- 235 (means S.D., n = 3), respectively. Tritium epidermal growth factor like 1 Rattus norvegicus
4 In addition, EGF (1 to 50 ng/ml) induced a dose-dependent increase of [3H]thymidine incorporation from 154 +/- 7 (basal value) to 486 +/- 35 (1 ng/ml), 912 +/- 74 (5 ng/ml), 1019 +/- 40 (25 ng/ml) and 1270 +/- 95 (50 ng/ml) cpm/microgram protein (mean +/- S.D.). Tritium epidermal growth factor like 1 Rattus norvegicus
5 In the presence of 10(-6) M oxymetazoline, 1, 5, 25 and 50 ng/ml EGF caused an increase of [3H]thymidine incorporation to 633 +/- 101, 1124 +/- 87, 1231 +/- 101, and 1561 +/- 89 cpm/microgram protein (mean +/- S.D.). Tritium epidermal growth factor like 1 Rattus norvegicus
