✦ Synopsis

Abstract

Earlier work showed that thrombin stimulates proliferation of human fibroblasts in serumfree medium. This work demonstrates (1) that thrombin has to be present during most or all of the G1 period to ensure maximal DNA synthesis, (2) that DNA synthesis increases about three hours later after thrombin than after serum treatment, (3) that both thrombin and serum activate transport of uridine, D‐2‐deoxy‐glucose and putrescine, (4) that thrombin is able to increase ^3^H‐thymidine incorporation also in SV40 transformed human fibroblasts, in HeLa cells and in two continuous monkey cell lines.

The effects of growth factors on inositol-containing phospholipids were investigated to test the hypothesis that alterations in their metabolism are involved in mitogenic stimulation. Thrombin and EGF stimulated comparable increases in the synthesis (30-50%) and degradation (2040%) of phosphatidylin

## Abstract The effect of insulin on hexose transport in cultured human skin fibroblasts. Studies were carried out on cultures of human skin fibroblasts to explore the effect of insulin on hexose transport in serum‐starved monolayers. Insulin (100 mU/ml) stimulated 2‐deoxy‐D‐glucose transport (30%
