The effects of estrogen and progesterone on Schwann cell proliferation were studied in cultured segments of the rat sciatic nerve from adult male, female, and newborn rats, by measurement of [3H thymidine incorporation or bromo-deoxy-uridine- (BrdU)-labelling and immunocytochemistry. Estrogen (100 nM-500 nM) enhanced [3H] thymidine incorporation in segments(More)
The factors that control proliferation of Schwann cells during peripheral nerve regeneration are not yet known. In this study we investigated the effects of insulin, insulin-like growth factor I and II (IGF-I and IGF-II), IGF-I analogues, and factors that interfere with their respective receptors, on [3H]thymidine incorporation into cultured nerve segments(More)
Schwann cell proliferation was studied in cultured segments of the rat sciatic nerve by measurement of [3H] thymidine incorporation or through bromodeoxyuridine-(BrdU)-labelling and immunocytochemistry. The aim was to delineate mechanisms involved in the injury-induced proliferative response of Schwann cells. Removal of extracellular Ca2+ by addition of(More)
