Hormonal control of uterine growth: alterations in luminal epithelial deoxyribonucleic acid synthesis after intraluminal application of estrogen.

abstract：:Somatostatin has been demonstrated to negatively regulate pancreatic growth in vivo. In this study we used the AR4-2J rat pancreatic acinar tumor cell line to investigate the effect of a stable somatostatin analog, SMS 201-995 (SMS) on cell proliferation. SMS induced an antiproliferative effect on both serum or epider...
