title: Investigations upon adenohypophysial cell proliferation in vitro: influence of oestradiol, thyrotropin releasing hormone, dibutyryl cyclic AMP and theophylline.
abstract: Mitotic indices were counted in adenohypophysial fragments cultured in vitromthe cultures exposed to 17-beta oestradiol, synthetic thyrotropin releasing hormone (TRH) and dibutyryl cyclic AMP showed a higher number of mitoses as compared with respective controls. However, theophylline decreased the mitotic index in cultured adenohypophysis.
