Steroid Uptake and ^3H-Uridine Incorporation by Early Hamster and Squirrel Monkey (in Vitro Fertilized) Embryos : Effects of Ovulatory Regimen(Endocrinology)

概要

論文の詳細を見る
Effects of ovulatory regimens were analyzed on the uptake of ^3H-estradiol (E_2) and ^3H-progesterone (P) and incorporation and uptake of ^3H-uridine by hamster and squirrel monkey (in vitro fertilized) embryos throughout early preimplaniation development. E_2 and P uptake increased throughout preimplantation development in both species. The pregnant mare's serum/ human chorionic gonadotropin superovulatory regimen reduced uptake of steroids by the hamster embryo at virtually all stages analyzed. There was no effect on the incorporation of ^3H-uridine (used as an indicator of relative RNA synthesis). The length of FSH treatment had no appreciable effects on steroid uptake by squirrel monkey embryos fertilized in vitro.
