Ovaries from normal and hypophysectomized 16-day-old duck embryos were cultured in vitro using 14C-sodium acetate as a precursor and the synthesis level of both 14C-labelled oestrone and oestradiol was determined in each case. The results demonstrate that the synthesis of oestradiol is under hypophyseal control as early as 16 days of incubation, while oestrone synthesis seems not yet to be dependent on pituitary LH at this same age.
使用14C-醋酸钠作为前体,对正常和垂体切除的16日龄鸭胚胎的卵巢进行体外培养,并分别测定14C标记的雌酮和雌二醇的合成水平。结果表明,早在孵化16天时,雌二醇的合成就受垂体控制,而在相同年龄时,雌酮的合成似乎尚未依赖于垂体促黄体生成素。
