After ovariectomy and 3 daily injections of progesterone plus one of oestradiol-17 beta, 69% of stromal capillaries of the rat uterus became sheathed with pericytes. On Day 5 of pregnancy the value was 74% but at other times (Days 4 and 6) and with progesterone-only or not treatment less than 15% of capillaries were associated with pericytes. This period of pericyte presence coincides with the time when implantation is possible.
卵巢切除术后,每天注射孕酮加17β-雌二醇一次,大鼠子宫基质毛细血管中有69%被周细胞包裹。妊娠第5天时,这一比例为74%,但在其他时间(第4天和第6天),以及仅使用孕酮或未进行治疗的情况下,只有不到15%的毛细血管与周细胞相关。周细胞出现的这段时间与可能发生着床的时间相吻合。
