Oestradiol-17 beta uptake in vitro into the nuclei of endometrium from different regions of the human uterus.
Specimens of endometrium from the vault, body and lower body regions of the same human uteri were incubated separately for 30 min in vitro in the presence of 1-6 times 10-9 M 3H-oestradiol. Uptake into the nuclei was variable but in general the vault region endometrium was least active in nuclear accumulation of the hormone, especially in secretory phase endometrium. This suggests that intra-uterine variations found in oestradiol uptake in vivo are due to regional differences in the state of the tissue itself.
