本文介绍了一种测定绵羊胎盘不同类型细胞核数目的方法。该方法被应用到6个不同年龄的胎盘的研究和结果已与数据的化学成分和生理的羊胎盘。与胎盘DNA含量的研究一致，在妊娠的最后两个月，胎盘细胞核的总数没有明显的增加。然而，从80天到足月，胎儿间充质细胞核的数量减少，同时伴随着胎儿内皮细胞核的增加。这些变化与胎盘绒毛核心体积的减少和脐带血流量的增加相关。
A method is described for estimating the number of nuclei of different cell types in the sheep placenta. The method was applied to the study of six placentas of different ages and the results have been correlated with data on the chemical composition and the physiology of the ovine placenta. In agreement with studies of placental DNA content, there is no demonstrable increase in the total number of placental nuclei in the last two months of gestation. However, the number of fetal mesenchymal nuclei decreases and there is a concomitant increase of fetal endothelial nuclei from 80 days to term. These changes correlate with a decrease in volume of the core of the placental villi and increase in umbilical blood flow.
