人与灵长类胎盘绒毛中心是一个含有胎儿血管床、许多结缔组织细胞及巨噬细胞(Hofbauer细胞)的部位。以往亚显微结构的研究集中于滋养叶细胞的发展和分化,对间质部分偶然予以注意。Hertig检查猴及人的早期妊娠标本,认为绒毛中心的这些组织来自滋养叶组织的原位分层。本文从恒河猴孕16～60天的胎盘绒毛取更密的各期标本检查以下内容:(1)内皮细胞的来源及胎盘绒毛中血管生成的机理。(2)Hofbauer细胞的来源。(3)间质中网质细胞的来源。结果不支持Hertig的早期绒毛的间质细胞来自细胞滋养
The human and primate placental villus center is a site that contains the fetal vascular bed, many connective tissue cells and macrophages (Hofbauer cells). Previous studies of sub-microstructure have focused on the development and differentiation of trophoblast cells, occasionally paying attention to the interstitial parts. Hertig examines monkey and human early pregnancy specimens and suggests that these tissues in the villus center originate from trophoblast tissue in situ delamination. This article from the rhesus monkey pregnant 16 to 60 days of placental villus take more dense specimens of the following items: (1) the source of endothelial cells and placental villi in the mechanism of angiogenesis. (2) The source of Hofbauer cells. (3) the source of stromal cytoplasmic cells. The results do not support Hertig’s early villi of stromal cells derived from cytotrophobiology
