摘要利用氚化胸苷放射自显影研究了部分人胎盘组织。细胞滋养细胞、绒毛间质和血管内皮细胞均能摄取胸苷，但合体滋养细胞不摄取。这一发现表明，在孕龄14-18周的人胎盘中，合体滋养层的无丝分裂在这一细胞层的形成中并不起重要作用。
Summary Portions of human placental tissue have been studied by radioautography utilizing tritiated thymidine. Thymidine uptake could be demonstrated in cytotrophoblast, villous mesenchyme and vascular endothelium but not in the syncytiotrophoblast. This finding suggests that amitotic division of the syncytiotrophoblast does not play a prominent role in the derivation of this cellular layer in the human placenta of 14-18 weeks gestational age.
