Deportation of syncytial sprouts into the maternal circulation during early pregnancy is a well-accepted phenomenon. Whether the process continues throughout pregnancy has been more contentious. This study aimed to resolve the question through the study of serial sections derived from 5 normal term placentas. In each case, sprouts containing euchromatic nuclei were observed in the intervillous space, clearly detached from neighbouring villi. Deportation of sprouts therefore continues until term.
在妊娠早期，合胞体芽突被驱逐到母体循环中是一种被广泛接受的现象。然而，这个过程是否会持续整个孕期一直存在争议。本研究旨在通过对 5 例正常足月胎盘的连续切片研究来解决这个问题。在每种情况下，都可以在绒毛间隙中观察到含有常染色质核的芽突，明显与邻近的绒毛分离。因此，芽突的驱逐会持续到足月。
