Deportation of syncytial sprouts from the term human placenta.
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.
