Extravillous Cytotrophoblast

Expression of the human homeobox gene HB24 in the cytotrophoblast stem cell population in rst-trimester human placenta was investigated. HB24expression was downregulated after cytotrophoblast had differentiated into syncytiotrophoblast. Expression of HB24 was also detected in rst-trimester invasive extravillous cytotrophoblast cells. In term placenta, HB24 expression was detected in residual cytotrophoblast cells and in syncytiotrophoblast. Northern analysis revealed two HB24 transcripts in rst-trimester placenta of approximately 2·5 kb and 5·3 kb. Ribonuclease protection assays were used to conrm expression of HB24 in rst-trimester and term placenta and also to provide evidence that HB24 is downregulated in choriocarcinoma cell lines. In addition to being required for differentiation of the haematopoietic cell lineage, HB24 may be required for differentiation of the extra-embryonic trophoblast cell lineage.

Syncytial Trophoblast

The alteration in membrane relationships seen at implantation include 1) interaction between cytotrophoblast cells to form syncytial trophoblast and addition to the syncytium by subsequent fusion of cytotrophoblast cells, 2) formation of a wide variety of functional complex relationships by trophoblast with uterine epithelial cells in the process of invasion of the endometrium, and 3) in the case of the rabbit, fusion of some uterine epithelial cells with the trophoblast.Formation of syncytium is apparently a membrane fusion phenomenon in which rapid confluence of cytoplasm often results in isolation of residual membrane within masses of syncytial trophoblast. Often the last areas of membrane to disappear are those including a desmosome where the cell membranes are apparently held apart from fusion.

In dogs, passive immunity is conferred to fetuses and neonates by the transfer of maternal immunoglobulin G through the placenta during the last trimester of pregnancy and via the mammary gland after parturition, respectively. However, morphological evidence of transplacental transport is still lacking. The aim of the present study was to localize maternal immunoglobulin G in the labyrinthine zone and in the haemophagous zone of the canine placenta by means of immunohistochemistry and immunocytochemistry. In the labyrinthine zone, immunoglobulin G was detected in all the layers of the materno-fetal barrier including the fetal capillaries. Immunoreactivity was particularly prominent in maternal basement membrane material as well as in the syncytiotrophoblast. However, this evidence of transplacental transport of immunoglobulin G originated from a limited number of unevenly distributed maternal vessels only. In the cytotrophoblast of the haemophagous zone, immunoglobulin G was localized to phagolysosomes at various stages but was never detected within fetal vessels. The results indicate that maternal immunoglobulin G is degraded in cytotrophoblast cells of the hemophagous zone and, therefore, that transplacental transport is restricted to a subpopulation of maternal vessels in the labyrinthine zone.
