Project description:The human placenta plays vital roles in ensuring a successful pregnancy. Despite the growing body of knowledge about its cellular compositions and functions, however, there has been limited research on the heterogeneity of the billions of nuclei within the syncytiotrophoblast (STB), a multinucleated entity primarily responsible for placental function. Here, we conducted integrated snRNA-seq and snATAC-seq on human placentas from early and late pregnancy. Our findings demonstrate the dynamic heterogeneity and developmental trajectories of STB nuclei and their presence in human trophoblast stem cells (hTSCs)-derived STB. Furthermore, we identified transcription factor (TF) motifs that are biased towards diverse STB nuclear lineages through their associated gene regulatory networks. The role of these TFs in STB differentiation were confirmed in the hTSCs- and trophoblast organoid-derived STB. Together, our data provide valuable insights into the heterogeneity of human STB and represents a valuable resource for interpreting its associated pregnancy complications.

Inefficient development of syncytiotrophoblasts in the <i>Atp11a</i>-deficient mouse placenta.

Project description:The P4-ATPases ATP11A and ATP11C function as flippases at the plasma membrane to translocate phosphatidylserine from the outer to the inner leaflet. We herein demonstrated that Atp11a-deficient mouse embryos died at approximately E14.5 with thin-walled heart ventricles. However, the cardiomyocyte- or epiblast-specific Atp11a deletion did not affect mouse development or mortality. ATP11C may have compensated for the function of ATP11A in most of the cell types in the embryo. On the other hand, Atp11a, but not Atp11c, was expressed in the mouse placenta, and the Atp11a-null mutation caused poor development of the labyrinthine layer with an increased number of TUNEL-positive foci. Immunohistochemistry and electron microscopy revealed a disorganized labyrinthine layer with unfused trophoblasts in the Atp11a-null placenta. Human placenta-derived choriocarcinoma BeWo cells expressed the ATP11A and ATP11C genes. A lack of ATP11A and ATP11C eliminated the ability of BeWo cells to flip phosphatidylserine and fuse when treated with forskolin. These results indicate that flippases at the plasma membrane play an important role in the formation of syncytiotrophoblasts in placental development.
