Single cell RNA sequencing analysis using embryonic day 9.5 placenta from control and GATA DKO mice

Project description:The placenta establishes a maternal–fetal exchange interface which ensures transportation of nutrients and gases between the mother and the fetus. A critically conserved step in the establishment of this exchange surface in mammals is the fusion of trophoblast cells into a multinucleated syncytiotrophoblasts (SynT). In mice, SynTs develop via differentiation of the labyrinth trophoblast progenitors (LaTP) of the developing placenta, and in humans, SynTs develop via differentiation of villous cytotrophoblast (CTB) progenitors. Despite being an indispensable step for mammalian development in utero, conserved molecular mechanisms that ensure SynT development are poorly understood. Herein, we show that GATA2 and GATA3 (GATA factors) plays an essential role in labyrinth trophoblast progenitors (LaTPs) thereby committing these cells towards the SynT differentiation program. Mature syncytial layer specific immunostaining with established markers, and ultrastructure analysis of the labyrinth revealed that the loss of GATA factors was impairing the formation of mature SynT cells. We therefore focused our attention on the status of the labyrinth progenitor trophoblast cells in the GATA DKO vs the control placentae. To do that we performed single cell RNA Sequencing (scRNA-Seq) with E9.5 control and Gcm1Cre GATA KO placentae.

Gene expression changes in embryonic PECAM-1+ cells from Gata2 +9.5 enhancer targeted mice

Project description:We have generated a nonconditionall deletion of an E-box - GATA motif composite element from a putative enhancer 9.5 kb downstream of the Gata2 1S promoter. The mutation results in lethality at E13.5 to E14.5 with embryos exhibiting dectects in definitive hematopoiesis and vasculature integrity. Hematopoietic stem and progenitor cells are nearly absent from these mice and Gata2 expression is severely reduced in Pecam-1+ endothelial cells from E12.5-12.5 embryos but is expressed at normal levels in the embryonic brain. We have employed gene expression profiling in Pecam-1+ cells from wild type and Gata 2+9.5 mutant littermates to identify genes involved in maintaining vascular integrity.

RNA expression profiles of murine polyploid trophoblast giant cells (TGCs) from day 9.5 implantation sites.

Project description:We employed RNA-seq to transcriptionally profile a pure population of hand-dissected polyploid TGCs from embryonic day 9.5. These data provide a set of polyploid-specific TGCs transcripts that will aid in the understanding of TGCs differentiation and endoreplication.
