Project description:These samples are part of a study to provide a spatially resolved single-cell multiomics map of human trophoblast differentiation in early pregnancy. Here we profiled three human implantation sites (between 6 and 9 post-conceptional weeks, PCW) with snucRNAseq; five decidual and three placental samples from 8-13 PCW by scRNA-seq/snRNA-seq.

Project description:Trophoblast Invasion is a complex mechanism that involves several genes and processes that are exquisitely regulated by the mother. Functional genomics has shown that immunomodulatory and proliferation are two essential key processes involved. Adult virgin B6CBA F1/J female mice were mated with CD1 fertile males to induce pregnancy (day 0=vaginal plug). Mice were sacrificed by cervical dislocation. Implantation and inter-implantation sites were divided by sharp dissection 6.5 days post-coitum (dpc) (n=3 mice). Uterine segments included uterine myometrium, stroma, and epithelium. Inter-implantation decidua (ID) were collected and Implantation sites also were divided by sharp dissection to separate extra-embryonic tissue (ET) from surrounding decidua (SD). From the embryo, only the invasive trophoblast formed by the ectoplacental cone was studied too.
Project description:These samples are part of a study to provide a spatially resolved single-cell multiomics map of human trophoblast differentiation in early pregnancy. Here we profiled with 10x Visium Spatial transcriptomics of the entire maternal-fetal interface including the myometrium, allowing us to resolve the full trajectory of trophoblast differentiation.
Project description:RNA sequencing of macrophages and monocytes from first-trimester human decidua basalis (decB), decidua parietalis (decP), and placenta
Project description:The goal of this study was to transciprtionally profile the three layers of the human placenta (decidua, fetal membrane and placental villi) from the mid-gestation healthy human placenta.
Project description:This SuperSeries is composed of the following subset Series: GSE22187: Changes in gene expression in implantation sites by absence of Cbs GSE22189: Changes in gene expression in inter-implantation sites by absence of Cbs Refer to individual Series
Project description:The placenta is considered one of the candidate cell sources in cellular therapeutics because of a large number of cells and heterogenous cell population with myogenic potentials. We first analyzed myogenic potential of cells obtained from six parts of the placenta, i.e., umbilical cord, amniotic epithelium, amniotic mesoderm, chorionic plate, villous chorion (chorion frondosum), , and decidua basalis. Implantation of placenta-derived cells into dystrophic muscles of immunodeficient mdx mice restored sarcolemmal expression of human dystrophin. Co-existence of human and murine nuclei in one myotube and presence of human dystrophin in murine myotube suggests that human dystrophin expression is due to cell fusion between host murine myocytes and implanted human cells. In vitro analysis revealed that cells derived from amniotic mesoderm, chorionic plate, ,and villous chorion efficiently transdifferentiate into myotubes. These cells fused to C2C12 murine myoblasts by in vitro co-culturing, and murine myoblasts start to express human dystrophin after fusion. These results demonstrate that placenta-derived cells, especially extraembryonic mesodermal cells, have a myogenic potential and regenerative capacity of skeletal muscle. Determination of cell specification with the gene chip analysis revealed that each placental cell has a distinct expression pattern. Keywords: Determination of cell specification
