Project description:To investigate the gene regulatory mechanisms driving T cell development, we generated single-cell transcriptomics and chromatin accessibility data from a human fetal thymus sample at 10 weeks of gestation.

Project description:The Human Developmental Biology Resource (HDBR) expression resource is a new resource for studying prenatal human brain development. It consists of two parts which have been uploaded as two submissions: HDBR expression resource- RNAseq (E-MTAB-4840, this submission) and HDBR expression resource- SNP data (E-MTAB-4843). It is unique in the age range (4 post conception weeks [PCW] to 17PCW) and number of brains studied, particularly those under 8PCW. It is also unique in that both the large-scale data sets and the corresponding RNA and DNA samples are available, the latter via the MRC-Wellcome Trust Human Developmental Biology Resource (HDBR; http://www.hdbr.org). There are 628 RNA-seq datasets from different regions of the brains studied. The number of regions depends on the stage and size of the sample and/or the tissue available. Embryos (4-8PCW) have been staged using a modified Carnegie staging system, details can be found at http://database.hudsen.eu/. All the RNAseq datasets from the same brain have the same embryo/fetus number (e.g. RNAseq datasets HDBR251-HDBR254 are from different tissues from embryo number 1406). The embryo/fetus ID number is recorded in the individual column. The majority of the brains studied are between 4 and 12PCW. During this time the major brain regions are established and there are the early stages of cortex development. DNA was prepared from all the tissues used for RNA-seq analysis and SNP genotype data generated from one tissue from each brain. RNA-seq data and SNP-data from the same tissue and brain have the same name (e.g. HDBR469). There are also SNP genotype data from 229 additional specimens in paraffin wax blocks available for individual gene expression studies. These data are in the accompanying HDBR expression resource- SNP data (E-MTAB-4843).
Project description:Here, we performed multiome sequencing (snRNA-seq + snATAC-seq) of human fetal liver samples from 3 trisomy 21 (Ts21) and 3 healthy foetuses (median age 14 post-conception weeks). The data set is composed of approximately 60,000 CD45+ foetal liver cells.
Project description:This resource comprises a single-cell multi-lineage map of first trimester infected placental cells. We have included data from both uninfected cells and cells infected with three pathogens known to cause maternal and fetal disorders: Plasmodium falciparum, Listeria monocytogenes, and Toxoplasma gondii. We also generated single-nuclei map of infected trophoblasts and their corresponding controls. Furthermore, we created a single-nuclei reference dataset containing information from uninfected primary placental organoids as well as organoids infected with P. falciparum. Additionally, we conducted sequencing at a single-cell level for P. falciparum parasites that were bound to the placenta (pf_b), parasites unbound to the placenta (pf_nb), and parasites that were cultured in vitro (pf_iv).
Project description:Here, we performed single cell RNA sequencing (scRNA-seq) of human fetal liver and bone marrow tissue samples from 15 trisomy 21 (Ts21) and 3 healthy foetuses (median age 14 post-conception weeks). The data set is composed of approximately 1.1 million cells from three different populations: CD235- (niche and haematopoietic cells depleted of erythrocytes), CD34+/Lin- (haematopoietic progenitors), and CD45+ (all haematopoietic cells).
Project description:Using single-cell RNAseq (scRNAseq) and paired VDJ analysis, we create the first comprehensive cell atlas of the healthy developing, paediatric and adult human gut, including 347,980 cells from up to 10 distinct anatomical sites. We use this data to trace the cellular composition of the gut throughout life, define novel cell markers and cell-cell interactions. We find four neuronal cell populations in the developing enteric nervous system, with expression patterns indicative of irritable bowel syndrome and Hirschsprung’s disease, and identify key cell players and communication networks initiating lymphoid structure formation in early human development.
