ABSTRACT: Here, we performed single cell RNA sequencing (scRNA-seq) of human fetal kidney tissue samples from 2 individual biological specimens (13.7 and 15.4 weeks gestation). The data set is composed of approximately 10,000 cells from diverse renal lineages. Lineages captured include nephron progenitors, epithelium, stroma, immune, and endothelium.
Project description:Here, we performed single cell RNA sequencing (scRNA-seq) of human fetal duodenal tissue samples from 8 individual biological specimens across 7-21 weeks of gestation. The data set is composed of over 37,000 cells (between 3,000-9,000 cells per time point) from diverse intestinal lineages. Lineages captured include epithelium, mesenchyme, immune, neurons, and endothelium. These data were used to specifically interrogate the development and emergence of mesenchymal lineages during human development.
Project description:Here, we present the fetal mouse intestine data from the project \\"Comparison of human and mouse mesenchyme identifies common and unique aspects of intestinal patterning\\". Whole intestines were harvested from fetuses from timed pregnant matings for wildtype C57BL/6 mice (Jax strain #000664). Fetal stages were confirmed according to the Theiler staging chart (https://www.emouseatlas.org/emap/ema/staging_criteria/staging_criteria.html). Whole intestines (from the common bile duct through the cecum) were collected at key stages of development (E13.5, E14.5, E15.5, E16 and E17.5). Male and female intestines from each stage were pooled and dissociated to single cells for single cell RNA sequencing as previously described (Miller et al. 2020 Dev Cell). Specifically, E13.5 was 6 intestines, E14.5 was 5 intestines, E15.5 was 4 intestines, E16 was 3 intestines and E17.5 was 3 intestines.
Project description:Here, we used single cell RNA-sequencing (scRNA-seq) to profile pluripotent stem cell derived human definitive endoderm and intestinal organoids (HIOs) at several timepoints of in vitro growth (7, 14, and 28 days) and after in vivo growth beneath the kidney capsule of a murine host (4 and 8 wks post-transplant). Additionally, we profiled HIOs grown in a non-adhesive alginate hydrogel and also CDX2 knockout HIOs. In order to benchmark the organoid cultures, we used scRNA-seq to profile primary human fetal esophagus (14.3 pcw, 16.7 pcw), stomach (6.7, 14.3, and 16.7 pcw), liver (14.4 pcw), small intestine ( 11.4 and 14.4 pcw) and colon (11.4, 14.4, and 18.9 pcw). Diverse cell lineages were captured across all tissues profiled, including: epithelium, mesenchyme, neurons, endothelium, and immune lineages.
Project description:Here, we performed single-cell RNA sequencing (scRNA-seq) of a human fetal jejunum tissue sample from 1 individual biological specimen age 40 weeks post conception. The data set is composed of cells from diverse intestinal lineages.
Project description:Here, we performed single cell RNA sequencing (scRNA-seq) of human fetal ileum tissue samples from 3 individual biological specimens ages 11.4, 14.4, and 18.9 weeks post conception. The data set is composed of over 16,000 cells from diverse intestinal lineages.
Project description:Here, we performed single cell RNA sequencing (scRNA-seq) of 1 (one) human fetal lung tissue specimen (18.9 week) and 2 (two) human fetal intestine specimens (12.1 and 18.9 week) (total of 3 (three) independent biological specimens). The data set is composed of approximately 5,000 lung cells and 7,500 intestine cells. Lineages captured across both tissues include but are not limited to epithelium, stroma, immune, neurons and endothelium.
Project description:Here, we used single cell RNA-sequencing (scRNA-seq) to profile pluripotent stem cell derived human intestinal organoids (HIOs) grown in matrigel or a non-adhesive alginate hydrogel after 28 days of in vitro growth. Additionally, we used scRNA-seq to profile HIOs derived in the presence of Neuregulin 1 (NRG1) and/or EGF after 40 days of in vitro growth.
Project description:Underdeveloped lungs are a primary cause of morbidity and mortality in premature infants, but our ability to help these patients by speeding up lung development are hindered by a lack of understanding of human lung developmental biology. Here, we performed single cell RNA sequencing of the human fetal lung from samples spanning from 11.5 weeks gestation to 21 weeks gestation from the distal lung, middle airways, and the tracheal epithelium. The primary goal of this experiment was to define fetal cell states to serve as a gold standard for pluripotent stem cell-derived lung cells and tissues, and to identify potential signaling pathways that drive differentiation of lung progenitor cells to mature cell types. Additionally, we generated bud tip progenitor organoids from 12 week human fetal lung bud tip progenitors. We show that treatment of bud tip progenitor organoids with a short pulse of dual SMAD activation (BMP4+TGFb1) led to the upregulation of lung basal cell markers, a cell type that serves as a critical stem cell for the adult airway, and that further treatment with dual SMAD inhibition leads to the generation of airway-like organoids containing differentiated cell types of the adult airway, including basal stem cells.
Project description:Here, we used single cell RNA-sequencing (scRNA-seq) to profile 13-week post-conception distal human fetal lung explants cultured in an air liquid interface system and treated with an LGR5 ectodomain adenovirus that inhibits R-Spondin function or control adenovirus. A third, non-infected, condition was also sequenced. We also performed scRNA-seq on distal human fetal lung tissue from an 8.4-week post-conception biological specimen. Diverse cell lineages were captured in all data sets, and include epithelium, mesenchyme, immune, neurons, and endothelium.
Project description:Here, we used single-cell RNA-sequencing (scRNA-seq) to profile pluripotent stem cell derived human intestinal organoids (HIOs) grown in an alginate matrix after 3, 7, and 14 days of in vitro growth. Samples were grown in minigut media supplemented with either ENR or EGF.
