Acquisition of alveolar fate and differentiation competence by human fetal lung epithelial progenitor cells

ABSTRACT: Our data show that Wnt and FGF signalling, and the downstream transcription factors NKX2.1 and TFAP2C, promote human alveolar or airway fate respectively. Moreover, we have functionally validated cell-cell interactions in human lung alveolar patterning. We show that Wnt signalling from differentiating fibroblasts promotes alveolar type 2 cell identity, whereas myofibroblasts secrete the Wnt inhibitor, NOTUM, providing spatial patterning. Our organoid system recapitulates key aspects of human lung development allowing mechanistic experiments to determine the underpinning molecular regulation.

The human gastrointestinal tract through space and time- Fetal Spatial transcriptomics

Project description:Single-cell RNAseq (scRNAseq) and paired VDJ analysis and spatial transcriptomics, 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.

Single cell RNA-seq of human breast skin cells

Project description:Cells were generated for a single cell atlas of adult human skin to dissect the cellular and molecular organisation underpinning human skin immune barrier function. Surplus skin from breast reconstruction surgery was collected (n=3), then the top 200 μm layer was taken. Epidermis was separated from the dermis, and both layers were separately digested. Single cells were FACS sorted into eight categories, then loaded onto a 10x Genomics Chromium Controller, and sequenced on an Illumina HiSeq 4000.

Expression data of mESCs differentiated into Paraxial mesoderm

Project description:Stem cell-derived tissues have wide potential for modelling developmental and pathological processes as well as cell-based therapy. However, it has proven difficult to generate several key cell types in vitro, including skeletal muscle. In vertebrates, skeletal muscles derive during embryogenesis from the presomitic mesoderm (PSM). Using PSM development as a guide, we establish conditions for the differentiation of monolayer cultures of mouse embryonic stem (ES) cells into PSM-like cells without the introduction of transgenes or cell sorting. We differentiated mouse ESCs in serum-free medium supplemented with Rspo3 ( or as an alternative with Chir 9902) and the Bmp inhibitor LDN193189. In vivo, the PSM cells are first expressing Msgn1 (posterior PSM marker) and then mature to express Pax3 (anterior PSM marker). After 4 days of differentiation of mESCs, Msgn1-positive cells were FACS-sorted and their transcriptome analyzed. After 6 days of differentiation, Pax3-positive cells were sorted and their transcriptome analyzed. Mouse ESCs differentiated for 0, 4 and 6 days in serum-free medium containing a Wnt activator, a BMP inhibitor and DMSO, to study paraxial mesoderm in vitro

Human and marmoset trophoblast stem cells differ in signalling requirements and recapitulate divergent modes of trophoblast invasion

Project description:We derive experimental conditions for the derivation of marmoset trophoblast like cells. Marmoset naïve PSC form extraembryonic mesoderm in human TSC conditions, whilst TGFβ/NODAL, FGF/ERK and WNT signalling control marmoset peri- and postimplantation trophoblast identity.

Differential Gene Expression between MCF10A and MCF7 cells

Project description:These RNA-seq data were generated to correlate with genomic interaction data in a related Hi-C analysis. MCF10A is a normal-like mammary epithelial cell line and MCF7 is a transformed estrogen responsive breast cancer cell line derived from a metastatic site; both are commonly used in models of breast cancer progression. Analysis revealed a set of genes related to repression of WNT signalling that were both up-regulated in MCF7 and located in genomic regions that had transitioned from closed to open structure in MCF7. RNA-seq of MCF10A and MCF7 cells. 3 replicates each. Sequencing was strand-specific and conducted on ribo-depleted RNA.

A Multi-omic Atlas of Human Embryonic Skeletal Development -Multiome GEX+ATAC

Project description:Two distinct and anatomically restricted modes of ossification, which are endochondral ossification and intramembranous ossification, govern osteogenesis and joint formation throughout the human skeleton and, to our knowledge, the cellular bases by which they form and mature remain incompletely described in human development at single-cell resolution. To address this, we apply single-nuclei paired RNA and ATAC sequencing to decipher the molecular gene regulatory programmes that mediate maturation of the distinct bone and joint-forming niches in the cranium and appendicular skeleton across space and time from 5-11 PCW.

Comparative genomic profile of human brain microvascular endothelial cells upon TWEAK or TNFα stimulation at 3h, 12h, and 24h

Project description:The molecular mechanisms playing a role in TWEAK versus TNFɑ signaling on cerebral microvascular endothelial cells are not well defined. Therefore, we aimed to identify gene expression changes in cultures of human brain microvascular endothelial cells (hCMEC/D3) to address changes initiated by TWEAK exposure. Although related, these two cytokines mediated different effects on gene expression and on canonical pathway activation. We used Agilent Whole Human Genome Microarray 4X44K to compare TWEAK- and TNFɑ-mediated changes in gene expression after 3h, 12h, and 24h incubation of these cytokines.
