scRNAseq datasets supporting a common precursor expression program leading to brain pericyte differentiation from neural crest and mesoderm

Project description:Brain pericytes are critical for regulating endothelial barrier function and activity, thus ensuring adequate blood flow to the brain. How the developmental acquisition of pericytes to naked endothelium is regulated, is largely unknown, but is relevant to disorders where vessels are poorly stabilized. Although pericytes are derived from neural crest and mesoderm, brain pericytes from both origins are currently indistinguishable; the genetic pathways leading to a convergent pericyte phenotype are unknown. We show here that a precursor population expressing the transcription factor nkx3.1 with origins in both NCC and mesoderm, develops into brain pericytes. We identify the gene signature of these precursors and show that an nkx3.1, foxf2a, and cxcl12b -expressing pericyte precursor population is present around the cxcr4 expressing basilar artery, and that these cells later spread throughout the brain. Cxcl12b- Cxcr4 signaling is required for pericyte attachment and differentiation but not for later pericyte development. Further, both nkx3.1 and cxcl12b are necessary and sufficient in regulating pericyte number. Thus, we have defined an undescribed population of pericyte precursors and identified genes critical for their differentiation.

A common precursor expression program leading to brain pericyte differentiation from neural crest and mesoderm

Project description:Brain pericytes are one of the critical cell types that regulate endothelial barrier function and activity, thus ensuring adequate blood flow to the brain. The genetic pathways guiding undifferentiated cells into mature pericytes are not well understood. We show here that pericyte precursor populations from both neural crest and head mesoderm of zebrafish express the transcription factor nkx3.1 develop into brain pericytes. We identify the gene signature of these precursors and show that an nkx3.1-, foxf2a-, and cxcl12b-expressing pericyte precursor population is present around the basilar artery prior to artery formation and pericyte recruitment. The precursors later spread throughout the brain and differentiate to express canonical pericyte markers. Cxcl12b-Cxcr4 signaling is required for pericyte attachment and differentiation. Further, both nkx3.1 and cxcl12b are necessary and sufficient in regulating pericyte number as loss inhibits and gain increases pericyte number. Through genetic experiments, we have defined a precursor population for brain pericytes and identified genes critical for their differentiation. This SuperSeries is composed of the SubSeries listed below.

Single cell gene expression of early E8.5 pioneer neural crest cells and paraxial mesoderm

Project description:Laser capture microdissection (LCM) was used to isolate cells from the principal critical micro-regions, whose development, differentiation and signaling interactions are responsible for the construction of the mammalian face. At E8.5, as migrating neural crest cells begin to exit the neural fold/epidermal ectoderm boundary, we examined the facial mesenchyme, composed of neural crest and paraxial mesoderm cells, as well as cells from adjacent neuroepithelium We performed single cell studies to better define the gene expression states of the early E8.5 pioneer neural crest cells and paraxial mesoderm, and present microarray data detailing expression patterns within these embryonic cell populations. Mouse emrbyos were harvested at developmental stage E8.5 and single cells were captured from the neuroepithilium, neural crest, and paraxial mesoderm. RNA was extracted, labelled, and quantified using the Mouse ST-l microarray.

Origin of Ewing sarcoma by embryonic reprogramming of neural crest to mesoderm

Project description:Ewing sarcoma is a malignant small round blue cell tumor of bones and soft tissues, predominantly affecting children, adolescents and young adults. Ewing sarcoma is caused by chromosomal translocations that generate aberrant chimeric transcription factors, most frequently EWSR1::FLI1. Ewing sarcomas exhibit features of both neural and mesenchymal cells. The cell of origin of Ewing sarcoma and the mechanisms of EWSR1::FLI1-driven cell transformation are the subjects of long-standing debates, largely due to the absence of a representative animal model. By developing a robust Ewing sarcoma model in zebrafish, we provide evidence for a neural crest origin of this cancer. We show that neural crest-derived cells (NCCs) uniquely tolerate expression of the human EWSR1::FLI1 oncofusion protein in vivo and that targeted expression of the oncofusion in NCCs is sufficient to generate Ewing sarcoma tumors. In the trunk, EWSR1::FLI1 reprogrammed NCCs to a mesoderm-like state, including upregulation of the early mesoderm specifier tbxta (Brachyury/T) and mesenchymal genes pdgfra, twist1a, and prrx1a. Mesodermal reprogramming of trunk neural crest was evident by the ability of EWSR1::FLI1-expressing cells to induce ectopic fins throughout the body. Single-nucleus analysis of RNA expression and chromatin accessibility, combined with genome-wide profiling of EWSR1::FLI1 binding, revealed that EWSR1::FLI1 targets single GGAA-containing ETS sites in mesodermal developmental enhancers for neural crest to mesoderm reprogramming during cancer initiation, also binding to GGAA repeats in established tumors. These findings show that EWSR1::FLI1 hijacks normal ETS-dependent developmental pathways in embryonic NCCs to drive initiation of Ewing sarcoma.
