Single-cell RNA sequencing of human peripheral blood progenitors captures early mast cell differentiation

Project description:Activation of mast cells through FcεRI can result in allergic responses. The identity of mast cells progenitors is controversial, in particular whether these cells express FcεRI. Here, we performed single-cell RNA sequencing of human peripheral blood progenitors to study the appearance of FcεRI during hematopoietic progenitor differentiation.

Expression data from human mast cell progenitors and mature basophils

Project description:CD34+ CD117+ cells in human peripheral blood have mast cell-forming capacity. We have identified highly committed mast cell progenitors as Lin- CD34+ CD117 intermediate/high FcεRI+ cells. To explore the gene expression profile of the highly committed mast cell progenitors, we performed whole-transcriptome microarray analyses of the cells and compared them with mature basophils.

Expression data from mouse mast cell progenitors, mature mast cells and innate lymphoid cells of type 2

Project description:Mast cells originate from the bone marrow and develop into c-kit+ FcεRI+ cells. As both mast cell progenitors and mature mast cells express these cell surface markers, ways validated to distinguish between the two maturation forms with flow cytometry have been lacking. We identified and sorted two distinct populations of mast cells from mouse peritoneum. Gene expression microarray analyses were used to confirm the maturation statuses of the mast cell populations.

E-cadherin marks the early commitment of murine hematopoietic progenitors to the basophil and mast cell fate

Project description:E-cadherin is a calcium-dependent cell-cell adhesion molecule extensively studied for its involvement in tissue formation, epithelial cell behavior and suppression of cancer; however its expression in the hematopoietic system hasn't received much attention. Combining single-cell RNA sequencing analyses and immunophenotyping, we revealed expression of E-cadherin in the basophil and mast cell lineages. No defect in basophil and mast cell differentiation was observed in mice lacking E-cadherin in the hematopoietic system, supporting that E-cadherin is not required per se for basophil and mast cell differentiation. Yet, we evidenced that granulocyte-monocyte progenitors expressing high levels of E-cadherin have an enriched capacity to differentiate into basophils and mast cells. Importantly, E-cadherin expression is observed on committed progenitors prior to the expression of other reported markers of these lineages. We named those progenitors pro-BMPs (pro- basophil and mast cells progenitors). Using RNA-sequencing, we demonstrated the transcriptional priming of pro-BMPs to the basophil and mast cell lineages.

Adult Connective Tissue-Resident Mast Cells Originate from Late Erythro-Myeloid Progenitors [development]

Project description:Purpose: The purpose is to systemically identify RNA expression changes along mast cell development during embryogenesis. Methods: We profiled RNA-seq in early EMPs and their progeny. Results: Fetal MCPs acquire the mast cell-specific gene signature from E11.5 and complete their maturation in peripheral tissues.

Human connective tissue mast cell proteome

Project description:Mast cells are hematopoietic cells that reside preferentially in tissues exposed to internal and external environments. Mast cells sense immunological, inflammatory and environmental stimuli, and can be activated to release granules and generate inflammatory mediators. Mast cell-derived products confer protection against snake venoms and some parasite infections. Aberrant activation of mast cells is a major contributor to human pathology, including allergy, asthma and adverse drug reactions. Their strict tissue location has largely impeded the isolation of large numbers of primary mast cell for further analysis. To better understand the biology of mast cells, we analyzed the proteome of primary human and mouse mast cells by quantitative mass spectrometry. We identified a mast cell-specific protein signature that was conserved from mouse to man. Compared to a comprehensive set of other immune cell lineages, proteome analysis identified a unique and distant mast cell cluster. The mast cell signature included proteins governing granule biosynthesis and secretion, as well as proteoglycan- and neurotransmitter metabolism. Proteome conservation across species suggests evolutionary maintenance of mast cell functions.

Class IA PI3Kinase regulatory subunit p85α regulates mast cell growth and survival related genes

Project description:Stem cell factor (SCF) mediated KIT receptor activation plays a pivotal role in mast cell growth, maturation and survival. However, the signaling events downstream from KIT are poorly understood. Mast cells express multiple regulatory subunits of class 1A PI3Kinase (PI3K) including p85α, p85β, p50α, and p55α. While it is known that PI3K plays an essential role in mast cells; the precise mechanism by which these regulatory subunits impact specific mast cell functions including growth, survival and cycling are not known. We show that loss of p85α impairs the growth, survival and cycling of mast cell progenitors (MCp). To delineate the molecular mechanism (s) by which p85α regulates mast cell growth, survival and cycling, we performed microarray analyses to compare the gene expression profile of MCps derived from WT and p85α-deficient mice in response to SCF stimulation. We identified 151 unique genes exhibiting altered expression in p85α-deficient cells in response to SCF stimulation compared to WT cells. Functional categorization based on DAVID bioinformatics tool and Ingenuity Pathway Analysis (IPA) software relates the altered genes due to lack of p85α to transcription, cell cycle, cell survival, cell adhesion, cell differentiation, and signal transduction. Our results suggest that p85α is involved in mast cell development through regulation of expression of growth, survival and cell cycle related genes. Two-condition experiment, wildtype vs. p85α-deficient mast cell progenitors stimulated with SCF. Biological replicates: 3 wildtype replicates, 3 p85α-deficient replicates.
