Project description:The cardiac stroma contains multipotent mesenchymal progenitors. However, lineage relationships within cardiac stromal cells are poorly defined. Here, we identify heart-resident PDGFRa+ SCA-1+ cells as cardiac Fibro/Adipogenic Progenitors (cFAPs) and show that they respond to ischemic damage by generating SCA-1- fibrogenic cells. Pharmacological blockade of this differentiation step with an anti-fibrotic tyrosine kinase inhibitor decreases post-myocardial infarction (MI) remodeling and leads to improvement in heart function.

Project description:Aims: Resident cardiac progenitor cells show homing properties when injected into the injured but not into the healthy myocardium. The molecular background behind this difference in behavior needs to be studied to elucidate how adult progenitor cells can restore cardiac function of the damaged myocardium. Since the brain-derived neurotrophic factor (BDNF) moderates cardioprotection in injured hearts, we focused on delineating its regulatory role in the damaged myocardium. Methods and Results: Comparative gene expression profiling of freshly isolated undifferentiated Sca-1 progenitor cells derived either from heart failure transgenic αMHC-CyclinT1/Gαq overexpressing mice or wildtype littermates revealed transcriptional variations. Bdnf expression was up-regulated 5-fold during heart failure, which was verified by qRT-PCR and confirmed at the protein level. The migratory capacity of Sca-1 cells from transgenic heart was improved by 15% in the presence of 25ng/ml BDNF. Furthermore, BDNF-mediated effects on Sca-1 cells were studied via pulsed Stable Isotope Labeling of Amino acids in Cell Culture (pSILAC) proteomics approach. After BDNF treatment, significant differences between newly synthesized proteins in Sca-1 cells isolated from control and transgenic mice were observed for CDK1, SRRT, HDGF, and MAP2K3, which are known to regulate cell cycle, survival and differentiation. Moreover, BDNF repressed the proliferation of Sca-1 cells from transgenic hearts. Conclusion: Comparative profiling of resident Sca-1 cells revealed elevated BDNF levels in the failing heart. Exogenous BDNF (i) stimulated migration, which might improve the homing ability of Sca-1 cells derived from the failing heart and (ii) repressed the cell cycle progression suggesting its potency to ameliorate heart failure.

Project description:Adult mice hearts contain a population of resident mesenchymal stem cell (MSC)-like cells called cardiac colony forming units-fibroblast (cCFU-F). The cCFU-F are housed in a population of non-muscle cardiac cells that are Pdgfra+/Sca1+/Cd31- (S+P+ fraction). The goal of this experiment was to profile the heterogeneity of cell sub-types contained within the S+P+ fraction. We profiled two replicates of S+P+ single-cell transcriptomes from the cardiac ventricles of adult, male, C57BL/6J mice after FACS sorting for live Pdgfra+/Sca1+/Cd31- non-myocyte cells.

Project description:The circulating leukocyte population contains a fraction of cells derived from progenitors that had transient PDGFRa expression during embryonic development (PDGFRa-lineage). During inflammation, extravasated leukocytes in inflamed tissue modify the tissue-resident leukocyte population and crosstalk with the stromal cells. The current study investigates the effects of extravasated leukocytes derived from PDGFRa-lineage origin on the skin in atopic dermatitis (AD). Lineage- bone marrow progenitors were isolated from PDGFRa-lineage labeling mice which labels cells derived from PDGFRa-lineage with tdTomato. Progenitors derived from PDGFRa-lineage or non-PDGFRa-lineage were transplanted to irradiated EGFP-transgenic mice and allowed for bone marrow reconstitution (BMT). AD was then induced by repeated topical application of MC903 for six times. On day 14, RNA was isolated from inflamed skin to construct library for bulk RNA sequencing. AD skin transcriptomes of PDGFRa-lineage and non-PDGFRa-lineage BMTs were compared. In addition, the obtained dataset were paired with flow cytometric measurement of leukocyte extravasation to compare samples with similar extravasation loads. We found via functional enrichment analyses that extravasated PDGFRa-lineage leukocytes possess intrinsic properties that differ from non-PDGFRa-lineage, coordinate stronger inflammatory responses and modulate the extracellular matrix.

Project description:Alveolar type II cells were isolated from mice before P. aeruginosa injection (basal state) and at 72 h post-PA, and were separated into Sca-1+ and Sca-1- populations. Gene expression profile in the following four groups of cells were compared: non-PA Sca-1-, non-PA Sca-1+, 72 h post-PA Sca-1- and 72 h post-PA Sca-1+.
