(Submitter supplied) The platelet-derived growth factor receptor alpha (PDGFRα) exhibits divergent effects in skeletal muscle. At physiological levels, signaling through this receptor promotes muscle development in growing embryos and proper angiogenesis in regenerating adult muscle. However, either increased PDGF ligands or enhanced PDGFRα pathway activity causes pathological fibrosis. This excessive collagen deposition, which is seen in aged and diseased muscle, interferes with proper muscle function and limits the effectiveness of gene- and cell-based therapies for muscle disorders. more...

(Submitter supplied) Fibrosis is a deleterious invasion of tissues associated with many pathological conditions, such as Duchenne muscular dystrophy (DMD) for which no cure is at present available for its prevention or its treatment. Fibro-adipogenic progenitors (FAPs) are resident cells in the human skeletal muscle and can differentiate into myofibroblasts, which represent the key cell population responsible for fibrosis. more...

(Submitter supplied) Obesity-induced white adipose tissue (WAT) fibrosis is believed to accelerate WAT dysfunction. However, the cellular origin of WAT fibrosis remains unclear. We showed that adipocyte platelet-derived growth factor receptor-a-positive (PDGFRa+) progenitors adopt a fibrogenic phenotype in obese C3H/HeOuJ (C3H) mice prone to visceral WAT fibrosis. Two progenitor populations could be distinguished in the epididymal white adipose tissue (EpiWAT) of lean C3H mice, based on CD9 expression. more...

(Submitter supplied) Obesity-induced white adipose tissue (WAT) fibrosis is believed to accelerate WAT dysfunction. Two progenitor populations could be distinguished in omental white adipose tissue (oWAT) of morbidly obese individuals based on CD9 expression. In addition, the frequency of CD9high progenitors in oWAT correlates with oWAT fibrosis level, insulin-resistance severity and type 2 diabetes. To further gain insight into the functional differences between the CD9high and CD9low progenitor subsets, we performed transcriptomic profiling of FACS-sorted progenitor populations isolated from oWAT of obese individuals. more...

(Submitter supplied) Analysis of Nestin-GFP+ pericytes flow sorted from 3-day-old mouse cutaneous adipose tissue, comparing controls with wild type PDGFRa, and mutants with increased PDGFRa signaling driven by a Cre/lox-inducible D842V knockin mutation in the PDGFRa kinase domain. The control cells have adipogenic properties in vitro or when transplanted subcutaneously into recipient mice. The D842V mutant cells show altered behavior in the same assays, with poor adipogenic differentiation but a propensity to transition into profibrotic cells that secrete collagen

(Submitter supplied) PDGFRα+ cells are interstitial/perivascular mesenchymal progenitor cells that have been associated with fibro-adipogenic processes. However, their function during tissue homeostasis or in response to revascularization and regeneration stimuli remains to be fully defined. Here, by high-throughput transcriptomic analysis, adoptive transfer and multicolor lineage tracking we showed that PDGFRα+ cells from skeletal muscle cluster as a population that is transcriptionally distinct from other mesenchymal stromal cells and with an essential role in tissue revascularization and restructuring of ischemic areas. more...

(Submitter supplied) Injured skeletal muscle regenerates, but with age or in muscular dystrophies, muscle is replaced by fat. Upon injury, muscle-resident fibro/adipogenic progenitors (FAPs) proliferated and gave rise to adipocytes. These FAPs dynamically produced primary cilia, structures that transduce intercellular cues such as Hedgehog (Hh) signals. Genetically removing cilia from FAPs inhibited intramuscular adipogenesis, both after injury and in a mouse model of Duchenne muscular dystrophy. more...

(Submitter supplied) Utilizing glycerol intramuscular injections in M. musculus provides a model of skeletal muscle damage followed by skeletal muscle regeneration. In particular, glycerol-induced muscle injury triggers accute activation of muscle Fibro/Adipogenic Progenitors, also called FAPs. However, aging dramatically impairs FAP function. We characterized genome-wide expression profiles of young and old FAPs in the non-proliferative and activated state, freshly isolated to non-injured or damaged muscles, respectively. more...

(Submitter supplied) Hepatic stellate cell autophagy inhibits extracellular vesicle release to attenuate liver fibrosis. Primary human hepatic stellate cells were treated with PDGF or PDGF + SHP2 inhibitor. RNA was purified and submitted for sequencing to Mayo Clinic Genomics Core. After applying the filters FDR>0.05, Log2(FC)>1 and RPKM>15, we ended up with nearly 300 genes differentially regulated between the two conditions. more...

(Submitter supplied) Adipocytes arise from commitment and differentiation of adipose precursors in white adipose tissue (WAT). In studying adipogenesis, precursor markers, including Pref-1 and PDGFRα, are used to isolate precursors from stromal vascular fraction of WAT, but the relationship among the markers is not known. Here, we used Pref-1 promoter-rtTA system in mice for labeling Pref-1+ cells and for inducible inactivation of Pref-1 target, Sox9. more...
