(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) 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) Fibro-Adipogenic Progenitors (FAPs) are currently defined by their anatomical position, expression of non-specific membrane-associated proteins, ability to adopt multiple lineages and to perform different biological activities in response to physiological or pathological stimuli. Gene expression analysis at single cell level revealed the intrinsic heterogeneity of FAPs and uncovered discrete subpopulations (subFAPs), which can be prospectively isolated by FACS, based on the expression levels of Tie2 and Vcam1. more...

(Submitter supplied) Wagyu cattle are renowned for their premium beef characterized by abundant intramuscular fat (IMF). In contrast, Brahman, a popular breed in the southern coastal area of the US, generally produces tough meat with scarce IMF. However, the mechanisms underlying the differential meat quality between the two breeds are still largely unknown. Using single-cell RNAseq (scRNAseq), we identified many tissue-resident and immune cell types in Wagyu, Brahman, and Wagyu/Brahman crossbred cattle muscle. 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) Fibro-adipogenic progenitors (FAPs) are emerging cellular components of the skeletal muscle regenerative environment. The alternative functional phenotype of FAPs - either supportive of muscle regeneration or promoting fibro-adipogenic degeneration – is a key determinant in the pathogenesis of muscular diseases, including Duchenne Muscular Dystrophy (DMD). However, the molecular regulation of FAPs is still unknown. more...

(Submitter supplied) Fatty infiltration, the ectopic deposition of adipose tissue within skeletal muscle, is mediated via the adipogenic differentiation of fibro-adipogenic progenitors (FAPs). We used single-nuclei and single-cell RNA sequencing to characterize FAP heterogeneity in patients with fatty infiltration. We identified an MME+ FAP subpopulation which, based on ex vivo characterization as well as transplantation experiments, exhibits high adipogenic potential. more...

(Submitter supplied) We investigated the transcriptome of cell states identified in fibro/adipogenic progenitors (FAPs) isolated from mdx mice using as a criterion SCA-1 expression. We found that after 5 days in growth medium FAP cell states have different transcriptomes. In particular, among the "Biological process" GO terms enriched in genes up-regulated in SCA1-High-FAPs we found genes correlated with adipogenic differentiation. more...

(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 and fat replacement in the skeletal muscle is a major complication that leads to a loss of mobility in chronic muscle disorders, such as muscular dystrophy. However, our current knowledge on the in vivo properties of adipogenic stem and precursor cells remains unclear, mainly due to the high cell heterogeneity in skeletal muscles. For this purpose, we used single-cell RNA-sequencing to decomplexify interstitial cell populations in healthy and dystrophic skeletal muscles. more...

(Submitter supplied) In vertebrates, activation of innate immunity is an early response to injury, implicating it in the regenerative process. However, the mechanisms by which innate signals might regulate stem cell functionality are unknown. Here we demonstrate that type 2 innate immunity is required for regeneration of skeletal muscle after injury. Muscle damage results in rapid recruitment of eosinophils, which secrete IL-4 to activate the regenerative actions of muscle resident fibro/adipocyte progenitors (FAPs). more...

(Submitter supplied) The purpose of this study is to investigate how immune cells (macrophages) are closely linked with fibro-adipogenic progenitors (FAPs) during recovery processe. We report that the depletion of Mrc1+ (gene encoding CD206) M2-like macrophages promoted the recovery of muscle after injury. A total RNA sequence analysis of whole muscle or isolated FAPs revealed that the depletion of Mrc1+ M2-like macrophages resulted in the activation of FAPs. more...
