β3‑adrenergic receptor agonist improves recovery after volumetric muscle loss and is associated with increased intramuscular brown/beige adipogenic activity in mice

Abstract Background Volumetric muscle loss (VML) often results in chronic muscle weakness, limb dysfunction, and even permanent disability. Current research primarily focuses on cell and extracellular matrix transplantation, but there is a lack of studies on the physiologically s...

Heterogeneous human muscle fibroadipogenic progenitors include a DLK1 + subpopulation that prevents fatty infiltration after injury

Fatty infiltration and fibrosis drive poor outcomes after chronic muscle injury. Here, we characterized fibroadipogenic progenitor cell (FAP) subpopulations from healthy and injured human rotator cuff muscle by single-cell RNA sequencing, full-spectrum flow cytometry, and functio...

Phenotypic divergence in rotator cuff tear and volumetric muscle loss mouse models following fibroadipogenic progenitor depletion

Aims: Fibroadipogenic progenitors (FAPs) are a group of resident muscle stem cells capable of differentiating into fibroblasts and adipocytes, contributing to intramuscular fibrotic and fatty degeneration after injury. However, FAPs are also thought to play a crucial role in musc...
