AbstractIn metazoans, skeletal muscle evolved to contract and produce force. However, recent experimental evidence suggests that skeletal muscle has also acquired endocrine functions and produces a vast array of myokines. Using ChIP-Seq and gene expression analyses of myogenic factors, we show that Myf6/MRF4 transcriptionally regulates a broad spectrum of myokines and muscle-secreted proteins, including ligands for downstream activation of key signaling pathways such as EGFR, STAT3 and VEGFR. Homozygous deletion of Myf6 causes a significant reduction in the ability of muscle to produce key myokines such as EGF, VEGFA and LIF. Consequently, although Myf6 knockout mice are born with a normal muscle stem cell compartment, they undergo progressive reduction in their stem cell pool during postnatal life. Mechanistically, muscle stem cells from the Myf6 knockout animals show defects in activation of EGFR and STAT3 signaling, upregulate the p38 MAP kinase pathway and spontaneously break from quiescence. Exogenous application of recombinant EGF and LIF rescue the defects in the muscle stem cell pool of Myf6 knockout animals. Finally, skeletal muscles of mice lacking Myf6 have a significantly reduced ability to sustain donor-engrafted muscle stem cells. Taken together, our data uncovers a novel role for Myf6 in regulating the expression of niche factors and myokines to maintain the skeletal muscle stem cell pool in adult mice.

The skeletal muscle stem cell niche transiently stiffens during the tissue repair process, which serves to increase planar-oriented divisions and, when combined with WNT7a, induces symmetric cell division to expand the stem cell pool.
