Tenascin-C from the tissue microenvironment promotes muscle stem cell maintenance and function through Annexin A2
Tenascin-C (TnC) produced by the fibro-adipogenic progenitors (FAPs) is required for MuSC maintenance and function. FAP-secreted TnC signals through Annexin-A2 on the MuSC surface to promote self-renewal and regeneration potential.
