PPARγ is a lipid activated transcription factor essential for fat cells and linked to lipid processing in macrophages. Varga et al. (2016) now show that PPARγ is transcriptionally active and regulates the growth factor Gdf3 in repair macrophages in regenerating skeletal muscle, forming a paracrine axis connecting macrophages to muscle progenitor fusion.
