Mechanical stimulation is known to affect cell proliferation, differentiation, and regeneration. Here, the authors demonstrate that stretching mouse skin recruits macrophages and polarizes them into M2 cells that facilitate hair regeneration through the release of growth factors, including HGF and IGF-1
