CD301b+ Macrophages Are Essential for Effective Skin Wound Healing.

ABSTRACT: Regeneration of skin's barrier function after injury requires temporally coordinated cellular interactions between multiple cell types. Macrophages are essential inflammatory cells in skin wound regeneration. These cells switch their phenotype from inflammatory in the early regenerative stages to anti-inflammatory in the midstages of healing to coordinate skin repair. However, little is known about how different subsets of anti-inflammatory macrophages contribute to skin wound healing. Here, we characterize midstage macrophages (CD45(+)/CD11b(+)/F4-80(+)) and identify two major populations: CD206(+)/CD301b(+) and CD206(+)/CD301b(-). The numbers of CD206(+)/CD301b(+) macrophages increased concomitantly with repair, when the anti-inflammatory phenotype switch occurs in midstage healing. Usin
