The Role of Myeloid Lineage Cells on Skin Healing and Skin Regeneration

Abstract

Yusef Yousuf and Saeid Amini-Nik

Skin healing a complex and well-orchestrated process that involves the coordination and activity of many cell types. Myeloid lineage cells are inflammatory cells recruited to the wound site that remove injured tissue and invading pathogens. Besides this role, due to their ability to secrete a variety of growth factors and cytokines, myeloid cells influence each stage of wound healing (primarily inflammation and proliferation phases). Abnormalities in myeloid cell function lead to pathologies such as excessive and deficient healing. Therapies based on modulating myeloid cells may hold therapeutic potential. However, further research is needed to fully elucidate the spatial and temporal mechanisms of myeloid cells in skin healing. The objective of this review is to discuss recent findings on the role of myeloid lineage cells in skin healing and regeneration.
