Abstract (original English)

Background Although multipotential stromal cells/mesenchymal stem cell (MSCs) initially gained attention because of their ability to differentiate into multiple cell lineages, it is their capacity to produce and secrete growth factors and cytokines that makes them particularly valuable as potential cell therapeutics. The problem Wound healing is an intricate process consisting of several integrated stages, including angiogenesis, collagen production, and cell migration and proliferation. Coordinating these processes to ensure rapid and thorough wound healing is necessary when developing therapeutics. This coordination, however, is disrupted in chronic nonhealing wounds, wherein the impaired blood supply and resulting ischemia compromise cellular functions and make it difficult to deliver the necessary signaling molecules. Basic/clinical science advances MSCs secrete a combination of growth factors and cytokines, which have been shown to promote wound repair. This combination of growth factors and cytokines successfully induces angiogenesis, reduces inflammation, and promotes fibroblast migration and collagen production. Clinical care relevance The growth factors and cytokines secreted by MSCs can be administered to wounds by either transplanting cells or, as a safer alternative, using the conditioned medium of MSCs, which contains these secreted bioactive molecules.
