title: Cooperative effects in vitro on fibroblast and keratinocyte functions related to wound healing by transforming growth factor-beta and a low molecular weight fraction from hemolyzed blood.
abstract: Blood or its constituents, respectively, contain a.o. substances such as TGF-beta (transforming growth factor-beta), PDGF (platelet-derived growth factor) and other factors, which beneficially influence wound healing. Patients with perivascular disturbances and consequently with inadequate supply of the affected tissue cells often suffer from poor healing of dermal wounds. Here, various cellular functions in situations of poor supply and related to wound healing, such as proliferation, colony formation, and migration of fibroblasts, and of monolayer formation by keratinocytes were emulated in vitro by supplementing cultures with reduced amounts of serum. Computer-aided image analysis allowed to quantify the cellular reactions under normal and serum-deprived medium conditions and under the influence of a low molecular weight fraction manufactured by dialysis of hemolyzed calf blood (HD, Solcoseryl) and of TGF-beta. Both preparations are in use for the treatment of poorly healing wounds. While HD preferentially normalized the reduced viability of fibroblasts, the keratinocyte activity was enhanced by TGF-beta. Restoration of fibroblast and keratinocyte functions proved most effective when combining HD with TGF-beta.
