Wound healing is a dynamic process highly dependent on the coordinated functions of inflammatory cells, endothelial cells, fibroblasts, and keratinocytes, with the ultimate goal of restoring skin integrity [1]. This process is a complex integration of cascades, which requires multiple cytokines and growth factors for different stimulatory and inhibitory functions to initiate and direct different phases. Factors involved in wound healing include platelet-derived growth factor (PDGF), transforming growth factor (TGF) and vascular endothelial growth factors (VEGF). Recombinant growth factors advent was followed by their premature and empiric introduction into clinical practice for wound healing treatment, in order to reproduce the physiological process. However, few of them are available for clinical use and they have practical limitations due to their short half-life and excessive cost. The limited success and heterogeneous clinical results obtained by the use of single growth factors are probably related to the requirements for multiple signals to achieve a complete regeneration process, assuming that no single exogenous agent can effectively mediate all aspects needed for tissue repair [2]. Thus, delivery of a wide range of biological mediators is probably required for efficient and complete healing, recreating and propagating the normal sequence of events.
