<p>Rapid wound healing is important to regain the skins protective function after injury. Studies have shown that enamel matrix proteins (EMP) have many desirable effects which may accelerate wound healing [Bosshardt <em>et al.</em> 2008].</p><p> </p><p>Polymers (Polymer A, B and C) were formed into a mat form, with or without incorporated enamel matrix derivative (EMD) (Collaboration partner). The materials may be suitable for wound care and drug delivery systems.</p><p> </p><p>Protein release tests were performed on samples incubated in physiological-like solution using pyrogallol red staining, ultraviolet (UV) spectrophotometer and high-performance liquid chromatography (HPLC). Protein was detected in Polymer A material samples, compared to a reference material sample, using pyrogallol red staining. An in vitro experiment showed that normal human dermal fibroblasts (NHDF) cultivated with Polymer A material (with EMD) had significantly higher viability than NHDF cultivated with reference material (Polymer A without EMD) and comparable viability to fibroblasts grown with either 0.1 mg EMD in solution or with 10% fetal calf serum. Images taken of Polymer A material, with incorporated Fluorescein isothiocyanate- (FITC) labeled EMD, indicate a homogenous distribution of EMD peptides and/or EMD aggregates throughout the material. A dressing which contains an active substance may have clinical promise for wound care applications.</p>
