A10 – Glycosaminoglycan-poly (ethylene glycol) -hydrogel to improve dermal wound healing

The proposed project aims at the characterization and application of biohybrid hydrogels based on glycosaminoglycans (GAG, chondroitin sulfate, dermatan sulfate, heparin) or GAG derivatives (hyaluronan sulfates, selectively desulfated heparin) and star-shaped end-functionalized poly (ethylene glycol) , Which are to be prepared by various in situ crosslinking reactions and incorporating functional (eg MMP-cleavable) peptides with graded physicochemical properties. The GAG ??component of the materials is determined by the covalent attachment of adhesion ligand peptides and by loading with GAG-binding cytokines (eg FGF-2, VEGF, PDGF, TGF-IL-4, IL-10, IL -13, etc.), wherein the sulfation patterns of the glycosaminoglycan and the degradation rate of the gels are adapted to control the rate of release. This material platform is to be used in the development of previous work on angiogenesis-stimulating starPEG-heparin-hydrogels in order to stimulate the recruitment of endothelial cells by specifically orchestrated exogenous signals Precursor cells and the morphogenesis of endothelial cells into capillary networks and to influence the activation and differentiation of macrophages and fibroblasts. The project is therefore closely co-operating with B3, B4 (macrophage activation, angiogenesis, migration and differentiation of dermal fibroblasts), B2 and B5 (growth factors and cytokines of bone regeneration) and A4 (SDF-1 derivatives for local enrichment of endothelial precursor cells ). Further collaborations within the Transregio are planned with A6 (diffusion of growth factors in GAG-based hydrogels), Z4 (analysis of cell secreted ECM in heparin-based hydrogels) and B10 (tracking methods for the analysis of cellular infiltration of GAG-based hydrogels) Hydrogels). With all subprojects of the A-Division, further detailed adjustments to preparative concepts and analytical questions are planned in the characterization of GAG-based polymer matrices.
