B10 – In situ characterization of mediator controlled immune cell interaction in GAG-modified aECM

The project aims on the mechanistic characterization of cellular interactions of macrophages and fibroblasts in three-dimensional fibrillar biomaterials with defined mechanical properties and GAG-modifications in vitro. In particular we investigate the modulation of paracrine cell-cell interactions via relevant mediators (IL-10, TGF-beta, MCP-1) by the GAG modification of the collagen based matrices. Besides quantitative analysis of transport kinetics of mediators in the fibrillar matrices, we characterize proliferation, migration and differentiation on single cell level and in a time-resolved manner of the coculture systems.
