The aim of subproject A01 is the systematic investigation and optimization of adhesive, microstructural as well as microscopic and macroscopic mechanical properties of biofabricated hierarchical tissue analogues based on alginate dialdehyde (ADA). This also includes optimizing the temporal degradation of the alginate matrix and its replacement by a cell-generated extracellular matrix. Our long-term goal is to achieve tight control over the temporal changes in adhesive, mechanical and structural properties and the associated cell-biological behavior in alginate-based biofabricated tissues.
