Abstract：
The present work focuses on the development of biomaterials that support the adhesion and the proliferation of adipose-tissue derived stem cells. Therefore, gelatin and starch are selected as starting materials. Both hydrogel building blocks are of great interest as they provide a general chemical structure comparable to the protein and the polysaccharide constituting part of the extracellular matrix. Crosslinkable side groups are incorporated on both biopolymers to enable the subsequent chemical crosslinking, thereby ensuring their stability at physiological temperature. An in vitro cellular assay revealed that the hydrogels developed are biocompatible and supported cell adhesion of adipose-tissue derived mesenchymal stem cells. The presence of the starch phase tempered the adhesion resulting in local cell detachment. The results thus indicate that by carefully varying the ratio of the two building blocks, hydrogels can be developed possessing a controllable cell adhesion behavior.
