B05 | Glycoengineering as a tool to control the behavior of mesenchymal stem cells in biofabrication processes
The modification of the microenvironment of cells by using glycosyltransferases / glycosidases and synthetic sugar structures represents a new tool for the development of bioinks as well as for the transient modification of cell surfaces. Bioinks will be functionalized by glycoengineering in such a way that cells selectively adhere and differentiate. On the other hand, the extracellular glycocalyx will be modified and / or a protective polysaccharide layer will be added to protect cells from shear forces arising during bioprinting. The long-term goal is to modify cells and bioinks by glycoengineering in such a way that the post-production behavior of cells is optimized in biofabricated constructs.
