Design of Recombinant Spider Silk Proteins for Cell Type Specific Binding

Abstract: Cytophilic (cell‐adhesive) materials are very important for tissue engineering and regenerative medicine. However, for engineering hierarchically organized tissue structures comprising different cell types, cell‐specific attachment and guidance are decisive. In this context, materials made of recombinant spider silk proteins are promising scaffolds, since they exhibit high biocompatibility, biodegradability, and the underlying proteins can be genetically functionalized. Here, previously established spider silk variants based on the engineered Araneus diadematus fibroin 4 (eADF4 (C16)) are genetically modified with cell adhesive peptide sequences from extracellular matrix proteins, including IKVAV, YIGSR, QHREDGS, and KGD. Interestingly, eADF4 (C16)‐KGD as one of 18 tested variants is cell‐selective for C2C12 mouse myoblasts, one out of 11 tested cell lines. Co‐culturing with B50 rat neuronal cells confirms the cell‐specificity of eADF4 (C16)‐KGD material surfaces for C2C12 mouse myoblast adhesion.
