Abstract
Soft nanofibrous oligopeptide hydrogels consisting of self-assembled l- and d-form Fmoc-Phe-Phe-Cys networks photo-cross-linked by poly(ethylene glycol)-dimethacrylate, which are referred to as l- and d-gel, respectively, were developed for investigation of chirality effects on the undifferentiated state of mesenchymal stem cells. Encapsulated mesenchymal stem cells in d-gel showed slower growth and less spreading, resulting in higher maintenance of the undifferentiated state, compared to in l-gel. This indicates that d-form peptide materials might be useful as scaffold materials for regenerative medicine using stem cells.
