Enhancement of mesenchymal stem cell angiogenic capacity and stemness by a biomimetic hydrogel scaffold

In this study, we examined the capacity of a biomimetic pullulan–collagen hydrogel to create a functional biomaterial-based stem cell niche for the delivery of mesenchymal stem cells (MSCs) into wounds. Murine bone marrow-derived MSCs were seeded into hydrogels and compared to MSCs grown in standard culture conditions. Hydrogels induced MSC secretion of angiogenic cytokines and expression of transcription factors associated with maintenance of...
