Cell delivery therapy is a talented and hopeful strategic approach to repair the damaged cardiac tissues after myocardial infarction. The biocompatible injectable hydrogel with bioactive nanomaterials with effective self-healing capability has been highly required for the cell delivery and regeneration therapy. In the present study, we have developed the biopolymeric and biocompatible self-healing silk protein hydrogel matrix with graphene oxide nanoformulations as cell delivery vehicles for the treatment of myocardial infarction regeneration. The materials combinations, structural interactions, thermal stability and morphology of the designed hydrogel were investigated and elaborated. To improve therapeutic potential of the hydrogel matrix, growth factor was loaded and investigated its biological activity such as cell survival and cell proliferations properties by using endothelial progenitor cells. Collected, these developed materials are excellent vesicle for cell therapy in myocardial infarction.
