As a result, genetically modified regenerated silk fibroin (GMRSF) hydrogels exhibited better mechanical characteristics compared with RSF hydrogels. Additionally, compared with RSF hydrogels, GMRSF hydrogels exhibited stronger osteogenic differentiation function on rat bone mesenchymal stem cells (BMSCs). In\u00a0vivo, GMRSF hydrogel also showed better osteogenic differentiation function. While the mechanism behind this remains unclear, the outstanding osteogenesis ability of GMRSF sheds light on applications in orthopaedic diseases in the future such as bone defects.\n
