Therefore, we believe that digital methods possess same or even better chemical stability and biocompatibility than conventional casting one. Thirdly, although increased autophagic levels are observed in all test groups, so far there is no evidence that the test metals trigger different levels of autophagy as compared to each other. In addition, correlation analysis indicates that Co, W, and Mn appear to be the potential inducements for the apoptotic and autophagic effects of Co-Cr.Exosomes derived from human umbilical cord mesenchymal stem cells (HUCMSCs) were helpful for injury repair, but whether HUCMSCs-derived exosomes could be encapsulated in a novel nanohydrogel to regulate diabetic wound healing was unclear. Here, HUCMSCs-derived exosomes encapsulated in a bioactive scaffold composed of polyvinyl alcohol (PVA)/alginate (Alg) nanohydrogel (exo@H) was applied to wound healing of diabetic rats. Results found that exo@H could facilitate the proliferation, migration and angiogenesis of HUVECs and sped up the process of diabetic wound healing. We confirmed that exo@H contributed to the expression of the molecules related to wound healing, including SMA, SR-B1 and CD31. Besides, we also found that exo@H up-regulated VEGF level via regulating ERK1/2 pathway. These data demonstrated that exo@H significantly accelerated healing of diabetic wounds in rats by promoting angiogenesis.Tumor cell membrane-derived nanostructures targeting homologous tumors are promising biomimetic drugs. Herein, curcumin (Cur) and chlorin e6 (Ce6) were co-loaded into PLGA nanoparticles (NPs), and then the NPs were coated with MCF-7 cell membranes (MCNPs). Cell membrane coating sharply increased the uptake of MCNPs by homologous cells, as compared to that with naked NPs. The NPs co-loaded with Cur and Ce6 (Cur
