| 3 | A biomaterial-based therapy for lower limb ischemia using Sr/Si bioactive hydrogel that inhibits skeletal muscle necrosis and enhances angiogenesis显示文摘Muscle necrosis and angiogenesis are two major challenges in the treatment of lower-limb ischemic diseases.In this study,a triple-functional Sr/Si-containing bioceramic/alginate composite hydrogel with simultaneous bioactivity in enhancing angiogenesis,regulating inflammation,and inhibiting muscle necrosis was designed to treat lower-limb ischemic diseases.In particular,sodium alginate,calcium silicate and strontium carbonate were used to prepare injectable hydrogels,which was gelled within 10 min.More importantly,this composite hydrogel sustainedly releases bioactive Sr^(2+)and SiO_(3)^(2-) ions within 28 days.The biological activity of the bioactive ions released from the hydrogels was verified on HUVECs,SMCs,C2C12 and Raw 264.7 cells in vitro,and the therapeutic effect of the hydrogel was confirmed using C57BL/6 mouse model of femoral artery ligation in vivo.The results showed that the composite hydrogel stimulated angiogenesis,developed new collateral capillaries,and re-established the blood supply.In addition,the bioactive hydrogel directly promoted the expression of muscle-regulating factors(MyoG and MyoD)to protect skeletal muscle from necrosis,inhibited M1 polarization,and promoted M2 polarization of macrophages to reduce inflammation,thereby protecting skeletal muscle cells and indirectly promoting vascularization.Our results indicate that these bioceramic/alginate composite bioactive hydrogels are effective biomaterials for treating hindlimb ischemia and suggest that biomaterial-based approaches may have remarkable potential in treating ischemic diseases. | Ye Yuan Zhaowenbin Zhang Fandi Mo Chen Yang Yiren Jiao Enci Wang Yuchong Zhang Peng Lin Chengkai Hu Weiguo Fu Jiang Chang Lixin Wang | 2023 | Bioactive Materials2023，，8： | 0 |
