Icariin promotes angiogenesis in glucocorticoid‐induced osteonecrosis of femoral heads: In vitro and in vivo studies

The injury and dysfunction of the femoral head microvascular endothelial cells are associated with the pathogenesis of glucocorticoid‐induced osteonecrosis of the femoral head (ONFH). Reports indicate that icariin (ICA) can enhance vascular roles and also inhibit endothelial cell dysfunction. However, it still remains unclear whether ICA can promote angiogenesis in glucocorticoid‐induced ONFH. In this study, we investigate this hypothesis...
