Abstract

The present study aimed to explore the potential of combined treatment with mesenchymal stem cells (MSCs) and danshen for angiogenesis and bone regeneration in a rabbit model of avascular necrosis of femoral head (ANFH). A rabbit model of ANFH was established using the Shwartzman reaction with methylprednisolone and Escherichia coli endotoxin injection. Magnetic resonance imaging (MRI) and histopathological examination were used to evaluate the rabbit model of ANFH. The rabbits were randomly divided into the danshen group, the MSCs group, the danshen combined with MSCs group and the model group (treated with physiological saline). The expression level of monocyte chemoattractant protein‑1 (MCP‑1) and stromal cell‑derived factor‑1 (SDF‑1) were determined by reverse transcription polymerase chain reaction (RT‑PCR). The expression level of bone morphogenetic protein‑2 (BMP‑2) and vascular endothelial growth factor (VEGF) were detected by immunofluorescence and the mRNA expression of BMP‑2 and VEGF were detected by RT‑PCR. Typical osteonecrosis occurred in the rabbit model of ANFH, which indicated that the model was successfully established. MCP‑1 and SDF‑1 were significantly increased in the model group compared with the normal group (P<0.05). Following the administration of MSCs and Salvia miltiorrhiza (danshen), MSCs labeled with 5‑bromo‑2‑deoxyuridine were observed to be gathered in the necrotic area. The increased migration of MSCs to the necrotic area may be due to the upregulated expression of the chemokines MCP‑1 and SDF‑1. ANFH treated with danshen combined with MSCs may promote revascularization by increasing the expression of VEGF and BMP‑2 in the femoral head, promoting re‑ossification and revascularization. Danshen combined with the transplantation of MSCs may be regarded as a novel therapy for the treatment of ANFH in a clinical setting.
