Abstract:

BACKGROUND: Inflammation is an important factor in cervical spondylotic vertebral arteriopathy, bone marrow mesenchymal stem cells have the potential to treat cervical spondylotic vertebral arteriopathy because of the immunomodulatory effects to inhibit inflammation. 
OBJECTIVE: To investigate the injury mechanism of vascular injury in the model of cervical spondylotic vertebral arteriopathy and to study the therapeutic effects of bone marrow mesenchymal stem cells on it.
METHODS: Forty Japanese big ear rabbits were randomly divided into four groups: control group, model group, tanshinone group, and stem cell group. After modeling, the control and model groups were not given intervention, while the tanshinone and stem cell groups were injected with tanshinone II A sodium sulfonate solution (10 mL) and bone marrow mesenchymal stem cell suspension (10 mL) along the ear vein, respectively. After 2 weeks, the routine pathological examination was done to observe the vascular morphological changes, immunofluorescence staining was done to observe the cathepsin B expression in the vertebral artery, and ELISA was used to detect the expression of tumor necrosis factor-α and interleukin-6 in the vertebral artery.
RESULTS AND CONCLUSION: Compared with the model group, the arterial smooth muscle cell hypertrophy and hyperplasia was obviously restrained in stem cell group, and vascular endothelial fold was in symmetry, while no significant difference was found between stem cell group and tanshinone group. Compared with the model group, expressions of cathepsin B, interleukin 6 and tumor necrosis factor-α expression were reduced significantly in the stem cell group (P < 0.05), while there was no difference between the model and tanshinone groups (P > 0.05). Inflammatory reaction may be one of mechanisms for vertebral artery damage, and bone marrow mesenchymal stem cells can effectively inhibit inflammation of the vertebral artery and improve vascular remodeling.
