ABSTRACT
ObjectiveTo evaluate the effect of Bone mesenchymal stem cells(BMSCs) intraarticular injection on the pathological development of collagen-induced arthritis(CIA) rats.MethodsCIA Wistar rats were divided into 2 groupsthe saline injection control group and the BMSCs injection group.BMSCs were isolated from normal rats and cultured in vitro till P2 generation,which were injected into the affected the ankle joint consequently.After 2,4,8,12 weeks of processing,the following indexes were observedarthritis score and X-ray.Twelve weeks later,all of the rats were sacrificed and the following histological indexes were evaluatedcartilage destruction and cartilage extracellular matrix secretion.Paired samples t-test was used for the statistical comparison.ResultsAll the arthritis indexes of the BMSCs group were much lower.than those of the saline control group.The arthritis scores were 3.18±0.62 vs 3.84±0.35 (at week 2),3.45±0.28 vs 5.96±0.48(at week 4),3.86±0.23 vs 6.75±0.36(at week 8),4.23±0.43 vs 7.86±0.66 (at week 12) respectively.X-ray scores were 2.04±0.21 vs 2.72±0.15(at week 2),2.52±0.47 vs 4.06±0.38 (atweek 4),3.56±0.29 vs 4.35±0.36 (at week 8),3.73±0.43 vs 4.86±0.62(at weekl2) respectively and the histological evaluation indexes were 2.34±0.22 vs 3.52±0.55 (at week 12).ConclusionBMSCs injection may inhibit the pathological development of CIA rats,and it may be a promising approach for the treatment of rheumatoid arthritis.
