ABSTRACT

BACKGROUND:

Bone marrow stromal stem cel s have multilineage differentiation capacity and can differentiate into transparent chondrocytes under certain conditions, which can provide new thoughts for treatment of osteoarthritis.

OBJECTIVE:

To investigate the effects of Tougu Xiaotong Granule containing serum on the cartilage differentiation of bone marrow stromal stem cel s.

METHODS:

Bone marrow stromal stem cel s from Sprague-Dawley rat limbs were cultured in vitro, and those cel s at passage 3 were used in the study. Cel s were divided into six groupssaline serum group, Tougu Xiaotong Granule water extract group, Tougu Xiaotong Granule alcohol extract group, chondroinductive group, Tougu Xiaotong Granule water extract and chondroinductive group, Tougu Xiaotong Granule alcohol extract and chondroinductive group. The Sox9, col agen Ⅱ, and col agen X mRNA and protein expression levels were tested by real-time polymerase chain reaction and western blot analysis. RESULTS AND

CONCLUSION:

After cel s were intervened with drug-containing serum for 14 days, the Sox9, col agen Ⅱ, and col agen X mRNA and protein expression in Tougu Xiaotong Granule water extract group, Tougu Xiaotong Granule alcohol extract group, chondroinductive group, Tougu Xiaotong Granule water extract and chondroinductive group, Tougu Xiaotong Granule alcohol extract and chondroinductive group were significantly higher than that in saline serum group (P<0.05, P<0.01). In addition, the chondroinductive group, Tougu Xiaotong Granule water extract serum and chondroinductive group, Tougu Xiaotong Granule alcohol extract and chondroinductive group showed significantly higher expression levels than Tougu Xiaotong Granule water extract serum group, Tougu Xiaotong Granule alcohol extract group (P<0.01). Sox9 expression in Tougu Xiaotong Granule water extract serum and chondroinductive group were significantly higher than that in the chondroinductive group. Experimental findings indicate that, Tougu Xiaotong Granule containing serum can accelerate bone marrow stromal stem cel s differentiate into cartilage cel s by up-regulation of Sox9 expression.
