ABSTRACT
OBJECTIVE:
To observe the relationship between the mechanism of bone marrow stem cell mobilization mediated the myocardial fibrosis inhibition in rats and the non-classical pathway mediated by transforming growth factor-ß (TGF-ß).METHODS:
Twenty two Wistar rats were subcutaneously injected with isoproterenol (Iso) to establish the model of myocardial fibrosis, and then were randomly divided into control group and granulocyte colony-stimulating factor (G-CSF)-treat group (GT group). The rats in GT group were subcutaneously injected with recombinant human granulocyte stimulating factor for 5 days, and the control group was injected with normal saline. After 4 weeks, the myocardial structure was observed by pathological staining, the content of serum B type natriuretic peptide (BNP) was detected by ELISA , the expression of type â ¢ collagen was detected by immunohistochemistry staining and the protein expression level of typeâ collagen, TGF-ß, transforming growth factor kinase 1 (TAK1), mitogen-activated protein kinase kinase (MKK) and p38 mitogen-activated protein kinase (p38MAPK) was determined by Western blot.RESULTS:
Compared with the control group, the serum BNP level, Masson staining collagen deposition, collagen area ratio and the expression of typeâ collagen, TGF- ß, TAK1, MKK3 and p38MAPK in the GT group were lower than those in the control group.CONCLUSION:
Bone marrow stem cell mobilization can alleviate the degree of myocardial fibrosis in rats, which is related to the inhibition of TGF- ß/TAK1/MKK/p38MAPK pathway.Palabras clave
