Involvement of bFGF in the lung response to silica in a mouse model / 中国病理生理杂志

ABSTRACT

AIM: To investigate the relationship between basic fibroblast growth factor (bFGF) and the development of silicosis in mice. METHODS: MTT test was utilized to examine the effects of bFGF-neutralizing antibody and the bronchoalveolar lavage fluid (BALF) of the mice exposed to silica on lung fibroblast cell growth. RESULTS: BALF from mice treated intrabronchially with silica promoted the growth of lung fibroblasts and anti-bFGF antibody inhibited the effect of BALF dramatically. CONCLUSION: These results indicates that bFGF secretion increases in lung in a mice silicosis model and participates in the development of silicosis.
