This study investigated the effect of basic fibroblast growth factor (bFGF) on collagen synthesis in cultured HCFs and explored its possible mechanism of action. The results showed that bFGF significantly promoted collagen synthesis in HCFs, and its effects were concentration-dependent; also activated PI3K/Akt and ERK/MAPK signaling pathways to promote collagen synthesis. These results provide a theoretical basis for further studying the effect of bFGF on the occurrence and development of heart diseases.【Keywords】Basic fibroblast growth factor; Human cardiac fibroblasts; Collagen synthesis; PI3K/Akt signaling pathway; ERK/MAPK signaling pathway
