Abstract:

Objective  To investigate the effect of fibroblast growth factor (FGF) on the proliferation and transdifferentiation of cardiac fibroblasts (CFs) into myofibroblasts (MFs).    Methods  Rat CFs were isolated and cultured, and then induced by FGF. CCK-8 was used to detect the cell activity and proliferation. Immunofluorescence and Western blotting were used to detect the expression of α smooth muscle actin (α-SMA) and collagen Ⅰ (ColⅠ).    Results  The expression and activation of α-SMA and ColⅠ increased with the increase of CFs culture generation. The number of CFs induced by FGF did not increased significantly; the expression of α-SMA in CFs induced by FGF1 and FGF2 decreased, and the number of activated MFs decreased.    Conclusion  FGF family has no effect on the proliferation of CFs, but FGF1 and FGF2 can inhibit the activation of CFs and reduce the differentiation into MFs.
