[The effect of serum concentration on the growth, proliferation and collagen secretion in mouse L929 fibroblasts].

To observe the effect of serum concentration on the growth, proliferation and secretion of collagen I, collagen III and hydroxyproline in mouse fibroblasts L929, to optimize serum concentration for cell growth, proliferation and collagen secretion.L929 cells were divided into 6 groups cultured in the present of 0 mL/L, 200 mL/L, 400 mL/L, 600 mL/L, 800 mL/L and 1 000 mL/L serum respectively. Acridine Orange and HE staining were performed on 2 d,...
