查询词典 deposition

Our results revealed that TGF-β1 at 1 ng/ml induced collagen deposition of HSC-T6 cells (145 ± 5 % of controls), and pre-exposure of cells to curcumin (1.25~10 μM) inhibited the stimulatory effect of TGF-β1 in a concentration-dependent manner. Curcumin (10 μM) significantly reduced the TGF-β1-induced collagen deposition (97 ± 7 % of controls) without cytotoxicity in the MTT assay .
