【 摘 要 】

References(19)Cited-By(3)Hepatic stellate cells (HSCs) intracellularly preserve vitamin A in the normal liver. When the liver is damaged, HSCs transform into myofibroblast-like cells, and then proliferate and increase their expression of collagen. Cultured on a plastic plate, HSCs spontaneously activate. To maintain HSCs in a quiescent state with low expression of collagen, coating methods with extracellular matrixes (ECMs) such as Matrigel-coating or laminin-rich coating are commonly used for HSC cultivation. Kishimoto et al. [14] reported that Fragmin®/protamine microparticles (F/P-MPs) have the ability to absorb heparin-binding cytokines like ECMs. Therefore, we examined whether the cultivation on an F/P-MPs-coated plate maintains the quiescent state of RI-T cells (derived from rat HSCs) including the suppression of collagen expression. We found that the mRNA levels of collagen type IαI and TGF-β1 in RI-T cells were significantly suppressed in the cultivation on F/P-MPs-coated plates compared to cultures on noncoated and Matrigel-coated plates. We conclude that the F/P-MPs coating method is useful for maintaining with low expressions of collagen IαI and TGF-β 1 mRNA levels in HSCs.
