Core Tip

Core tip: In recent decades, few studies have focused on the development of hepatocyte serum-free medium. In this study, we developed a novel hepatocyte serum-free medium suitable for in vitro culture of C3A cells and applied an advanced method, gene-chip array, to explore the effect of sericin on the hepatocyte transcriptome. We found that sericin probably enhanced cell attachment through the CCR6-Akt-JNK-NF-κB pathway and promoted cell proliferation through CCR6-mediated activation of the ERK1/2-MAPK pathway. These findings inspired the following study on the mechanism by which sericin promotes cell attachment and proliferation.
