概要 BACKGROUND:Hepatocytes are an attractive cell source in hepatic tissue engineering because they are the primary cells of the liver, maintaining liver homeostasis through their intrinsic function. Due to the increasing demand for liver donors, a wide range of methods are being studied to obtain functionally active hepatocytes. iPSCs are one of the alternative cell sources, which shows great promise as a tool for generating hepatocytes.METHODS:This study determined whether factors associated with iPSCs contributed to variation in hepatocyte-like cells derived from iPSCs. The factors of concern for the iPSCs included the culture system, the source of iPSCs, and cell seeding density for initiating the differentiation.RESULTS:Our results found iPSC-dependent variances among differentiated hepatocyte-like cells. The matrix used in culturing iPSCs significantly impacts cell morphologies, characteristics, and the expression of pluripotent genes, such as OCT4 and SOX2, varied in iPSCs derived from different sources. These characteristics, in turn, play a consequential role in determining the functional activity of the iPSC-derived hepatocyte-like cells. In addition, cell seeding density was observed to be an essential factor for the efficient generation of iPSC-derived hepatocyte-like cells, with 2- 4 × 10 cells/cm of seeding density resulting in good morphology and functionality.CONCLUSION:This study provides the baseline of effective differentiation protocols for iPSC-derived hepatocyte-like cells with the appropriate conditions, including cell culture media, iPSC source, and the seeding density of iPSCs.
