چکیده
Adult hepatocytes are polarised with their apical and basolateral membranes separated from neighbouring cells by tight junction proteins. Although efficient differentiation of pluripotent stem cells to hepatocytes has been achieved, the formation of proper polarisation in these cells has not been thoroughly investigated. In the present study, human embryonic stem cells (hESCs) and human mesenchymal stem cells (hMSCs) were differentiated to hepatocyte-like cells and the derived hepatocytes were characterised for mature hepatocyte markers. The secretion of hepatic proteins, expression of hepatic genes and the functional hepatic polarisation of stem cell-derived hepatocytes, foetal hepatocytes and the HepG2 hepatic cell line were evaluated and the different lines were compared. The results indicate that hESC-derived hepatocytes are phenotypically more robust and functionally more efficient compared with the hMSC-derived hepatocytes, suggesting their suitability for toxicity studies.

متن کاملExpression of Endoderm and Hepatic Specific Genes after in vitro Differentiation of Human Embryonic Stem Cells
Background: Human embryonic stem cells (hESC), which are derived from the inner cell mass of the blastocysts, have been considered to be pluripotent cells. In this study we examine the differentiating potential of hESC into hepatocytes by characterization of the expression of endoderm and liver-specific genes. Methods: hESC were cultivated in suspension to form aggregates, the embryoid bodies. ...
متن کاملDevelopment of Simple Protocol for Generation of Functionally Active Hepatocyte-like Cells from Human Adipose Tissue-derived Stem Cells
Background and Aims: Human adipose tissue-derived stem cells (hASCs) are considered as an attractive source of regenerative stem cells, mainly because of their higher proliferation rate, more accessibility and hepatocyte like properties as compared to mesenchymal stem cells isolated from other tissues. Numerous studies have described the beneficial use of adipose tissue-derived stem cells for g...
متن کاملWharton’s Jelly-derived Mesenchymal Stem Cells can Differentiate into Hepatocyte-like Cells by HepG2 Cell Line Extract
Background: Wharton’s jelly is an unlimited source of stem cells that can be used in cell therapy and tissue engineering without any ethical concern. It has been revealed the cell-free extract could be effective to induce cell differentiation. The objective of this study was to induce Wharton’s jelly-derived mesenchymal stem cells (MSCs) into hepatocyte-like cells by premeabilization of the cel...
متن کاملComparison of the liver function and hepatic specific genes expression in cultured mesenchymal stem cells and hepatocytes
Objective(s): Stem cell therapy is believed to be as a promising treatment strategy for tissue repair and regeneration. The plasticity specification of the adult stem cells, such as MSCs, has enabled that these cells to be used in the treatment of a broad spectrum of diseases like liver disorders. In this study, the production of urea and Albumin (Alb), glycogen storage, and expression of some ...
