The correct functioning of the liver is ensured by the setting and the maintenance of hepatocyte polarity. The complex polarity of the hepatocyte is characterized by the existence of several basolateral and apical poles per cell. Many in vitro models are available for studying hepatocyte polarity, but which are the more suitable? To answer this question, we aimed to identify criteria which dete...

The western barred bandicoot, Perameles bougainville, is an endangered Australian marsupial species. Routine histology of liver samples collected at necropsy from 19 of 20 (95%) western barred bandicoots revealed the sporadic to common occurrence of abnormal hepatocyte nuclei characterized by margination of chromatin and concomitant central pallor. Some abnormal hepatocyte nuclei were mildly to...

Estrogens play central roles in sexual development, reproduction, and hepatocyte proliferation. The ovaries are one of the main organs for estradiol (E2) production. Ovariectomies (OVXs) were performed on the female mice, and hepatocyte proliferation was analyzed. The ovariectomized mice exhibited delayed hepatocyte proliferation after partial hepatectomy (PH) and also exhibited delayed and red...

Met is a tyrosine kinase that has hepatocyte growth factor as its ligand. Met plays a major role in cell growth, migration and morphological changes. Overexpression of hepatocyte growth factor and Met and mutations and amplification of MET have been noted in many forms of cancer and are reportedly correlated with cancer progression and a poor prognosis. Over the past few years, these molecules ...

Introduction: Severe industrial diseases result from the hepatic accumulation of mercury, cadmium or chromium in humans and on the other hand cadmium and dichromate and mercuric salts may induce lung or kidney cancer. Acute or chronic CdCl2, HgCl2 or dichromate administration induces hepatic and nephrotoxicity in rodents. Oxidative stress is often cited as a possible cause of metal induced cell...

The human umbilical vein, as a readily available stem cell source, is a good alternative to harvest mesenchymal stem cells. Human umbilical cord vein mesenchymal stem cells have recently been isolated and have demonstrated the ability to differentiate into various cell types such as fat, bone, cartilage and neuronal cells. In this study, we have investigated whether human umbilical cord vein me...

The development of novel culture systems that mimic the in vivo microenvironment may be beneficial for inducing the differentiation of stem cells and promoting liver function. In the present study, spheroid cultures and decellularized liver scaffolds (DLSs) were utilized to obtain differentiated hepatocyte‑like cells. Mouse bone marrow (BM)‑derived mesenchymal stem cells (MSCs) self‑aggregated ...

Human embryonic stem cells (hESC) provide access to the earliest stages of human development and because of their high proliferation capability, pluripotency and low immunogenicity may serve as a potential source of specialized cells for regenerative medicine. hESC-derived hepatocyte-like cells exhibit characteristic hepatocyte morphology, express hepatocyte markers and are capable of executing...
