Monolayers of hepatocytes from mouse, hamster, rat, and guinea pig metabolized 2-acetylaminofluorene (AAF) to ether-extractable, water-soluble as well as covalently macromolecular bound products. Hamster hepatocytes showed the highest rate of formation of ether-extractable metabolites, rat and guinea pig the lowest. These species differences reflected mainly differences in the formation of 2-am...

Under a copper-deficient regimen, pancreatic cells in the adult rat can be found to undergo differentiation into hepatocytes. Pancreatic hepatocytes induced in male and female rats were examined for the expression of the androgen-inducible hepatic protein, alpha 2u-globulin. Alpha 2u-Globulin protein was demonstrable by immunoperoxidase method in all the pancreatic hepatocytes of male rats. Nor...

To generate functional human hepatocytes from stem cells and/or extra-hepatic tissues could provide an important source of cells for treating liver diseases. Spermatogonial stem cells (SSCs) have an unlimited plasticity since they can dedifferentiate and transdifferentiate to other cell lineages. However, generation of mature and functional hepatocytes from human SSCs has not yet been achieved....

Candidatus Liberibacter asiaticus (CLas) is a phloem-limited, gram-negative, fastidious bacterium that is associated with the development of citrus greening disease, also known as Huanglongbing (HLB). CLas is transmitted by the Asian citrus psyllid (ACP) Diaphorina citri, in a circulative manner. Two major barriers to transmission within the insect are the midgut and the salivary glands. We per...

The liver is a unique organ that is endowed with a plethora of specialized functions. Most of its functional traits are controlled by hepatocytes. Primary hepatocytes have been used widely in in vitro models to understand the biological processes occurring in the liver. There are a number of methods used to separate hepatocytes, but the cell activity and purity are much lower in this condition....

The number of approved peptide therapeutics has increased significantly in recent years. Peptide have many advances over small molecule drugs, such as higher affinity to target and lower toxicity profiles. Although peptide-like drugs are mainly metabolized/catabolized the body for smaller peptides amino acids, metabolite identification still an essential part their development, especially if st...

The Solt-Farber protocol, in the absence of an initiating agent, was used to examine the precursor-product relationship between oval cells and hepatocytes in rat liver. The animals were administered 2-acetylaminofluorene (AAF) by gavage for 2 wk combined with partial hepatectomy 1 wk after administering AAF Two dose levels of AAF were used: 9- and 21-mg total dose for animals in Groups I and II...

The current application for many potential cell-based treatments for liver failure is limited by the low availability of mature functional hepatocytes. Although adult hepatocytes have a remarkable ability to proliferate in vivo, attempts to proliferate adult hepatocytes in vitro have been less successful. In this study, we investigated the effect of coculture cell type on the proliferative resp...

Chronic hepatitis B (HBV) infection is a major cause of human suffering, and number mathematical models have examined the within-host dynamics disease. Most previous assumed that infected hepatocytes do not proliferate; however, effect HBV on hepatocyte proliferation controversial, with conflicting data showing both induction inhibition proliferation. With family ordinary differential equation ...
