Immortal hepatic stellate cell lines: useful tools to study hepatic stellate cell biology and function?
At the cellular level, the activation and transdifferentiation of quiescent hepatic stellate cells (HSC) into myofibroblasts is the key process involved in hepatic fibrogenesis that is associated with an increased and altered deposition of extracellular matrix components in the liver. The temporal sequence of molecular events associated with stellate cell activation turned out to be appropriate...
متن کاملPharmacological Intervention in Hepatic Stellate Cell Activation and Hepatic Fibrosis
The activation and transdifferentiation of hepatic stellate cells (HSCs) into contractile, matrix-producing myofibroblasts (MFBs) are central events in hepatic fibrogenesis. These processes are driven by autocrine- and paracrine-acting soluble factors (i.e., cytokines and chemokines). Proof-of-concept studies of the last decades have shown that both the deactivation and removal of hepatic MFBs ...
متن کاملIsolation and characterization of six human hepatic isometallothioneins.
Human hepatic metallothionein (MT) was separated into six isoforms by using reversed-phase h.p.l.c. at the analytical and preparative levels. By comparison with the h.p.l.c. elution profiles of the charge-separable species MT-1 and MT-2 isolated by the procedure of Bühler & Kägi [(1974) FEBS Lett. 39, 229-234], five of these isoproteins are identified as hitherto unresolved subforms of MT-1, an...
متن کاملEstablishment and Characterization of an Immortalized Human Hepatic Stellate Cell Line for Applications in Co-Culturing with Immortalized Human Hepatocytes
BACKGROUND AND OBJECTIVE The liver-specific functions of hepatocytes are improved by co-culturing hepatocytes with primary hepatic stellate cells (HSC). However, primary HSC have a short lifespan in vitro, which is considered a major limitation for their use in various applications. This study aimed to establish immortalized human HSC using the simian virus 40 large T antigen (SV40LT) for appli...
متن کاملAnaphylatoxin C5a modulates hepatic stellate cell migration
BACKGROUND C5a and its cognate receptor, C5a receptor (C5aR), key elements of complement, are critical modulators of liver immunity and fibrosis. However, the molecular mechanism for the cross talk between complement and liver fibrosis is not well understood. C5a is a potent chemokine regulating migration of cells in the innate immune system. Since activation and migration of hepatic stellate c...
