描述 Cryopreserved HepaRG™ Cells 长描述 Cryopreserved, terminally differentiated hepatic cells derived from a human liver progenitor cell line that retains many characteristics of primary hepatocytes 背景信息 Hepatocytes are an important and fundamental tool for the study of both a drugs’ metabolism and it’s toxicity. Traditionally hepatocytes have been sourced from from livers not accepted for transplant or from the resected margin of liver carcinoma patients. However, this supply of fresh hepatocytes is unpredictable, the material is often of poor quality, subject to genetic and environmental variability and increasingly costly.
Currently customers are forced to utilize less than ideal tissue sources, including recombinant enzymes expressed in non-mammalian cells, rat hepatocytes, human enzymes and transporters expressed in non-hepatocyte recombinant cell lines, and cryopreserved human hepatocytes. All of these solutions lose some or most of the functional activities of hepatocytes freshly isolated from a healthy human donor.
HepaRG™ cells are terminally differentiated hepatocyte cells that reproducibly express the activities of transporters and drug metabolizing enzymes and facilitate studies of uptake, metabolism, and disposition of drug candidates.
They respond and function like primary human hepatocytes across a range of applications.
They do not require daily medium changes, are reproducible and can be stored until required
Can be used across different types of studies at a lower overall cost than human primary hepatocytes产品信息 部件 - Pack contains 1vials of mycoplasma-free cells, 1 ml per vial (>8 x 106 cells)

应用说明 The similarity of HepaRG™ to human hepatocytes is well described in journal papers:
“HepaRG activities comparable to those usually found in primary human hepatocyte cultures.” (1)
“hepatocytic markers and liver specific proteins such as albumin are expressed at levels similar to those found in normal liver. Iron storage and metabolism typical of human hepatocytes are intact with HepaRG cells.” (2)
“The (data) generated from the HepaRG cells (were) in excellent agreement with those generated in human hepatocytes” (3)
“The high percentage of translationally controlled probe sets (in HepaRG) is in agreement with the … hepatocyte” (2)
“… the extensive inter-individual variation … renders it difficult to compare data with human hepatocytes … these drawbacks appear to be … overcome with HepaRG cells.” (1)
Metabolic activity of HepaRG™ is comparable to that of human hepatocytes and is reproducible and maintained for multiple weeks:
“ For (CYP3A4) HepaRG activities ranged between 600 and 800 pmol/min/mg during the four-week period, comparable with those usually found in primary human hepatocyte cultures” (1)
“Activities of CYP3A4 and CYP1A2 were found to be relatively stable over the four-week period” (4)
“Our results clearly show that 1099 genes were affected in common in 6 independent experiments using HepaRG in two different laboratories” (1)
HepaRG™ have demonstrated utility for in-vitro assessment of CYP inhibition:
“CYP activities in HepaRG cells are inhibited by diagnostic inhibitors to the same extent as in primary hepatocytes” (5)
HepaRG™ are useful for in-vitro determinations of acute toxicity, mitochondrial damage, metabolite-dependent toxicity, genotoxicity and chronic toxicity risk:
“Our data confirmed that (HepaRG) are metabolically competent and activate different classes of promutagens into reactive metabolites.” (6)
HepaRG™ demonstrate uptake and efflux transporter expression and responses that closely resemble those of human hepatocytes:
“HepaRG were found to display a pattern of transporter expression close to that found in primary human hepatocytes.” (7)
“The fact that HepaRG cells exhibit functional activity of both sinusoidal and canalicular drug transporters is important.” (7)
HepRG™ respond to prototypical inducers including those that activate CAR such as CITCO, which is dependent solely on the CAR pathway, in a fashion similar to the responses of primary human hepatocytes, but HepaRG™can be used for much longer periods than PHH:
“Across nine inducers, the R2 of fold induction of HepRG compared to the mean induction with three lots of primary hepatocytes was 0.94” (8)
