ReproHepato™: The world’s first commercial hiPSC-hepatocytes
Product Classification : hiPSC-HepatocytesResearch Theme : Drug Effect Test, Pharmacological Effectiveness Test, Drug metabolism, Hepatitis, Safety Test, Toxicology test
Constantly available human hepatocytes with robust enzymatic activity
- Robust CYP activity
- Expression of transporters (NTCP and OATP1B1, etc.)
- Longer retention of CYP activity
- Hepatotoxic response similar to primary hepatocytes
- CYP induction assay and hepatotoxicity assay services available in Japan
ReproCELL has launched ReproHepato™ – constantly available, high-quality, and fully-differentiated human hepatocytes derived from iPS cells that are commercialized for the first time in the world..
The cells provided are differentiated hepatocytes. After six days in culture using Maintenance Medium included in the kit, the cells are ready for CYP assay.*: The cells should be kept in liquid nitrogen.
High-purity CYP-positive hepatocytes from human iPS cells
ReproHepato™ cells have typical human hepatocyte-like morphology and characteristics.The expression of key hepatic
components such as CYP3A4, HNF4a, E-cadherin, and albumin in high percentages of ReproHepato™ cells is indicative of the high purity of these cells.

Robust CYP activity and induction capability (Assay service available in Japan)
CYP3A4 activity is modulated by typical inducers and inhibitors in a dose-dependent manner, as in the case of primary hepatocytes.
Activity and inducibility of other CYPs (1A2/2C9/2C19) is also observed at levels comparable to those of primary hepatocytes.
CYP2D6 activity is also observed in the upcoming version of ReproHepato, which is under development now.
ReproCELL offers a contract CYP assay service using in Japan ReproHepato. Please contact ReproCELL for the details of CYP assay service.
Small lot-to-lot variation; more consistent results
Compared to primary hepatocytes, ReproHepato? hepatocytes show less lot-to-lot variation in CYP activity and inducibility.

Long life in culture
ReproHepato can be cultured for a long time in vitro while retaining hepatic functions. Contact ReproCELL for the preliminary results.
