When Cryopreserved Human Hepatocytes (CryoHeps) attach to culture dishes, they are useful to evaluate short-term and long-term repeat-toxicity as well as enzyme-induction potential of drug candidates (details).


KaLy-Cell checks lots of Cryopreserved Human Hepatocytes to ascertain their ability to attach to collagen substratum. Each lot that meets this performance criteria is thereafter characterized for basal Drug Metabolizing Enzyme (DME) activities.  This allows the study of DME-dependent donor-donor variability assessment in metabolism and toxicity of drug candidate (details).

Other characterizations of Cryopreserved Human Plateable Hepatocytes

Specific lots are further characterized for:

  • concentration-dependent response to prototypical inducers. These are useful to evaluate enzyme-induction potential of drug candidates, (Alexandre et al., 2012).

  • long-term culture in a sandwich configuration. These are useful for long-term repeat-exposure toxicity and metabolism studies (Parmentier et al., 2017).    

  • Suitable for drug-Induced-Cholestasis-Index determination (Chatterjee te al., 2014 and Oorts et al., 2016).

  • B-Clear transporter-qualified (details).

Storage and handling of Cryopreserved Human Plateable Hepatocytes

Cryopreserved Human Plateable Hepatocytes should be stored in liquid nitrogen or at -150°C.



biohazardKaLy-Cell has the ability by the French Ministry of Research (AC-2014-2155) to prepare and store products from human origin for research purposes (CSP articles L 1243-3 and L 1243-4), and the ability by the French Ministry of Research to export human samples (CSP article L 1245-5). KaLy-Cell also has the agreement of the French Agency of Biomedicine (CSP article L 1232-3). KaLy-Cell only accepts tissue from donors who test negative for HIV 1 and 2, HTLV, and Hepatitis B and C. However, as a precaution, all human-derived samples should be regarded as a potential biohazard and should be stored, handled and discarded accordingly. Cellular and subcellular fractions are intended for in vitro use only
