Cyprio’s solution, HepatoPearl, is a liver 3D cellular model that is easy to handle, adaptable to any bioassay and any established experimental pipeline. HepatoPearl can provide precise answers to drug assays such as long term DMPK, DILI and drug efficacy.[/custom_font]

HepatoPearls are produced using cryopreserved and freshly isolated PHH. They have been characterized and validated by our research team using different donor cells.
Key Features of HepatoPearls include:[/custom_font]

Homogenous oxygen and nutrient diffusion supports cell physiology within the HepatoPearls over long periods.[/custom_font]

Cell polarization, tight junctions and bile canaliculi network presence are some of the major aspects present in HepatoPearls, which impacts their physiological relevance as an in vitro model. Presence of tight junction protein, ZO-1 as well as cytoskeleton protein, F-actin, in the HepatoPearls indicates the analogy of this in vitro model to the native tissue.[/custom_font]
[custom_font font_size=”19″ line_height=”26″ font_style=”normal” text_align=”left” font_weight=”300″ text_decoration=”none” text_shadow=”no” margin=””]HepatoPearls are viable during 6 weeks and maintain their morphological structure and physiological characteristics all along this period. Besides, transparency of alginate allows real-time microscopic screening of cell behavior in HepatoPearls.[/custom_font]

[custom_font font_size=”19″ line_height=”35″ font_style=”normal” text_align=”left” font_weight=”300″ text_decoration=”none” text_shadow=”no” margin=”100px 0 0″]HepatoPearls maintain a high metabolic level over 5 weeks: major Cytochrome P450 enzymes, phase II metabolizing enzymes and nuclear receptors.
Moreover, long-term CYP P450 cytochromes inducibility of HepatoPearls is validated with three reference inducer molecules (omeprazole, phenobarbital, and rifampicin) and their three target enzymes (CYP1A2, CYP2B6, and CYP3A4).[/custom_font]
