HepatoPac™ Highlights

In this Newsletter:

Dear Krista,

Hepregen recently expanded HepatoPac™ to include a new model incorporating Kupffer cells. We've also updated our website www.hepregen.com to make it easier to use with more in-depth information about our contract services and our HepatoPac technology. It includes library of scientific resources which we will continue to enhance over time. We would appreciate your thoughts and feedback, so please email us at info@hepregen.com. From all of us on the Hepregen team, we hope you find these updates valuable and we thank you for your continued interest and support.

Featured Application

HepatoPac-Kupffer Cell Inflammation Model

The HepatoPac™ liver model has been supplemented with primary Kupffer cells, resident macrophages in the liver, that produce cytokines which promote inflammatory reactions. This enhanced platform is stable for over 10 days and can be used to study inflammation-mediated toxicities. Learn more.

HepatoPac co-cultures supplemented with Kupffer cells:

  • Enable evaluation of inflammation-based toxicity
  • Model both normal and inflamed physiological liver states
  • Retain viability for more than 10 days in vitro
  • May be used to monitor drug-drug interactions such as therapeutic protein-small molecule interactions

HepatoPac™-Kupffer cell co-cultures were treated with different cytokines (IL-2, IL-1β, IL-6 and TNF-α). IL-6 caused suppression of CYP3A4 activity in both the presence and absence of Kupffer cells. Importantly, a dose-dependent and Kupffer cell-enhanced suppression of CYP3A4 activity was observed upon exposure to IL-1β.
