bioGenous™ Human Hepatocyte Organoid Expansion Kit is a chemically defined, serum-free medium formulated for the rapid and high-efficiency proliferation of adult liver-derived hepatocyte organoids. This system enables robust, long-term expansion while faithfully preserving the core physiological characteristics of primary hepatocytes, including the sustained expression of canonical markers such as Albumin and HNF4α. By providing a stable and reproducible environment, the kit facilitates the generation of large-scale organoid cultures suitable for high-throughput drug screening, disease modeling, and regenerative medicine research. As a reliable in vitro platform, it serves as an essential foundation for investigating liver development and hepatobiliary pathophysiology within a precisely controlled, serum-free workflow.
