Promethera Biosciences’ technology platform is based on a newly discovered cell type, isolated from normal human adult liver tissue: Heterologous Human Adult Liver-derived Progenitor Cells (HHALPC). Promethera Biosciences has developed an innovative technology to isolate and expand the progenitor cell type in order to develop two products: HepaStem and H2Stem.


HepaStem is a therapeutic product designed to treat liver diseases by allogeneic liver injection of HHALPC.
