Stabilized generation of human iPSC-derived liver organoids using a modified coating approach.

ABSTRACT: Human-induced pluripotent stem cell (hiPSC)-derived hepatic cells are useful tools for regenerative medicine, and various culture substrates are currently used for their differentiation. We differentiated hiPSC-derived hepatic endoderm (HE), endothelial cells (ECs), and mesenchymal cells (MCs) using Laminin-511 (LN) coating to generate liver organoids, hiPSC-liver buds (hiPSC-LBs), which exhibited therapeutic effects when transplanted into disease model animals. Stably producing significant amounts of hiPSC-LBs is necessary for sufficient therapeutic effects. However, general precoating (standard coating) requires quick manipulation, often causing failure for inexperienced cell cultures, we thus tested direct LN addition to the culture medium (Direct coating).
