Ability of the differentiated HLCs to store different metabolites. The resultant hiPSC-EB-HLCs and hiPSC-EB + EC-HLCs showed hepatocyte functional activities, such as (a) Indocyanine green (ICG - Cardiogreen) uptake; (b) ICG release after 6 hours; (c) cytoplasmic accumulation of neutral triglycerides and lipids indicated by Oil-Red O staining; (d) glycogen storage indicated by PAS staining; and (e) Acetylated low-density lipoprotein (DiI-ac-LDL) uptake in red. Both conditions with and without endothelial cells showed a similar ability for all the metabolites assessed. Undifferentiated hiPSCs were used as negative control. Scale bar 100 μm.
