Schematic showing microwell array PDMS plate based liver-on-a-chip device. (B) Generated 3D spheroids (mono-culture and co-cultured) on day 3 and 8. Reproduced from Lee et al (58) with permission from The Royal Society of Chemistry. (C) Hydrogel-based 3D bioprinted hepatic construct. hiPSC-HPCs and the support cells were patterned using two-step 3D bioprinting technique. (D) Fluorescent image is showing patterns of hiPSC-HPCs (green) and supporting cells (red). (E) Fluorescent images of albumin, E-cadherin, and nucleus staining of hiPSC-HPCs without supporting cells and in 3D triculture constructs. Reproduced from Ma et al.
