Growth of Human iPSC-Derived Organoids by Suspension Culture Using Happy Cell ASM

(A) Time-lapse bright-field images of TkDN4-M-derived organoids cultured in Matrigel, Happy Cell ASM, or FCeM, each supplemented with 25% WRN CM and requisite ingredients for human organoid culture. Scale bars, 200 μm.

(B) Whole-mount images of TkDN4-M-derived organoids cultured in Happy Cell culture medium were stained with phalloidin (blue), together with each indicated antibody. Scale bars, 50 μm.

(C and D) Relative mRNA levels of the indicated genes in TkDN4-M-derived organoids cultured in Matrigel (C) or Happy Cell ASM (D) for 5 days and then exposed to each pre-stimulation medium containing the indicated concentrations of recombinant human IL-22 for 2 days. The relative mRNA levels were determined by qPCR and normalized to GAPDH. The assays were performed in three independent biological replicates. Data presented as mean ± SEM.
