Sequential survival laparotomies to successively combine components of tissue-engineered small intestine: (a) Schematic illustration of the “double-surgery” procedure, followed by IVIS bioluminescence imaging and explanation. (b) Injection of ICG-tagged ENCCs into HIO-TESI during second survival operation. (c) Flow cytometry of ENCCs for CD271 (P75NTR) and CD57 (HNK1) at day 15. Isotype control antibodies were applied. HIO: human intestinal organoid; ENCC: enteric neural crest cell; ICG: indocyanine green dye; HIO-TESI: tissue-engineered small intestine derived from human intestinal organoids; IVIS: in vivo imaging system.
