HIOs are a promising cell source for intestinal tissue repair, disease modeling, and drug screening. Previous work has demonstrated that HIOs engraft to the injured intestinal wall in vivo, however, these approaches are significantly limited by the lack of an appropriate delivery vehicle to drive HIO engraftment. HIO generation from hPSCs is a multi-stage directed differentiation process comprising three stages: (I) a definitive endoderm 2D monolayer, (II) self-organized 3D aggregates (human intestinal spheroids, HIS), and (III) intestinal specification into HIOs within a 3D extracellular matrix. This in vitro culture process spans a 2D growth substrate (stage I and II) to a 3D matrix (stage III). The growth stages (2D and 3D) are supported by Matrigel, a murine tumor-derived basement membrane extract with ill-defined composition, lot-to-lot variability, and limited clinical translation potential presenting a major roadblock to HIOs clinical translation. Another roadblock to HIO technologies is the low yield and consistency of HIS differentiation in HIOs.
