Abstract: Disclosed herein are synthetic hydrogel useful for the generation, storage and administration of cellular structures such as spheroids and organoids.

Abstract: The generation of complex organ tissues from human embryonic and pluripotent stem cells (PSCs) remains a major challenge for translational studies. It is shown that PSCs can be directed to differentiate into intestinal tissue in vitro by modulating the combinatorial activities of several signaling pathways in a step-wise fashion, effectively recapitulating in vivo fetal intestinal development. The resulting intestinal “organoids” were three-dimensional structures consisting of a polarized, columnar epithelium surrounded by mesenchyme that included a smooth muscle-like layer. The epithelium was patterned into crypt-like SOX9-positive proliferative zones and villus-like structures with all of the major functional cell types of the intestine. The culture system is used to demonstrate that expression of NEUROG3, a pro-endocrine transcription factor mutated in enteric anendocrinosis is sufficient to promote differentiation towards the enteroendocrine cell lineage.
