Abstract: Disclosed herein are esophageal raft culture compositions that more closely resemble native organ structures. These esophageal raft cultures may also be innervated by combination with enteric neural crest cells. These raft culture compositions are advantageous for purposes such as studying organellar function, development, and organization. Also disclosed herein are methods of producing said esophageal raft culture compositions.

Abstract: Disclosed herein are organoids, or compositions thereof, produced through a process of aggregating gut endoderm monolayer and culturing the resultant gut endoderm aggregate. Examples of these aggregated organoids include but are not limited to aggregated liver organoids, aggregated gastric organoids, aggregated intestinal organoids, and aggregated colonic organoids.

Abstract: Described herein are methods for treating a malabsorptive disorder. The malabsorptive disorder may be, in certain aspects, characterized by malabsorption of macronutrients in the intestine, and may include, for example, a disease selected from one or more of enteric anendocrinosis, short gut syndrome, enteric pathogen infection, malnutrition, genetic causes of malabsorption, Celiac disease, malabsorptive diarrhea, and inflammatory bowel. Such methods may include administration of peptide YY (PYY) to an individual in need thereof. Also described are medicaments for carrying out the disclosed methods.

Abstract: Disclosed are methods of inducing formation of a gastric cells and/or a gastric tissue, such as in the form of a gastric organoid. The formation of gastric cells and/or tissue may be carried out by the activating and/or inhibiting of one or more signaling pathways within a precursor cell. Also disclosed are methods for using the disclosed gastric cells, gastric tissues, and/or gastric organoids derived from precursor cells.
