PDX1-expressing dorsal and ventral foregut endoderm
First Claim
1. A cell culture comprising human cells wherein at least about 26% of said human cells are pancreatic-duodenal homoebox factor-1 (PDX1) positive, dorsally-biased, foregut endoderm cells that express at least one marker selected from the group consisting of CDH6, GABRA2, GRIA3, IL6R, KCNJ2, LGALS3, LGALS3/GALIG, SERPINF2, SLC27A2, SERPINF2, DUSP9, CDH6 and SOX9, said PDX1-positive, dorsally-biased, foregut endoderm cells being multipotent cells that can differentiate into cells of the dorsal pancreatic bud.

Abstract
Disclosed herein are cell cultures comprising dorsal and/or ventral PDX1-positive foregut endoderm cells and methods of producing the same. Also disclosed herein are cell populations comprising substantially purified dorsal and/or ventral PDX1-positive foregut endoderm cells as well as methods for enriching, isolating and purifying dorsal and/or ventral PDX1-positive foregut endoderm cells from other cell types. Methods of identifying differentiation factors capable of promoting the differentiation of dorsal and/or ventral PDX1-positive foregut endoderm cells, are also disclosed.
