1. A method for producing pancreatic endocrine cells expressing MAFA comprising:
- (a) obtaining a population of cells comprising pancreatic endoderm and endocrine precursor cells;
(b) differentiating the population of cells comprising pancreatic endoderm and endocrine precursor cells into a pancreatic endocrine cell population in a medium comprising (i) a SHH signaling pathway antagonist, (ii) a BMP inhibitor, (iii) T3, a T3 analogue, T4, a T4 analogue or a mixture thereof, and (iv) an ALK5 inhibitor; and
(c) culturing the pancreatic endocrine cell population in a further medium comprising an aurora kinase inhibitor, an RSK inhibitor, an inhibitor of protein methyltransferase DOT 1L, or a combination thereof.

Abstract
The present invention provides methods, cell cultures and differentiation media to promote differentiation of pluripotent stem cells to pancreatic endocrine cells of a mature phenotype. The resulting pancreatic endocrine cells express single hormonal insulin, PDX1, NKX6.1, and MAFA. In one or more differentiation stages, culturing may be carried out in a culture vessel at the air-liquid interface.

10. A method for producing a pancreatic endocrine cell population expressing MAFA, comprising:
-
(a) obtaining a pancreatic endoderm and endocrine precursor cell population; and (b) culturing the pancreatic endoderm and endocrine precursor cell population in a medium, wherein the medium comprises (i) a SMO inhibitor or a SHH signaling pathway antagonist, (ii) a BMP inhibitor, (iii) T3, an analogue of T3, T4, an analogue of T4 or a mixture thereof, (iv) an ALK5 inhibitor, and (v) an aurora kinase inhibitor, an RSK inhibitor, an inhibitor of protein methyltransferase DOT1L, or a combination thereof, thereby producing the pancreatic endocrine cell population, wherein cells in the pancreatic cell endocrine population express MAFA. - View Dependent Claims (11, 12, 13, 14, 15, 16)
