[0087] Wnt and retinoic acid signaling control anterior versus posterior foregut fate

[0088] To generate foregut derivatives, hPSCs were first induced into DE as previously described (Fig. 1), followed by three-dimensional (3D) SOX2-expressing foregut spheroids (D'Amour et al., 2005; Dye et al., 2016); M...

Abstract

The instant disclosure relates to methods for converting mammalian definitive endoderm (DE) cells into specific tissue(s) or organ(s) through directed differentiation. In particular, the disclosure relates to formation of esophageal tissue and / or organoids formed from differentiated definitive endoderm.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to and benefit of US Provisional Application 62 / 570,182 to James Wells, filed October 10, 2017, the contents of which are incorporated in their entirety for all purposes. [0003] Statement Regarding Federally Funded Research [0004] This invention was made with US Government support under NIH Grant No. P01HD093363. The US Government has certain rights in this invention. Background technique [0005] The esophagus actively facilitates the passage of food from the mouth and pharynx to the stomach. It consists of stratified squamous epithelium, a muscular layer, and the enteric nervous system that senses stretch and controls peristalsis. Congenital disorders such as esophageal atresia are caused by genetic mutations that result in narrowing or discontinuity of the lumen. Other diseases affect the esophagus later in life, such as esophageal cancer, eosinophilic esophagitis, achalasia...
