IMPROVED METHOD FOR GENERATING INNER EAR ORGANOIDS

Espacenet Family 93562606

Abstract

The invention relates to a method of generating endolymph-producing epithelial cells and in vitro use of a hedgehog signalling inhibitor for differentiation of inner ear progenitor cells into endolymph-producing epithelial cells; in vitro endolymph-producing epithelial cells and an inner ear organoid comprising endolymph-producing epithelial cells. Also provided is in vitro use of an inner ear organoid in drug discovery; the endolymph-roducing epithelial cells for use in a method of treating diseases of the inner ear; and a method of testing one of more therapeutic agents using these cells or organoids. Lastly, also provided is a kit and an organoid maturation medium.
