scRNA-seq of mouse cochlea organoid cells

GER cells proliferate to form organoids and give rise to nascent hair cells and supporting cells. To investigate the growth-promoting pathways in GER cells, we generated organoids from highly enriched mouse GER cells and performed single-cell RNA sequencing.

Data analysis revealed changes in gene expression in GER-derived cells during the early growth phase of organoid development. Integrating single-cell RNA sequencing data with in vitro and in vivo functional assays, we identified galectins and Myc activity as essential regulators of GER cell proliferation.
