Research has not yet fully explained the mechanisms behind efficient hair cell regeneration in birds, but recent discoveries have sparked multiple promising research directions that might bring us closer to developing treatments for humans.
A Cell Type–Specific Approach to Detail the Role of a Small Molecule in Hair Cells
Interestingly, some of the genes that were more active in the variant hair cells are typically more active in the supporting cells than in the hair cells. It could be that when miR-96 is a variant, some genes more specific to supporting cells, and which are typically kept turned off in hair cells, incorrectly become activated in hair cells.
A Boost to Inner Ear Organoid Development
This paper explored the potential of the stem cell-derived inner ear organoid system for studying early mammalian placode development. The results will benefit future inner ear organoid applications, such as high-throughput drug screening and cell therapy.
