Exploring the application of stem cell technology in treating sensorineural hearing loss.

Sensorineural deafness mainly occurs due to damage to hair cells, and advances in stem cell technology, especially the application of induced pluripotent stem cells (iPSCs) and adult stem cells, provides new possibilities for hair cell regeneration. This review describes the basic knowledge of stem cells and their important applications in regenerative medicine, as well as recent progress in stem cell research in the field of hair cell regeneration, especially the induced differentiation of hair-like cells. At the same time, we also point out the challenges facing current research, including differentiation efficiency, cell stability issues, and treatment safety and long-term efficacy considerations. Finally, we look forward to the direction of future research, and emphasize the importance of the cell differentiation mechanism, simulation of the inner ear microenvironment, safety assessment, and personalized treatment strategies. In conclusion, despite many challenges, stem cell technology has shown great potential in the field of hearing research and is expected to bring revolutionary treatment options for patients with sensorineural hearing loss in the future.
