Abstract: The development of auditory organoids represents a groundbreaking advancement in auditory research and regenerative medicine. These three-dimensional tissue structures, derived from pluripotent stem cells, replicate the architecture and function of the human inner ear, including the key sensory and neural cell types such as hair cells, supporting cells, and neurons. Auditory organoids enable researchers to study inner ear development, model genetic hearing disorders, and evaluate the effects of ototoxic drugs. Recent breakthroughs include the successful differentiation and functional validation of hair cell-like structures responsive to sound signals, as well as the integration of LGR5+ hair cell progenitor cells to enhance regenerative capacity. Despite significant progress, there remain many challenges of achieving full functional maturation, improving reproducibility, and scaling production for clinical applications. This emerging technology holds immense potential for understanding the inner ear biology, advancing personalized medicine, and developing novel therapies for hearing loss and balance disorders.
