“One of the challenges in tackling this condition is that the regenerative ability of the human cochlea is severely limited”, said lead author Dr. Sharon Oleskevich from the Hearing Research Group at The University of New South Wales. “It has been proposed that the transplantation of cells from other parts of the body could treat, prevent or even reverse hearing loss. The transplanted cells have the potential to repair tissue by replacing damaged cells and enhancing the survival of existing cells, preventing the condition from developing further.”
To investigate the effects of this treatment, nasal stem cells were injected into the cochlea of mice displaying symptoms of hearing loss. Mice were chosen for this treatment as they display a similar decline in hearing function following infancy.
