A study by Australian researchers has found that patients suffering the problem of hearing, which starts during childhood, could benefit from a transplant of stem cells from their nose. It was revealed trough study that mucosa-derivative stem cells can help in conserving hearing job during the early start of sensor neural hearing loss.
The problem of sensorineural hearing loss is occurred due to loss of neurons in the cochlea, which is the sensory organ of the inner ear and is responsible for hearing. The condition can be occurred due to hereditary cause, frequently come up during infancy and childhood, obstructing cognitive growth and escort to talking and language problems.
To analyze the effects of the treatment, a lab study was conducted over mice, in which nasal stem cells were injected into the cochlea of mice with symptoms of hearing loss. These mice demonstrate an analogous decline in hearing function subsequent to childhood. The stem cells correlated to mesenchymal stem cells have used to diminish the degree of hearing loss.
As the cells did not amalgamate into the cochlea, it is probable that the outcomes from the adult stem cells were due to liberate of aspects to conserve function of the endogenous stem cells. Mesenchymal stem cells are known to offer aspects to maintain various types of cells healthy and functioning, explained Jan Nolta, associate editor of Stem Cells.
While comparing mice, which received the transplanted cells with those not had the treatment, researchers found that the hearing doorsill level in stem cell-transplanted mice was considerably lower. The findings exhibit a momentous effect of nasal stem cell transplantations for sensorineural hearing loss, explained study author Dr Sharon Oleskevich from the Hearing Research Group at The University of New South Wales.
The hearing loss were analyzed with help of the auditory brainstem response assay that resolves the lowest sound levels to which brain reacts, called the hearing thresholds. The stem cells can be taken easily from nasal cavity making this transplantation a latent treatment for other conditions counting cardiac infarction and Parkinson’s disease, added Dr Oleskevich.
