Regenerative Therapy Approaches and Encountered Problems in Sensorineural Hearing Loss

Area of Science:

• Bioengineering
• Regenerative Medicine
• Neuroscience

Background:

• Hearing loss is a major global health issue impacting social, psychological, and cognitive well-being.
• Sensorineural hearing loss results from damage to cochlear hair cells and neurons, often caused by genetics, aging, or ototoxic drugs.
• Current treatments like hearing aids and cochlear implants are limited and cannot fully restore natural hearing.

Purpose of the Study:

• To review advancements in stem cell and gene therapy for sensorineural hearing loss.
• To explore bioengineering approaches for regenerating cochlear function.
• To identify challenges in applying these regenerative strategies.

Main Methods:

• Review of stem cell therapies (endogenous and exogenous) for hair cell and neuron regeneration.
• Analysis of gene therapy techniques, including gene silencing, replacement, and CRISPR/CAS9, for treating genetic hearing loss.
• Compilation of bioengineering perspectives on current research and difficulties.

Main Results:

• Stem cell technologies show potential for regenerating damaged cochlear cells and neurons.
• Gene therapy offers promising avenues for addressing genetic causes of hearing loss and promoting hair cell regeneration.
• Significant challenges remain in the clinical application of these regenerative treatments.

Conclusions:

• Stem cell and gene therapy represent promising frontiers for treating sensorineural hearing loss.
• Overcoming bioengineering and clinical hurdles is crucial for successful implementation of regenerative treatments.
• Further research is needed to fully restore cochlear function and address the limitations of current therapies.
