Directed Differentiation of stem cells to cochlear phenotypes
Dr Bryony Nayagam
We are born with a finite number of cochlear hair cells and neurons and these specialised cell types do not regenerate. In addition, they are susceptible to a number of insults including loud noise, certain anitbiotics, cisplatin and ageing. Hearing loss may also have genetic origins. The aims of this basic research is to generate cochlear sensory cell phenotypes (hair cells and auditory neurons) from human pluripotent and induce pluripotent stem cells. Differentiated cells are charactersied using a combination of molecular, physiological and imaging techniques and are interrogated to better understand basic anatomy and physiology. Projects under this research theme involve multi-disciplinary, cross-institutional collaborations between A/Prof Mirella Dottori, A/Prof Alice Pebay and Dr Rebecca Lim.
