To investigate whether hair cell immunophenotypes can be derived from the central nervous system.
We established in vitro cell cultures from embryonic day 14.5 fetal rat brain tissue, and analysed changes in the immunohistochemical features of these cell cultures following differentiation.
The immature neural progenitors obtained from the fetal mouse central nervous system generated cell immunophenotypes which expressed epitopes of the hair cell marker proteins myosin VIIa and Brn-3c and the supporting cell marker pan-cytokeratin.
Neural progenitors have the potential to differentiate into inner ear hair cell and supporting cell phenotypes, and thus may be a useful material for cell transplantation therapy aiming to replace damaged inner ear hair cells.
