title: Human embryonic organ of Corti in tissue culture and NSE expression.
abstract: For the first time ever, the cochlear tissue of the human embryo has been successfully grown in vitro in two cases, and neuro-specific enolase (NSE) immunoreactivity was studied in one of these tissues. The outer hair cells were arranged in three rows, and the inner hair cells in one row and in better order than the outer hair cells. After NSE immunostaining, the outer spiral bundle, tunnel fiber, outer hair cells, inner hair cells, and the spiral ganglion cells showed positive staining. This data suggests that the human embryonic cochlea has nearly reached complete maturation by 16 weeks, and that the tissue of the Corti organ can be differentiated and matured in vitro.
