title: Pre- and postnatal expression of glycoconjugates (3-fucosyl-N-acetyllactosamine and HNK-1 epitopes) in the mouse inner ear.
abstract: The distribution of two glycoconjugates 3-fucosyl-N-acetyllactosamine (CD15) and HNK-1 epitope (CD57) in the inner ear of the NMRI mouse was analysed from the eighth day of gestation to the 16th day after birth. CD15 epitope distribution is developmentally regulated. The up- and down-regulation of expression, the change in the number of cells which are positive, the ingrowth of CD15-positive cells and their distribution, intracellular and/or cell-surface-associated expression, all assume a characteristic appearance at each developmental stage. Distribution of CD57 documented the nerve outgrowth and formation of the innervation of the vestibular apparatus and cochlear duct. Correlation between CD15 and CD57 expression patterns revealed differences in the interaction of the ingrowing fibres and epithelial tissue between the vestibular organ and the cochlea and differences in the development of the cristae and maculae.
