Heterogeneity of cadherin-8 expression in the neonatal rat striatum: comparison with striatal compartments.
Mechanisms of organization of the striatal compartments are poorly understood, although involvement of cell adhesion molecules in the compartmentalization has been suggested. Cadherin-8 distribution in the neonatal rat striatum was immunohistochemically studied using a rabbit anti-cadherin-8 antiserum. Intensity of cadherin-8 immunolabeling in the striatum was heterogeneous from postnatal day 0 to postnatal day 7. At postnatal day 9, cadherin-8 immunoreactivity was so weak that heterogeneity was no longer clearly seen. Cadherin-8 immunoreactivity was not detectable at postnatal day 14. Cadherin-8-rich and cadherin-8-poor areas were identical to calbindin-rich areas and tyrosine hydroxylase-rich patches, respectively, in allocation, indicating that cadherin-8 was predominantly expressed in the striatal matrix. These results suggest that cadherin-8 is involved in formation of the striatal compartmentalized structures during brain development.
