The cadherin-related neuronal receptor (CNR)/protocadherin (Pcdh) a family is one of the diverse protocadherin families identified as a candidate diversified membrane-associated component regulating the formation of neuronal connectivity. However, its expression during neural circuit formation has not been examined in detail. Here, we used a conserved sequence to study the expression of this protein family during-the development of neocortical connectivity, by immunohistochemistry and in situ hybridization. The proteins were detected in developing thalamocortical and corticofugal axons, and in subplate neurons, which pioneer these axon tracts. The expression in subplate neurons was confirmed by birth-date labeling with BrdU, and by examination in homozygous reefer mice. This pattern of CNR/Pcdhalpha expression suggests its involvement in the development of neocortical connectivity
