The Drosophila E-cadherin homolog, DE-cadherin, is expressed postembryonically by brain neuroblasts and their lineages of neurons ("secondary lineages"). DE-cadherin appears in neuroblasts as soon as they can be identified by their increase in size and then remains expressed uninterruptedly throughout larval life. DE-cadherin remains transiently expressed in the cell bodies and axons of neurons produced by neuroblast proliferation.

The Drosophila N-CAM homolog Fasciclin II (FasII) is expressed during the embryonic period in a subset of central neurons that pioneer the neuropile of the larval brain. Toward the end of embryogenesis, FasII expression in axon tracts diminishes but resumes from the late first larval instar in an increasingly complex pattern of axon tracts that join the tracts laid down in the embryo. We present evidence that FasII is expressed in a major fraction of the long axon tracts that interconnect different domains of the larval brain.
