Fig. 7: Inheritance of Dscam1 mRNA and Dscam1 protein, and lineage depend repulsion.

Schematics of Dscam1 transcription in NEs and newer NBs under the control of Hth behind the proneural wave (a). Graded distribution of Dscam1 mRNA and Dscam1 protein in neurons of the same lineage that controls lineage-dependent repulsion within M0 layer and innervation to different columns (b).
