Kif20b is expressed in cortical apical and basal progenitors. (A,B) Kif20b mRNA is detected in the neuroepithelial progenitor layers of control brains. ctx, cortex; lv, lateral ventricle; mb, midbrain. (C,D) Kif20b mRNA is expressed most strongly in the apical vz of the cortex. (E) Kif20b protein co-localizes with AurB in midbodies of normal apical progenitors but is undetectable in mutants. (F) Kif20b protein is detected in midbodies of presumed basal progenitors in the svz. n=6 of 6 midbodies. Scale bars: 1 mm in A,B; 250 μm in C,D; 7.5 μm in E; 5 μm in F.
