DiI labeling of the cortex. (A and
B) E14.5 DiI labeling of cortical cells. (Bar = 1
mm.) The white arrow labels the apical dendrite, and the yellow
arrowhead marks the projecting axon. Lis1+/+
(A); Lis1/sLis1, white arrow marks
a neuron that has “normal” morphology, and white arrowheads mark
clusters of neurons that look abnormal (B).
(C and D) E15.5 DiI labeling of cortical
cells. (Bar = 25 μm.) Radial glia fibers are marked with
arrowheads. Lis1+/+ (E),
Lis1/sLis1 (F). V, ventricle; IZ,
intermediate zone; CP*, abnormal CP.
