Newly Identified Pathway links Fetal Brain Development to Adult Social Behavior and embryonic Rx

Representative images of control (left) and Dvl mutants (right) embryonic brains at embryonic day 18.5 (E18.5, just before birth at E20) were stained with DAPI to highlight all of the nuclei (Blue), anti-Ctip2 (Green) for deep layer neurons and anti-Cux1 (Red) for more superficial layer neurons. Analysis of the results shows specific reduction of the deep layer (Ctip2+) neurons at E18.5. This reduction in deep layer neurons is preceded by a transient brain over growth at E14.5, associated with increased proliferation of neural progenitors and premature differentiation.

Autism has been postulated to be caused by neuron overgrowth in the prenatal period, although the precise timing and cause of this overgrowth has been unknown...
