nervous system
• mice exhibit abnormal formation of the descending hindbrain axonal tract and severe defasciculation of the spinal cord dorsal funiculus compared with wild-type mice
• mice exhibit abnormal formation of the descending hindbrain axonal tract and severe defasciculation of the spinal cord dorsal funiculus compared with wild-type mice
• endfoot detachment
• at E11.5, commissural axons exhibit robust postcrossing trajectory defects with failure to project to the lateral portion of the funiculus and altered lateral and ventral funiculi ratio compared with wild-type mice
• at E13, a large number of commissural axons project abnormally within the floor plate unlike in wild-type mice
• at E13.5, mice exhibit extensive disruptions in more lateral aspect of the ventrolateral funiculus compared with wild-type mice
• mice exhibit abnormal formation of the descending hindbrain axonal tract and severe defasciculation of the spinal cord dorsal funiculus compared with wild-type mice

• mice exhibit abnormal formation of the descending hindbrain axonal tract and severe defasciculation of the spinal cord dorsal funiculus compared with wild-type mice
• mice exhibit abnormal formation of the descending hindbrain axonal tract and severe defasciculation of the spinal cord dorsal funiculus compared with wild-type mice
• endfoot detachment
• at E11.5, mice exhibit progressive fragmentation of the basement membrane surrounding the spinal cord which is accompanied by detachment of radial neuroepithelial endfeet from the basal surface unlike wild-type mice
