cardiovascular system
• at E11.5 the intersomitic vessels are disorganized and extend ectopically throughout the somite

embryo
• at E11.5 ectopic intersomitic vascular growth results in exuberant growth and loss of the normal segmented pattern

The vascular network is disorganized in Sema3etm1Ddg/Sema3etm1Ddg retinas

vision/eye
• at P4, mice exhibit disordered axonal fibers in the retina compared with wild-type mice
• at P4, mice exhibit vascular defects in the retina with clusters of retinal ECs, attachment of hyaloid vessels to the retinal surface, disorganized vascular, decreased vascular density remodeling, and ectopic vascular invasion into the ganglion cell layer compared to in wild-type mice
• at P4, vascular pathfinding in the retina is restricted compared to in wild-type mice
