Fig 8. Comparison of the CC Phenotypes in WT and PlexinA1 KO brains at E17.5.

Fig 8

Npn1+ callosal axons crossed the midline in 18 out of 24 WT mice at E17.5 (arrows in A, B, and C). In contrast, Npn1+ callosal axons crossed the midline only in four out of 25 PlexinA1 KO mice at E17.5 and did not cross the midline in 21 KO mice (arrowheads in D, E, and F). Scale bars: 200 μm.
