Fig. 1. Key gene expression and migration patterns in telencephalic development.
(A) The key morphogens, (B) the patterning transcription factors and (C) the
main pathways of ventrodorsal cell migration in a frontal section of a
DAPI-labelled telencephalon of the developing mouse telencephalon at embryonic
day 13. Many signalling and migrational pathways, as well as transcription
factors, have been omitted, as we have illustrated here just the morphogens,
transcription factors and migrational pathways discussed in the text. Dark
green, late migrating interneurons; light green, early migrating interneurons;
red, late generated oligodendrocytes; yellow, early generated
oligodendrocytes. c. hem, cortical hem; ctx, cerebral cortex adjacent to the
choroid plexus (yellow); lge, lateral ganglionic eminence; mge, medial
ganglionic eminence.
