| Research Abstract |
To understand mechanisms underlying neural circuit formation, we analyzed Olig2 function on the diencephalon formation including thalamocortical projection formation. Olig2 deficient mouse shows malformation (reduced size) of the prethalamus and expansion of the thalamic eminence. In addition, thalamocortical axons follow tortuous courses. The prethalamus has long been regarded as an intermediate target for the thalamocortical projection formation. Our results indicate that Olig2 regulates prethalamus formation, and also thalamocortical projection formation with an indirect manner. These results have been submitted to Development, an international journal for developmental biology, and now under revision.
