| Research Abstract |
In this study, I examined the processes of rhombomere-boundary formation in the Pax6 mutant rat hindbrain. This study suggests that Pax6 may repress neuronal differentiation through Notch signaling pathway in the rhombomere-boundary cells. I also analyzed cell behavior in the hindbrain of EphA4/ephrinB3b double knockdown-zebrafish embryos using high resolution-confocal time-lapse imaging. GFP^+ interface cells at r3/4 boundary abnormally elongated along the A-P axis and then migrated into r4 region, suggesting that EphA4/ephrinB3b signaling is required for sharpening rhombomere boundaries via regulation of cell migration and cell polarity.
