MES islands located near a surface epithelium removed by cell migration. Confocal live imaging of GFP expression in E15.5 Crect^Tg/0; R26^mTmG/+ secondary palate sagittal section shows an epithelial island coalescing into the nearby oral surface. Images were captured every 15 minutes for 20 hours. Scale bar, 20μm.

A unique form of collective epithelial migration is crucial for tissue fusion in the secondary palate and can overcome loss of epithelial apoptosis
