Movie 1

Cilia movement of Foxj1^-1/-1 homozygous mutants are of no apparent defects. Real-time movie of Foxj1^-1/-1 neurula embryo reveals normal cilia movement on the epithelial ectodermal cells, neural ectodermal cells and gastrocoel roof plate cells, compared to that in wildtype embryos. A, B or C in the movie showed ciliary motility in epithelial ectoderm, neural ectoderm or gastrocoel roof plate, respectively.
