Goldfish β-catenin cell-autonomously inhibits the expression of early neural development regulating gene vsx1

β-catenin gene is essential for the formation of normal dorsal axial structure in vertebrates. Recent studies have provided evidence that β-catenin has a certain role in restricting the amount of organizer-induced neurectoderm formation in zebrafish and Xenopus laevis. To further understand how β-catenin represses the induction of neurectoderm formation and whether the inhibition of neural progenitor fates is essential for the normal organizer formation, it was investigated whether β-catenin was involved in...
