Leucine-rich repeats and immunoglobulin-like domains 3 (Lrig3) was identified by microarray analysis among genes that show differential expression during gastrulation in Xenopus laevis.?Lrig3?was expressed in the neural plate and neural crest (NC) at neurula stages, and in NC derivatives and other dorsal structures during tailbud stages. A prominent consequence of the morpholino-induced inhibition of?Lrig3?expression was impaired NC formation, as revealed by the suppression of marker genes, including Slug, Sox9 and Foxd3.
