<p>(A) Schematic view of transgenes containing parts of NOCE. (B) 1 hr β-galactosidase staining of different promoter-reporter transgenes in chimeric embryos. (C) Over night β-galactosidase staining of chimeric embryos carrying the transgenes depicted under (A). The stage is indicated at the top and the transgene at the left site. Arrow heads point at stained notochords.</p
