... alleles uniquely permit non-invasive labeling of cells defined by the overlap of up to three distinct gene expression domains. In response to different combinations of Cre, Flp and Dre recombinases, they express eGFP and/or tdTomato to allow the visualization of full cellular morphology. Here, we...

... between the roles of Hh signalling in zebrafish and amniote inner ear patterning. In wild-type otic vesicles, the three cristae (anterior, lateral and posterior) develop ventrolaterally, as revealed by msxc expression ( Fig. 2A ) and by staining with FITC-phalloidin ( Fig. 2D ). Cristae in dre...

...Elizabeth B. Goodwin; Karen Hofstra; Carol A. Hurney; Susan Mango; Judith Kimble ABSTRACT In Caenorhabditis elegans , the tra-2 sex-determining gene is regulated at the translational level by two 28 nt direct repeat elements (DREs) located in its 3′ untranslated region (3′UTR). DRF is a factor...
