Vertebrate eye development is a dynamic process that couples morphogenesis, migration of extraocular periocular mesenchyme (POM) cells to the eye, and retinal patterning along the nasotemporal and dorsoventral (DV) axes. Aberrant patterning during ocular development often results in defects...

Sensory systems are complex structures that receive stimuli from the surrounding environment and convert them into interpretable information. In the visual system, light hitting the eye is transmitted to the brain in a way that preserves the spatial conformation of the pictures we see. Retinal...

Development of the vertebrate central nervous system is a complex process that relies on the accurate spatiotemporal distribution of signaling centers during embryogenesis. These signals provide cells with positional information, which is integrated via transcription factors and gene regulatory...

The roles of Pbx and Meis TALE-class homeodomain transcription factors in vertebrate neural patterning
DownloadFall 2010
One of the major goals of developmental biology is to understand how specialized groups of cells arise from an initially unspecified cell population. The vertebrate hindbrain is transiently segmented along its anterior-posterior axis into lineage-restricted compartments called rhombomeres, making...

Zic transcription factors regulate retinoic acid metabolism during zebrafish neural development
DownloadSpring 2012
Retinoic acid (RA) has a crucial role in embryonic nervous system development - controlling anterior-posterior patterning, neural differentiation, and cell proliferation. During zebrafish embryogenesis, levels of RA are tightly regulated by the combinatorial action of synthesis and degradation...
