The Role of Pax6 in Lens Placode Formation
THE ROLE OF PAX6 IN LENS PLACODE FORMATION by Jie Huang Washington University in St. Louis, 2010 Professor David Beeebe, Chairperson Although placodes are ubiquitous precursors of tissue invagination, the mechanism of placode formation and its importance for invagination are unclear. We tested the …

GENETIC CONTROL OF EYE AND CENTRAL NERVOUS SYSTEM DEVELOPMENT
… not replace Pax6 for its auto-regulation in lens induction or for neural differentiation in retina. In brain development, however, we demonstrated that cell proliferation in the cerebral cortex and dorsoventral patterning of the telencephalon and neural tube was partially rescued in either …

Role of Xenopus Pitx3 during early development.
… Rathke's pouch. xPitx3 is expressed throughout lens induction in the presumptive lens ectoderm, lens placode, and later in differentiating lens. During tailbud stages, xPitx3 is also expressed symmetrically in the pituitary, lateral plate mesoderm, branchial arches, somites, and asymmetrically …

New insights into cornea-lens regeneration in Xenopus laevis: the role of Wnt/beta-catenin signaling and the regenerative capacity of the limbal region
… the cell and molecular mechanisms of lens regeneration in the frog, Xenopus laevis, which possesses a high capacity to regenerate larval tissues, such as the complete regeneration of the lens from the cornea epithelium. To fill in a large void in our current knowledge of the cell …
