The entire tissues of the attention, together with the lens, the cornea, the ciliary physique, the neuroretina and the retinal pigment epithelium needs to paintings in concord for the conclusion of transparent imaginative and prescient. The phenotypic emergence of every of those tissues calls for intercellular conversation, that is completed via direct actual touch in addition to via diffusion and reception of the molecular beacons. This quantity presents an summary of the molecular and mobile biology of eye improvement and encompasses subject matters like early gene expression within the floor ectoderm and the optic cup, retinal neurogenesis, signaling molecules and axonal information. It provides new findings at the effect of the lens at the improvement of the visible procedure and the way gene expression within the optic cup controls differentiation of the lens fiber mobilephone whereas confirmed principles in regards to the morphogenesis of the ciliary physique are challenged. it is a useful resource of data for developmental biologists and neurobiologists.

The present work provides in vivo evidence of a new role for Pax6 in lens development, namely that in the neural tissue (fig. 5). Although Pax6 expressed in the overlying surface ectoderm initiates lens induction, later NR expression of Pax6 indirectly plays a vital role for lens fiber differentiation. Further work will be needed to identify different signaling factors, which are likely indispensable for proper lens morphogenesis.

Comparisons with the control nonexperimental animals, however, are meaningful. Even after 2 weeks of © 2004 S. com/dne recovery under normal light conditions, the occluded eyes do not seem to reach the same level of Pax-6 expression (number of molecules per mg tissue) as seen in normal control eyes, suggesting that exposure of the posthatch chick eye to FDM impedes developmental progression that normally culminates in emmetropia. Copyright © 2004 S. Karger AG, Basel Introduction Emmetropia is the functional culmination of a myriad of developmental processes that shape the vertebrate visual system.

In addition, the poorly differentiated cells never took on the morphology of fiber cells; they did not elongate and remained as bifurcated clusters within the cavity (fig. 1l, arrowheads). The Reza/Yasuda Fig. 1. Dominant-negative Pax6B (Pax6- EnR) inhibits endogenous Pax6 activity and its overexpression in OV exhibits eye malformation. a Schematic representation of the wild-type and dominant-negative Pax6B gene. ␤-gal assay was performed to follow the repression of endogenous Pax6 activity by Pax6-EnR in vivo (b–g).
