Initiation of dorso-ventral axis during chick limb development
We analysed spatio-temporal expression of dorso-ventral genes - Wnt-7a, En-1, Lmx-1 and Fgf-8 - during both normal and ectopic limb formation following fibroblast growth factor (FGF) application to the flank. We confirm that Wnt-7a is the first of these genes to be expressed in dorsal ectoderm in limb-forming regions. We also noticed patterns and kinetics of gene expression specific to chick th...
متن کاملNotch and PKC Are Involved in Formation of the Lateral Region of the Dorso-Ventral Axis in Drosophila Embryos
The Notch gene encodes an evolutionarily conserved cell surface receptor that generates regulatory signals based on interactions between neighboring cells. In Drosophila embryos it is normally expressed at a low level due to strong negative regulation. When this negative regulation is abrogated neurogenesis in the ventral region is suppressed, the development of lateral epidermis is severely di...
متن کاملInversion of the dorso-ventral axis in amphibian embryos by unilateral restriction of oxygen supply.
ACCORDING to the hypothesis advanced by L0vtrup (1958) the supply of oxygen is one of the factors responsible for the determination of bilateral symmetry in amphibian embryos. The protein coat covering the outside of the egg is known to have a very low permeability (Holtfreter, 1943), and it was suggested in the hypothesis that the formation of the grey crescent consists in a stretching of this...
متن کاملPositional Cues in the Drosophila Nerve Cord: Semaphorins Pattern the Dorso-Ventral Axis
During the development of neural circuitry, neurons of different kinds establish specific synaptic connections by selecting appropriate targets from large numbers of alternatives. The range of alternative targets is reduced by well organised patterns of growth, termination, and branching that deliver the terminals of appropriate pre- and postsynaptic partners to restricted volumes of the develo...
متن کاملA glimpse into dorso-ventral patterning of the Drosophila eye.
During organogenesis in all multi-cellular organisms, axial patterning is required to transform a single layer organ primordium into a three-dimensional organ. The Drosophila eye model serves as an excellent model to study axial patterning. Dorso-ventral (DV) axis determination is the first lineage restriction event during axial patterning of the Drosophila eye. The early Drosophila eye primord...
