Tissue morphogenesis arises from coordinated changes in cell shape driven by actomyosin contractions. Patterns of gene expression regionalize cell behaviours by controlling actomyosin contractility.

The compound eye of Drosophila is made up of 800 omma- tidia arranged in a hexagonal array and develops from the larval eye imaginal disc. The reiterated pattern of omma- tidia is established within the morphogenetic furrow (MF) of the eye disc with the differentiation of neuronal photore- ceptor cells (Ready et al., 1976). The MF is a dorsal-ven-

Jul 27, 2006  · The Drosophila retinal determination gene network (RDGN) consists of seven transcription factors, conserved from flies to humans, that cooperate to regulate cell specification and determination during eye development.

Cell-type specification in the Drosophila compound eye begins at the morphogenetic furrow. The furrow sweeps across the developing eye epithelium and is coincident with four classes of cellular events: coordinated changes in cell shape, changes in gene expression, synchronization of the cell cycle, and the specification of a regular array of ommatidial founder cells.

Yet that also means that a select group of biotech stocks have looked this dramatic sell-off right in the eye and come out greener on the. inhibitors specifically designed to block the bone.

To elucidate the roles of CS for craniofacial development, we analyzed the craniofacial morphology. Some of T1KO mice exhibited severe facial developmental defect, such as eye defects and cleft lip.

Later in development, after cells have committed themselves to an eye fate, the morphogenetic furrow sweeps across the retinal epithelium and transforms the eye field into a crystalline-like lattice of evenly arranged unit eyes.

Dec 01, 2008  · Our results provide additional insights into the regulation of atonal expression within the morphogenetic furrow, further illustrating the complex developmental regulation this proneural gene undergoes during eye development. Further, as each of the genes we identified in our screen in Drosophila have mammalian homologs, our results may also.

Metamorphosis of Drosophila involves proliferation, differentiation and death of larval tissues in order to form the adult fly. The major steroid hormone implicated in the larval-pupal transition and adult tissue modelling is ecdysone. Previous reviews have draw together studies connecting ecdysone signaling to the processes of apoptosis and differentiation.

Development of eye tissue is initiated by a conserved set of transcription factors termed retinal determination network (RDN). In the fruit fly Drosophila melanogaster, the zinc-finger transcription factor Glass acts directly downstream of the RDN to control identity of photoreceptor as well as non-photoreceptor cells.

The Drosophila eye emerges during late larval and pupal stage, from a monolayer epithelium called the eye‐antenna imaginal disc. The morphogenetic furrow is a wave of differentiation sweeping across the eye imaginal disc from posterior to anterior initiating sequential differentiation at.

June 7, 2016 – Adding to previous evidence, a study based on a statewide cancer database shows no increase in cancer risk in patients undergoing spinal fusion surgery with the bone-promoting growth.

Maintenance of tissue integrity during development and homeostasis requires the precise coordination of several cell-based processes, including cell death. In animals, the majority of such cell death.

The Drosophila retina is a crystalline array of 800 ommatidia whose organization and assembly suggest polarization of the retinal epithelium along anteroposterior and dorsoventral axes. The retina develops by a stepwise process following the posterior-to-anterior.

Morphogenetic furrow initiation and progression during eye development in Drosophila: the roles of decapentaplegic, hedgehog and eyes absent. Curtiss J , Mlodzik M Developmental Biology Programme, EMBL, Meyerhofstrasse 1, Germany.

The secreted morphogen Dpp plays important roles in spatial regulation of gene expression and cell cycle progression in the developing Drosophila eye. Dpp signaling is required for timely cell cycle arrest ahead of the morphogenetic furrow as a prelude to differentiation, and is also important for eye disc growth.

Transforming growth factor-beta (TGF-β)/bone morphogenetic protein (BMP. The signaling network in skeletal development and bone formation is overwhelmingly complex and highly time and space.

During Drosophila eye development, cell differentiation is preceded by the formation of a morphogenetic furrow, which progresses across the epithelium from posterior to anterior. Cells within the morphogenetic furrow are apically constricted and shortened along their apical–basal axis.

We propose that the morphogenetic furrow coincides with a transient boundary that coordinates growth and differentiation of the eye disc, and that hedgehog is necessary and sufficient to propagate.
