Nonapical Symmetric Divisions Underlie Horizontal Cell Layer Formation in the Developing Retina In Vivo
Symmetric cell divisions have been proposed to rapidly increase neuronal number late in neurogenesis, but how critical this mode of division is to establishing a specific neuronal layer is unknown. Using in vivo time-lapse imaging methods, we discovered that in the laminated zebrafish retina, the horizontal cell (HC) layer forms quickly during embryonic development upon division of a precursor ...
متن کاملEmbryonic divisions
The British prime minister, Gordon Brown, may have been hoping for a quiet Easter break but he soon got warning in the press of an issue that would scupper any such thoughts. The government is backing a bill that will put into law many of the practices currently licensed case by case by the Human Fertilization and Embryology Authority. Britain is currently one of the nations at the forefront of...
متن کاملNumber of Nuclear Divisions
The cell number of the early Drosophila embryo is determined by exactly 13 rounds of synchronous nuclear divisions, allowing cellularization and formation of the embryonic epithelium [1]. The pause in G2 in cycle 14 is controlled by multiple pathways, such as activation of DNA repair checkpoint, progression through S phase, and inhibitory phosphorylation of Cdk1, involving the genes grapes, mei...
متن کاملWidespread impact of horizontal gene transfer on plant colonization of land
In complex multicellular eukaryotes such as animals and plants, horizontal gene transfer is commonly considered rare with very limited evolutionary significance. Here we show that horizontal gene transfer is a dynamic process occurring frequently in the early evolution of land plants. Our genome analyses of the moss Physcomitrella patens identified 57 families of nuclear genes that were acquire...
متن کاملPerfect divisions of a cake
The problem studied in this paper arises from a simple practical problem: how to divide a cake among the children attending a birthday p a r t y i n s u c h a way that each c hild gets the same amount o f c a k e and (perhaps more important to them) the same amount of icing. Let S be a convex set contained in the (xx y)-plane. In mathematical terms, a c a k e C with base S is a solid containing...
