20-P028 A fatemap of placodes in Xenopus laevis

Cell migration has been studied extensively in vitro, however, fewer studies address this subject in vivo. Our aim is to determine in vivo, the role of the actin regulatory protein, Ena. To enable this we are studying Drosophila hemocytes in the developing embryo. Hemocytes are the primary immune cells of Drosophila and during development they follow stereotyped pathways to distribute throughou...

20-P030 The cloning and characterization of MADD-3, a LAMMER kinase required for muscle arm extension in Caenorhabditis elegans

fluorescent dyes Dil or DiO via microinjection to generate a fatemap of the non-neural ectoderm of Xenopus laevis embryos during neurulation. Our lineage analysis confirms that all placodes arise from a common primordium and indicates the regions of origin of the different placodes. We further use time-lapse videomicroscopy to analyse the cell movements and behaviour of ectodermal cells of deve...

Cortical grafting in Xenopus laevis.

T H E amphibian egg bears a cortex as the periphery of its cytoplasm. The interpretation by Dalcq & Pasteels (1937) of experiments performed by Pasteels (1938, 1940, 1941), in which fertile eggs of Rana fusca were centrifuged or inverted, led to the suggestion that the cortex possesses properties which control the course of development to some degree. It appeared that the properties of the cort...
