Genealogy, Geometry and Genes: Experimental Embryology of Caenorhabditis Eleganson is to serve as an introduction and as a reference source rather than as a complete summary of present knowledge in the field. As indicated by the title, the review will focus on embryonic cell lineages, pattern formation in the embryo and the analysis of mutants affecting early development.

On the Establishment of Polarity in Polychaete Eggsdorsal quadrant is the stem cell for the mesoderm, and the macromeres together with the other micromeres of the fourth quartet form the entoderm. The invariant cleavage pattern as well as the apparant early determination of the blastomeres led to the assumption that the spiralian egg is a developmen

Experimental Embryology In Leeches: Cellular and Molecular Approachess recognised by Charles Whitman in the 1890’s (Whitman, 1878). On the basis of his observations in the light microscope on the early cleavage of a glossiphoniid leech egg, Whitman first stated the idea that each identified cell in the early embryo is developmentally distinct and that each identified

Patterns of Gene Expression During Ascidian Developmentuseful for examining developmental changes during evolution (Berrill, 1931; 1935). Finally, the eggs of the ascidian . contain colored ooplasms (Conklin, 1905b; Berrill, 1929). The most spectacular of these ooplasms is the yellow crescent or myoplasm, a unique cytoskeletal domain that segregates to
