Distinct regulatory states control the elongation of individual ... The sea urchin larval skeletogenesis provides an excellent platform to tackle this question. In the early stages of sea urchin skeletogenesis, skeletogenic genes are uniformly expressed in the skeletogenic lineage. Yet, during skeletal elongation, skeletogenic genes are expressed in distinct spatial sub-domains. Embryology and Development of the Musculoskeletal System First, it is a relatively slow process. The divisions occur approximately 12 to 24 hours apart. Second, there is a unique orientation of the cells with relation to one another. The first cleavage is a meridional division, but, in the second division, one pair of cells divides meridionally and the other divides equatorially ( Fig. 1.1 ).

Use of Echinoderm Embryos to Study the Basic Mechanisms of ... In recent years, it has been shown that the ECM of the sea urchin embryo is a very complex structure, consisting of a number of layers organising during different developmental steps. Using specific antibodies, different storage compartments of the ECM components, like granules and vesicles, have been identified in the unfertilised egg cytoplasm. Architecture and evolution of the cis-regulatory system of the ... - eLife The embryonic skeleton of euechinoid sea urchins, the best studied taxon, is formed by a specialized population of skeletogenic cells known as primary mesenchyme cells (PMCs).
