    Notes: [Auszug] THE neural crest is a most peculiar part of the vertebrate embryo. It originates at an early stage from the region where the neural tube pinches off from the rest of the ectoderm. While the neural tube develops into the central nervous system, the cells of the neural crest break loose from the ...

    Notes: [Auszug] Our bodies have a complicated structure, but the messages that pass between cells to coordinate the construction process are simple and few in kind. A handful of basic types of signal are used repeatedly, in different tissues and organisms, to direct cells along one developmental pathway or another ...

    Notch signalling and the synchronization of the somite segmentation clock (2000)

    Notes: [Auszug] In vertebrates with mutations in the Notch cell–cell communication pathway, segmentation fails: the boundaries demarcating somites, the segments of the embryonic body axis, are absent or irregular. This phenotype has prompted many investigations, but the role of Notch signalling in ...

    Notes: [Auszug] The endodermal epithelium of vertebrates generates many types of enteroendocrine cells, including the insulin- and glucagon-secreting cells of the islets of Langerhans. Two studies disclose that Notch signalling controls which cells differentiate as enteroendocrine cells—a finding with ...

    Stress-induced alignment of actin filaments and the mechanics of cytogel (1993)
    Springer
    Bulletin of mathematical biology 55 (1993), S. 637-654 
    Details
    ISSN: 1522-9602
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Mathematics
    Notes: Abstract Experimental evidence suggests that anisotropic stress induces alignment of intracellular actin filaments. We develop a model for this phenomenon, which includes a parameter reflecting the sensitivity of the microfilament network to changes in the stress field. When applied to a uniform cell sheet at rest, the model predicts that for sufficiently large values of the sensitivity parameter, all the actin filaments will spontaneously align in a single direction. Stress alignment can also be caused by a change in external conditions, and as an example of this we apply our model to the initial response of embryonic epidermis to wounding. Our solutions in this case are able to reflect the actin cable that has been found at the wound edge in recent experiments; the cable consists of microfilaments aligned with stress at the wound boundary of the epithelium. These applications suggest that stress-induced alignment of actin filaments could play a key role in some biological systems. This is the first attempt to include the alignment phenomenon in a mechanical model of cytogel.

    Notes: [Auszug] THE complexity of an embryo is the result of diversification and rearrangement: the tissues become subdivided into parts with different characters, and those parts move and become interwoven to form increasingly intricate assemblies. The body segments of a vertebrate provide a good example. As the ...

    Notes: [Auszug] THE fibroblasts that make up the extra-cellular matrix in the adult body may seem dull, commonplace cells, cast in a suppor-ting role while others play the star parts. But fibroblasts in the embryo appear in a more interesting light. They are the cells that carry much of the information that ...

    Notes: [Auszug] EMBRYOLOGY, like many other areas of biology, is bedevilled by simplistic dichotomies. We need them, yet they trip us up. Our ways of thought, and the structure of human language, perpetually drive us towards descriptions based on discrete categories and simple yes/no questions. We can scarcely ...
