Most larvae can be grouped into one of five categories based on physical appearance: Body cylindrical with short thoracic legs and 2-10 pairs of fleshy abdominal prolegs. Vertebrate kidney tubules elongate using a planar cell polaritydependent, rosette-based mechanism of convergent extension. The embryo undergoes folding, resulting in transformation of the flat, embryonic disc into an embryo that approaches the human form during the course of the pregnancy.During the folding processes, the abdominal cavity, the abdominal wall, and the gut tube are formed.At the cranial and caudal embryonic poles, there is .

Cell motility driving mediolateral intercalation in explants of Xenopus laevis. The word originates from the Greek word morph which means shape, and genesis meaning creation. Engineering pattern formation and morphogenesis - PMC 19, 213214 (2008). Morphogenesis is a mechanical process involving forces that generate mechanical stress, strain, and movement of cells,[1] and can be induced by genetic programs according to the spatial patterning of cells within tissues.

Development is a systematic process. 238, 14801491 (2009). Diverse regulation of mammary epithelial growth and branching - PNAS Tissue separation can also occur via more dramatic cellular differentiation events during which epithelial cells become mesenchymal (see Epithelialmesenchymal transition). Refs 104 and 105 elegantly demonstrate that changes in substrate mechanics can influence lineage decisions in cultured stem cells. Integrins bind extracellularly to fibronectin, laminin, or other ECM components, and intracellularly to microfilament-binding proteins -actinin and talin to link the cytoskeleton with the outside. Following epithelial-mesenchymal transition, cells can migrate away from an epithelium and then associate with other similar cells in a new location. ADS Nieto, M. A.

Commenting on these recent developments in an article emblematically entitled Digital Morphogenesis, British architect and theorist Neil Leach noted that "architecture [] is no longer so preoccupied with style and appearance.It is as though a new paradigm has emerged [] the more contemporary architects operating within the new morphogenetic paradigm can be seen more as the controllers . The transcriptional regulators YAP and TAZ are shown to act as sensors and mediators of mechanical inputs, therefore providing a mechanism by which force can control gene expression and fate. Virology. Each comprises the fundamental components of development that have commonly been used to categorize the problems that motivate developmental biology. Cell movement, locomotion, and growth activate morphogenesis in animals. 177, 893903 (2007). Morphogenesis | The Embryo Project Encyclopedia The problem of morphogenesis is recognized by many to be one of the most elusive questions of development as it is intertwined with questions of This process of shaping an organism and the development of various organ systems according to the genetically active blueprint of the particular organism based on environmental factors is known as morphogenesis. .

Due to differential affinities, cells are restricted to separate layers during embryonic development. In some insect species the number of instars is constant (typically from 3 to 15), but in others it may vary in response to temperature, food availability, or other environmental factors.

Article Nature Cell Biol. Science 338, 201203 (2012).

Bonner, like Morphogens are soluble molecules that can diffuse and carry signals that control cell differentiation via concentration gradients. 31, 49784993 (2011). PubMed In biology, the process of shaping an organism through organ multiplication and cell differentiation is known as morphogenesis. If it survives, it will periodically outgrow and replace its exoskeleton (a process known as molting). The molting process begins when epidermal cells respond to hormonal changes by increasing their rate of protein synthesis. Biol.
