Prokaryotic organisms (also called prokaryotes) are mostly unicellular (single-celled) and smaller organisms with a simpler cellular organization. Prokaryotes lack a well-defined nucleus and their genetic material is suspended in the cytoplasm without any membrane separation. The genetic material (circular...
Life science aims at a better understanding of multiple biological functions, such as healthy organ development with cellular proliferation, migration and organization, tumor formation, and general pathology. Several techniques have been developed to study biological structure in 3D like serial block-face ...
regarding cell size and shape, the composition of the extracellular matrix, the types of cell–cell junctions, the presence of specific membrane-bound organelles and the organization of the cytoskeleton. We further highlight essential disparities in important cellular processes such as signal ...

The application and further development of the GBA theory may foster an enhanced theoretical understanding of how physicochemical constraints determine the fitness costs and benefits of cellular organization. Moreover, the explicit expressions for the marginal fitness costs and benefits of cellular concentrat...
(the feature shape is added to the feature model of the manufacturing view, reducing the inconsistency between the feature models of the part detail and manufacturing), and organization (selection of faces relative to which the feature is positioned, based on specific information from the feature ...
In contrast to SPPL2c which may change Golgi morphology, in cells overexpressing SPP especially the ER is affected. SPP, but not its catalytically-inactive mutant, induces a re-organization of the ER characterized by the formation of densely packed, but highly dynamic ER clusters [52]. This ...

Buildings are constructed by architects and foremen who follow a plan and oversee the entire process. Cells have no master builder. Rather, cells are made of “smart bricks” that somehow know where they should be. This process of self-organization is very poorly understood and is a major ...
