Abstract How do the cells in our body reconfigure their shape to achieve complex tasks like migration and mitosis, yet maintain their shape in response to forces exerted by, for instance, blood flow and muscle action? Cell shape control is defined by a delicate mechanical balance between active force generation and passive material ...

Star-shaped cells of the amacrine cell layer
Cell Biology International Reports, 1988Using silver impregnation techniques and light microscopy we have described a new type of interneuron in the adult chicken retina. These cells are located in the innermost level of the INL. Expansions arise from the basal portion of the perikaryon and ascend from there, ending in the inner third of the INL.

Stimulation of Spheroidal Cells - The Role of Cell Shape
IEEE Transactions on Biomedical Engineering, 1976The behavior of spheroidal cells in an applied uniform field is examined in order to gain insight into the role of cell shape in the electrical activity of biological cells. The responses of cells having different eccentricities but the same height in the direction of stimulation are compared.

Drebrin is localized in actin-rich regions of neuronal and non-neuronal cells. In mature neurons, its localization is strictly restricted to the postsynaptic sites. In order to understand the function of drebrin in cells, many studies have been performed to examine the effect of overexpression or knocking down of drebrin in various cell types ...

Journal of Theoretical Biology, 1972
Abstract A simple physical explanation is presented for the shape of normal and pathological mammalian red cells. Experiments with specially prepared tennis balls are described which support the author's major contentions. Photographic plates show the tennis balls after they have taken up various shapes reminiscent of normal and pathological red ...

Cell shape development in plants
Trends in Plant Science, 2004The shape of a plant cell has long been the cornerstone of diverse areas of plant research but it is only recently that molecular-genetic and cell-biological tools have been effectively combined for dissecting plant cell morphogenesis. Increased understanding of the polar growth characteristics of model cell types, the availability of many ...

Paratene theory of the shapes of cells
Journal of Theoretical Biology, 1967Abstract Paratenes are one-dimensional circular linkage groupings of cell organelles composing the cell surface of Paramecium. In cell division, pre-existing paratenes serve as supertemplates for the replica paratenes which form anteriorly to them thereby enlarging the surface area in an orderly and predictable manner.

Current Opinion in Plant Biology, 1998
Plant cells have a variety of shapes crucial for their functions, yet the mechanisms that generate these shapes are poorly understood. Genetic dissection of the trichome (plant hair) branching pathway in Arabidopsis, has uncovered mechanisms and identified genes that control plant cell morphogenesis.

Shape and Shape Transformations of Heated Human Red Cells
Journal of Experimental Biology, 1949ABSTRACT The action of temperatures above 48° C. on the red cell is usually regarded as a classical example of the irreversible effects of injury, the lysis which follows being attributed to a surface membrane becoming permeable because its lipid components are melted or because its protein components become denatured.
