An electronic book, also known as an e-book or eBook, is a book publication made available in digital form, consisting of text, images, or both, readable on the flat-panel display of computers or other electronic devices. Although sometimes defined as "an electronic version of a printed book",some e-books exist without a printed equivalent. E-books can be read on dedicated e-reader devices, but also on any computer device that features a controllable viewing screen, including desktop computers, laptops, tablets and smartphones.

Exploring and Engineering the Cell Surface Interface | Science - Nanoscale Engineering at the Surface. Topographic reaction (, reaction to the surface landscape) of cells to micrometer-range features such as grooves, ridges, and wells has been well established for decades ( 27 ).

Architecture and biosynthesis of the Saccharomyces cerevisiae cell wall - The wall gives a Saccharomyces cerevisiae cell its osmotic integrity; defines cell shape during budding growth, mating, sporulation, and pseudohypha formation; and presents adhesive glycoproteins to other yeast cells. The wall consists of β1,3- and β1,6-glucans, a small amount of chitin, and many different proteins that may bear N- and O

Cell Shape and Size: : Definition and Factors - Embibe - Cells rarely remain in a spherical form within an organism. They are flattened (epithelial cells), spindle-shaped (muscle cells), spider-shaped (nerve cells), and other shapes. A cell's size and shape are determined by four factors: 1. Surface-volume ratio 2. Nucleocytoplasmic ratio 3. Rate of cellular activity 4. Cell associations. Surface

Cytoskeleton: Anatomy, Function, and Structure - ThoughtCo - Cytoskeleton Function. The cytoskeleton extends throughout the cell's cytoplasm and directs a number of important functions. It helps the cell maintain its shape and gives support to the cell. A variety of cellular organelles are held in place by the cytoskeleton. It assists in the formation of vacuoles

Sculpting the surface: Structural patterning of plant epidermis - Finally, cell shape and cuticular ornamentation not only differ between species but can also vary in both space and time across an epidermis. The surface of developing organs changes as cells differentiate, and cells located in different regions can acquire distinct fates, creating higher-order patterns (Figure 1G). Detailed examinations of

They function in maintaining the elliptical cell shape. Following primary wall synthesis, Golgi-derived materials accumulate

Cell Adhesion: The Molecular Basis of Tissue Architecture and - Cell adhesion is crucial for the assembly of individual cells into the three-dimensional tissues of animals. Cells do not simply "stick" together to form tissues, but rather are organized into very diverse and highly distinctive patterns. A variety of cell adhesion mechanisms are responsible for assembling cells together and, along with their connections to the internal cytoskeleton

Cell morphology drives spatial patterning in microbial ... - PNAS - As predicted by our model, cell types strongly sort by shape, with round cells at the top of the colony and rod cells dominating the basal surface and edges. Our work suggests that cell morphology has a strong impact within microbial communities and may offer new ways to engineer the structure of synthetic communities

The Plant Cell Wall - Molecular Biology of the Cell - NCBI Bookshelf - The plant cell wall is an elaborate extracellular matrix that encloses each cell in a plant. It was the thick cell walls of cork, visible in a primitive microscope, that in 1663 enabled Robert Hooke to distinguish and name cells for the first time. The walls of neighboring plant cells, cemented together to form the intact plant (Figure 19-68), are generally thicker, stronger, and, most

A dynamic cell adhesion surface regulates tissue architecture in growth - The architecture and morphogenetic properties of tissues are founded in the tissue-specific regulation of cell behaviors. In endochondral bones, the growth plate cartilage promotes bone elongation via regulated chondrocyte maturation within an ordered, three-dimensional cell array. A key event in the process that generates this cell array is the transformation of disordered resting

Cell surface mechanics and the control of cell shape, tissue patterns - Many signalling pathways have been shown to control cell shape and cell surface mechanics. Recent insights from diverse disciplines point to adhesion and cortical tension as regulators of cell

Cell Responses to Surface and Architecture of Tissue Engineering - 1. Introduction. Tissue engineering is an interdisciplinary field that combines the knowledge and technology of cells, engineering materials, and suitable biochemical factor to create artificial organs and tissues, or to regenerate damage tissues (Langer & Vacanti, 1993).It involves cell seeding on a scaffold followed by culturing in vitro prior to implantation in vivo

Cells: why shape matters - Science in School - A key finding is that the actomyosin cortex controls cell shape by creating tension in the cell surface, rather like the tension in the skin of a balloon. If the myosin motors are inhibited or the actin filaments are broken down, the tension is lost and the cell surface forms bulges, disrupting its shape. In many cases, the shapes of cells are

Prokaryote structure (article) | Khan Academy - Flagella and some pili are used for locomotion, fimbriae help the cell stick to a surface, and sex pili are used for DNA exchange. Most prokaryotic cells have a single circular chromosome. ... This structure maintains the cell's shape, protects the cell interior, and prevents the cell from bursting when it takes up water

The cytoskeleton (article) | Khan Academy - Flagella (singular, flagellum) are long, hair-like structures that extend from the cell surface and are used to move an entire cell, such as a sperm. If a cell has any flagella, it usually has one or just a few. Motile cilia (singular, cilium) are similar, but are shorter and usually appear in large numbers on the cell surface. When cells with

The basics, benefits and risks of cell-based architecture - The first major benefit of the cell-based architecture approach is that it is resilient. The independent nature of these cells helps development teams perform staged rollouts, blue-green deploys and other incremental approaches to updates and deployments. This makes rollbacks easier as well: Simply create an older version of the cell in the

Keeping Cells in Good Shape | NASA - The Cell Shape and Expression, or Cytospace, investigation examined how physical forces - including shear stress, stiffness, surface tension, and gravity - change the relationships among these proteins, interfering with cell architecture and changing the geometric form, or shape, of the cell. These changes in cell shape in turn affect

Cell shape and tension alter focal adhesion structure - The cells can only adhere to the pattern and change their cell shape accordingly [21]. The choice of cell shape determines the extent of cell spreading as well as the cytoskeletal and adhesive tension [22]. Actomyosin contractility, actin polymerisation and gene expression are strongly dependent on the shape of the cell [23], [24], [25]

Appreciating the role of cell shape changes in the mechanobiology of - Cell shape changes often require modifications of cell spreading, which can result in nuclear flattening in concert with extension of the wrinkled nuclear surface. Elongation of the cell shape was shown to trigger major nuclear deformations through a spatial reorganization of ventral actomyosin fibers that exert lateral compressive forces on

Frontiers | Cells Dynamically Adapt to Surface Geometry by Remodeling - Cells probe their environment and adapt their shape accordingly via the organization of focal adhesions and the actin cytoskeleton. In an earlier publication, we described the relationship between cell shape and physiology, for example, shape-induced differentiation, metabolism, and proliferation in mesenchymal stem cells and tenocytes. In this study, we investigated how these cells organize

Multiscale analysis of architecture, cell size and the cell cortex - Perturbing cell-cell adhesion can also disrupt the normal sorting processes that position epidermal cells on the outer surface of the zebrafish embryo (Manning et al., 2010). Embryos of the African claw-toed frog Xenopus laevis have been extensively studied with respect to the mechanics involved in gastrulation, neurulation, heart formation and
