proliferation meaning in biology

These changes can cause the the pathway to be stuck in the "on" position.16 The "on" signal leads to cell growth and proliferation. Given that cell proliferation involves an increase in the number of cells, the number of cells present during this process is measured as a function of time. Hamilton (ON): BC Decker; 2003. What does overproliferation mean? Proliferate came about in 1873 as a back-formation of "proliferation." The basic principle of all cell proliferation is the detection of cell viability and the measurement of the number of cells or the changes in the rate of division of cells. We would like to show you a description here but the site won’t allow us. For this, different antibodies are produced that are targeted at different antigens found in proliferative cells in different stages. Therefore, this region is variously called like growth zone, area of proliferation or budding zone, etc. Molecular Cell Biology 5th ed - Lodish et al. Sunderland (MA): Sinauer Associates; 2000. For biology , cell proliferation is one of the disorders that can occur in the process of evolution after cancer .cells grow and divide out of control, spreading to other parts of the body by metastasis and invading adjacent tissues.Cell proliferation can be seen with a microscope or with the use of cytometers, among other methods. Medical Definition of proliferation 1 a : rapid and repeated production of new parts or of offspring (as in a mass of cells by a rapid succession of cell divisions) b : a growth so formed Some of the common factors that influence cell proliferation include; Save my name, email, and website in this browser for the next time I comment. Proliferation definition, the growth or production of cells by multiplication of parts. Therefore, RAS overexpression and amplification can lead to continuous cell proliferation, which is a major step in the development of cancer.17 Cell division is regulated by a balance of positive and negative signals. Ability to Metastasize (Spread) Normal cells stay in the area of the body where they belong. 12.3 Adaptive Immunity ... meaning that it can recognize, by binding, a specific molecule or antigen (discussed below). ... 2 (Biology) of, relating to, or contained within the nucleus of a cell In a population of cells the proliferation activity can be described by means of the probability density for the proliferation protein; e.g., phosphorylated form of the extracellular signal-regulated kinase (ERK). The increase in cell number results via a sequence of steps involving cell growth and cell division. However, the process of abnormal cell proliferation in cancerous cells results in the formation of tumors that can be either benign or malignant. As with B cells, the clone includes active T C cells and inactive memory T C cells. “Coordinating cell proliferation and differentiation: Antagonism between cell cycle regulators and cell type-specific gene expression.”. eLS. proliferate + - ion 1855–60 WordReference Random House Learner's Dictionary of American English © 2020 Chapter 3.Available from: Andreeff M, Goodrich DW, Pardee AB. Schonrock, Kuhlmann, Adler, Bitsch, & Bruck. proliferate: ( prō-lif'ĕr-āt ), To grow and increase in number by means of reproduction of similar forms. Abnormal cell proliferation is indicated by the over-proliferation of cells and accumulation of such cells in an abnormal fashion. The process is balanced by cell division and cell differentiation or cell death, which maintains an appropriate number of cells in the body. Cell proliferation plays a vital role in regular tissue and cellular homoeostasis for proper growth, development, and maintenance of organism.
