Bioelectromagnetics, also known as bioelectromagnetism, is the study of the interaction between electromagnetic fields and biological entities. Areas of study include electromagnetic fields produced by living cells, tissues or organisms, the effects of man-made sources of electromagnetic fields like mobile phones, and the application of electromagnetic radiation toward therapies for the ...
Contact sites between the outer mitochondrial membrane and the ER is present in many organisms. [2] About 100 of these contact sites exist between the ER and mitochondria per yeast cell . [ 3 ] The fraction of ER that co-purifies with mitochondria, the so-called Mitochondria-associated endoplasmic reticulum membrane (MAM) has been extensively ...
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
Redvine (Brunnichia ovata) tendrils coil upon contact. In plant biology, thigmotropism is a directional growth movement which occurs as a mechanosensory response to a touch stimulus. Thigmotropism is typically found in twining plants and tendrils, however plant biologists have also found thigmotropic responses in flowering plants and fungi.
This delay between cell-cell contact and onset of proliferation inhibition is shortened as the culture becomes more confluent. Thus, it may be reasonably concluded that cell-cell contact is an essential condition for contact inhibition of proliferation, but is by itself insufficient for mitotic inhibition.
Cell signaling research involves studying the spatial and temporal dynamics of both receptors and the components of signaling pathways that are activated by receptors in various cell types. [ 55 ] [ 56 ] Emerging methods for single-cell mass-spectrometry analysis promise to enable studying signal transduction with single-cell resolution.
These molecules are an invaluable part of cellular communication, as a single ligand can be used for many integrins. Unfortunately, these molecules still have a long way to go in the ways of research. [20] Immunoglobulin superfamily are a group of calcium independent proteins capable of homophilic and heterophilic adhesion. Homophilic adhesion ...
Schematic of cell adhesion. Cell adhesion is the process by which cells interact and attach to neighbouring cells through specialised molecules of the cell surface. This process can occur either through direct contact between cell surfaces such as cell junctions or indirect interaction, where cells attach to surrounding extracellular matrix, a gel-like structure containing molecules released ...
