A chemically defined medium (also known as synthetic medium) is a growth medium suitable for the in vitro cell culture of human or animal cells in which all of the chemical components are known. Standard cell culture media commonly consist of a basal medium supplemented with animal serum (such as fetal bovine serum, FBS) as a source of ...
DFINE, Inc. was an American medical device company with headquarters in San Jose, California. [4] It was known for its development of minimally invasive therapeutic devices built upon a radiofrequency platform for the treatment of spinal diseases. [5]
Cell growth refers to an increase in the total mass of a cell, including both cytoplasmic, nuclear and organelle volume. [1] Cell growth occurs when the overall rate of cellular biosynthesis (production of biomolecules or anabolism) is greater than the overall rate of cellular degradation (the destruction of biomolecules via the proteasome, lysosome or autophagy, or catabolism).
Cell engineering is the purposeful process of adding, deleting, or modifying genetic sequences in living cells to achieve biological engineering goals such as altering cell production, changing cell growth and proliferation requirements, adding or removing cell functions, and many more.
The most common simplified overview description of the B cell differentiation pathway involves the following steps: an antigen interacts with the corresponding surface membrane immunoglobulin after which the B cell begins expressing receptors for growth factors secreted by T cells (BCGFs and IL-2), after these factors bind, the lymphocytes ...
Diauxic growth, diauxie or diphasic growth is any cell growth characterized by cellular growth in two phases. Diauxic growth, meaning double growth, is caused by the presence of two substrates (usually sugars) in a culture growth media, when the microbial cells are capable of faster growth on one of these substrates.
Hair growth vitamins and supplements work by nourishing the body with the necessary vitamins and minerals for improved hair growth, such as biotin, vitamin D, vitamin E, vitamin C, iron, zinc, and ...
While growth factor implies a positive effect on cell proliferation, cytokine is a neutral term with respect to whether a molecule affects proliferation. While some cytokines can be growth factors, such as G-CSF and GM-CSF, others have an inhibitory effect on cell growth or cell proliferation.
