A substance that promotes the growth of micro-organisms. Laboratories most commonly use agar gel, made from seaweed. Dead tissue is an ideal culture medium. Never use substances to clean a piercing that can kill tissue, e.g. alcohol, for the dead tissue then becomes a culture medium for bacteria.
The fluid in which cells or tissues, including eggs, sperm and embryos, are grown. It consists of water, salts and nutrients. Different media have turned out best for different purposes. In the early days of in vitro fertilisation, several different media seemed to produce equal results: examples included Ham's F10, Whittingham's T6. Quinn's medium (said to be based on human tubal fluid, though in reality different to the fluid in the fallopian tube) produced better results than the first generation media. Today's third generation media, or stage specific media, give superior results and are used increasingly. Plural: culture media.
The substance that provides nutritional and environmental support for eggs, sperm and embryos in the laboratory
(bacteriology) a nutrient substance (solid or liquid) that is used to cultivate micro-organisms
a nutrient substance, either solid or liquid, used for the cultivation, isolation, identification or storage of microorganisms or cells
A liquid, complex mixture containing nutrients, electrolytes etc. used to maintain cells in vitro.
Any nutrient system for the artificial cultivation of bacteria or other cells; usually a complex mixture of organic and inorganic materials.
The nutrient materials required for growth of microorganisms such as bacteria and fungi, also used for plant and animal tissue growth.
The fluid that surrounds cells in a cell culture. It has nutrients to feed and sustain the cells. Scientists can add other ingredients to help make the cells grow into specialized cells.
The broth that covers cells in a culture dish, which contains nutrients to feed the cells as well as other growth factors that may be added to direct desired changes in the cells.
special fluid in which eggs, sperm and embryos may survive and grow
The fluid solution used in the laboratory to grow cells in vitro.
A culture medium is a substance on or in which microorganisms or cells can be grown. It contains nutrients and a favorable environment for the growth of microorganisms and cells.
A liquid or gel-like substance containing nutrients in which tissues are cultivated for scientific purposes; used in tissue culture.
