Encyclopedia > In vitro

In vitro (Latin: within the glass) refers to the technique of performing a given experiment in a test tube, or, generally, in a controlled environment outside a living organism. In vitro fertilization is a well-known example of this. Many experiments in cellular biology are conducted outside of organisms or cells; because the test conditions may not correspond to the conditions inside of the organism, this may result in inaccurate results. Consequently, such experimental results are often annotated with in vitro, in contradistinction with in vivo . For other uses, see Latin (disambiguation). ... A test tube (Sometimes culture tube) is a kind of laboratory glassware, composed of a fingerlike length of glass tubing, open at the top, sometimes with a rounded lip at the top, and a rounded U shaped bottom. ...

In vitro fertilization (IVF) is a technique in which egg cells are fertilized outside the mothers body in cases where conception is difficult or impossible through normal intercourse. ... Cell biology (cellular biology) is an academic discipline which studies the physiological properties of cells, as well as their behaviours, interactions, and environment; this is done both on a microscopic and molecular level. ...

This type of research aims at describing the effects of an experimental variable on a subset of an organism's constituent parts. It tends to focus on organs, tissues, cells, cellular components, proteins, and/or biomolecules. Overall, it is better suited for deducing the mechanisms of action (See in vivo for its description and respective merits). With fewer variables and perceptually amplified reactions to subtle causes, results are, generally, more discernible. Image File history File links Emblem-important. ...

The massive adoption of low-cost in vitro molecular biology techniques has caused a shift away from in vivo research which is more idiosyncratic and expensive in comparison to its molecular counterpart. Currently, in vitro research is both vital and highly productive. Molecular biology is the study of biology at a molecular level. ... In vivo (Latin for (with)in the living). ...

In vitro meat - Wikipedia, the free encyclopedia (782 words)
In vitro meat should not be confused with imitation meat, which can be a vegetarian food product produced from vegetable protein, usually from soy or gluten.
In vitro meat may be cleaner and less prone to disease than animals, provided that donor cells are not contaminated.
The in vitro meat would also be exempt from the growth hormones and antibiotics that are used on animals to, respectively, make them grow bigger and fight off the various infections that come from putting so many animals in close quarters for extended periods of time.
