In vitro studies permit a species-specific, simpler, more convenient, and more detailed analysis than can be done with the whole organism. Just as studies in whole animals more and more replace human trials, so are in vitro studies replacing studies in whole animals.
This is a laboratory rat with a brain implant, that was used to record in vivo neuronal activity. Studies that are in vivo (Latin for "within the living"; often not italicized in English [1] [2] [3]) are those in which the effects of various biological entities are tested on whole, living organisms or cells, usually animals, including humans, and plants, as opposed to a tissue extract or dead ...
Typically, the parameter derived from the biological property is AUC or Cmax, while the physicochemical property is the in vitro dissolution profile. The main roles of IVIVC are: To use dissolution test as a surrogate for human studies. To supports and/or validate the use of dissolution methods and specifications.
Artificial reproduction is the re-creation of life brought about by means other than natural ones. It is new life built by human plans and projects. Examples include artificial selection, artificial insemination, in vitro fertilization, artificial womb, artificial cloning, and kinematic replication.
Serial passage can either be performed in vitro or in vivo. In the in vitro method, a virus or a strain of bacteria will be isolated and allowed to grow for a certain time. After the sample has grown for that time, part of it will be transferred to a new environment and allowed to grow for the same period.
Ex vivo brainstem: (A) coronal view displaying the anterior portion of the tissue sample, (B) sagittal view displaying the left-hand side of the tissue sample [1]. Ex vivo (Latin: "out of the living") literally means that which takes place outside an organism. [2]
It was coined in 1987 as an allusion to the Latin phrases in vivo, in vitro, and in situ, which are commonly used in biology (especially systems biology). The latter phrases refer, respectively, to experiments done in living organisms, outside living organisms, and where they are found in nature.
In vitro may also refer to: In vitro fertilization, a process of fertilization where an egg is combined with sperm outside the body; In Vitro, a fictional genetically engineered subspecies of humans in the science fiction television series Space: Above and Beyond; In Vitro, a scientific journal
