Organ culture is the cultivation of either whole organs or parts of organs in vitro. [1] It is a development from tissue culture methods of research, as the use of the actual in vitro organ itself allows for more accurate modelling of the functions of an organ in various states and conditions.
Animal testing, also known as animal experimentation, animal research, and in vivo testing, is the use of non-human animals, such as model organisms, in experiments that seek to control the variables that affect the behavior or biological system under study.
Scientists around the country are racing to learn how to use animal organs to save human lives, and bodies donated for research offer a remarkable rehearsal. The latest experiment announced ...
An organ-on-a-chip (OOC) is a multi-channel 3-D microfluidic cell culture, ... However, experiments on animals are lengthy, expensive and controversial. For example ...
The transplantation of vital organs in the experiment Vladimir Petrovich Demikhov ( Russian : Владимир Петрович Демихов ; 31 July 1916 – 22 November 1998) [ 1 ] was a Soviet Russian scientist and organ transplantation pioneer, who performed several transplants in the 1940s and 1950s, including the transplantation of a ...
An organoid is a miniaturised and simplified version of an organ produced in vitro in three dimensions that mimics the key functional, structural, and biological complexity of that organ. [1] It is derived from one or a few cells from a tissue , embryonic stem cells , or induced pluripotent stem cells , which can self-organize in three ...
Organography as a scientific study starts with Aristotle, who considered the parts of plants as "organs" and began to consider the relationship between different organs and different functions. In the 17th century Joachim Jung, [ 1 ] clearly articulated that plants are composed of different organ types such as root, stem and leaf, and he went ...
