It is possible to grow meat by using stem cells, and the first \"in vitro beefburger\" was introduced to the public in August 2013.

"In vitro" is a phrase used to denote something which has been developed or tested in a lab/petry dish, rather than in it's normal environment. For example, in vitro fertilization (IVF) involves fertilizing the egg with the sperm in a petry dish, then implanting the fertilized egg back into the women's uterus.

One of the most important things to know about things tested or developed "in vitro" is that many things which occur in petry dish or lab circumstances do not work in the same way when tested out under "in vivo" conditions (the conditions the reaction would normally occur in - ie. non lab conditions).

In vitro meat is meat which has been grown in a lab (in a petry dish - not on an animal). It is still a very experimental process, however it has been shown to work.

what is the bioethical in in vitro fertilazation

Yes. In vitro means, "in glass" or "outside of the body", and In vitro pregnancy test is a test that is performed "outside" of the human body. In vitro fertilization is egg fertilization that is performed outside of the body. All home pregnancy tests are "in vitro".

The opposite of "in vitro" (literally in glass) is "in vivo" (in life).
