What's the difference between Ex Vivo and In Vitro ?

Answer 1

When scientists use Ex Vivo they mean the same thing as In Vitro, which is outside the organsims in a tissue culture dish. However, for Ex Vivo experiments whatever manipulation has been done will find its way back into the organism (i.e. they put it back and then the experiment really begins). An example would be harvesting bone marrow hematopoietic stem cells, labeling these cells with a retrovirus that overexpress's a gene of interest, and then injecting those cells that had been infected Ex Vivo back into the organism. If it were an In Vitro experiment they would not have injected the cells back into the organism, but rather tried to do something with them in culture.

Answer 2

Ex vivo and invitro have very similar meanings, and can be interchangable in many situations.

Ex vivo means it happens outside of a living organism, but can mean that you are working with a larger, organized structure from another organism, ie., using a whole liver removed from a laboratory animal in an experiment.

In vitro means within an artificial setting, and literally means 'within glass.' This is often used when describing something that has been maintained for some time outside of a living organism, such as immortalized cell lines, or other types of cultures.

Answer 3

Ex vivo (Latin: out of the living) means that which takes place outside an organism. In science, ex vivo refers to experimentation done in or on living tissue in an artificial environment outside the organism. The most common "ex vivo" procedures involve living cells or tissues taken from an organism and cultured in a laboratory apparatus, usually under sterile conditions for a few days or weeks. The living cultured cells serve as models of the whole organism, reducing the need for vivisection
Ex vivo studies are usually performed in vitro, although the use of these two terms is not synonymous.

In vitro (Latin: (with)in 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.

Answer 4

Ex Vivo means the same thing as In Vitro, that is, in the body of the organism used for the experiment.

Answer 5

Ex Vivo has the same meaning as In Vitro,it means something biological like fertilization or enzymatic action happening outside the body,like in a test tube or a petri dish.

Answer 6

Ex Vivo is ouside the body

In Vitro - the fertilization is outside the body but the gestation is inside the body.

Answer 7

i think in vitro means like in a petri dish. like in vitro... in dish. its got to be latin or something. ex vivo is outside of the body?
