Talk:Ex vivo

Thank you very much for at least this already very helpful stub! 78.49.72.166 (talk) 23:44, 17 February 2008 (UTC) (Chactory)

Could an explanation of the distinction between ex vivo and in vitro be added? Compare and contrast of an example. —Preceding unsigned comment added by 137.149.134.8 (talk) 23:39, 29 March 2008 (UTC)

This “stub” contains remarkably confusing ideas. The following can be cited: 1-On the one hand, it is stated that the expression… “ex vivo refers to experimentation … in an artificial environment… with the minimum alteration of natural conditions”. And, on the other, an ex vivo condition is exemplified as “measurements of … tissue properties …in various environments that may not be life-sustaining (…at extreme pressures or temperatures). Clearly these examples do not correspond to conditions of minimum alteration of natural conditions. 2-Another example refers to …”phantoms in imaging technique development”. Clearly this objects do not corresponds to living cells, tissues or organs. A “phantom” is an artificial (informatic) objetct designed in the field of medical imaging to evaluate, analyze, and tune the performance of various imaging devices. Thus, a phantom is not a living object but rather a “virtual” 2D o 3D object. 3-It is not clear what “realistic models for surgical procedure development” means. The expression “surgical procedure” does not refer to scientific research but to a technical procedure. 4-With regards to the statement “The term ex vivo is often differentiated from the term in vitro ("within the glass") in that the tissue or cells need not be in culture; these two terms are not synonymous”. It is advisable to sustain the notion with a authorized scientific reference. 5-On the one hand, it is stated that “The term ex vivo is often differentiated from the term in vitro ("within the glass") in that the tissue or cells need not be in culture..” and, on the other, that “ex vivo procedures often involve living cells or tissues taken from an organism and cultured…”. — Preceding unsigned comment added by Vladimir Flores (talk • contribs) 16:39, 1 March 2011 (UTC)

What is the distinction between in situ and ex vivo? (if any?) --JonathanWilliford (talk) 22:02, 5 March 2011 (UTC)


 * I've removed a lot of this confusing info and added more content around human tissue models and added references Zpuckr200 (talk) 11:44, 5 August 2022 (UTC)

Paragraph beginning "The term ex vivo..."
I tried cleaning this up, but there are a lot of grammatical problems making the paragraph difficult to read and the explanation unclear. Perhaps someone can clean it up? 148.177.1.211 (talk) 18:21, 28 April 2015 (UTC)

Arresting photo, but it's pure science fiction from the standpoint of therapy
The photo doesn't show any procedure typically performed in medicine, i.e., the removal of the brainstem from a living person. It cannot be kept alive and successfully put back in the person! Maybe someday??

Despite the image likely having been found in a search for the term "ex vivo", what is shown is probably a human autopsy specimen. Surely some image more representative can be found, like a free-use diagram of the procedure whereby lymphocytes are "taught to fight cancer"?-- Quisqualis (talk) 19:40, 20 February 2023 (UTC)
