[edit] Fact check

Inserted by an anonymous user:

The stem cells which are produced by teratocarcinoma were used for medicinal purposes, but only in a few experiments. Per example, a teratoma producing nerval tissue helped restore the brain of a man suffering a stroke.

Does anyone have a reference to substantiate this? It sounds a bit tall to me; stem cells are being considered for Parkinson's, but AFAIK not for CVAs. JFW | T@lk 10:25, 10 Oct 2004 (UTC)

[edit] Pluripotent -> Totipotent

According to Robbins Pathologic Basis of Disease, teratomas arise from totipotent cells. Anyone any arguments for the 'pluripotent' as stated here in the first line?

I have not seen the term "pluripotent" in the medical literature on teratomas that I have read. The usual term is "totipotent". However, per Google the terms "pluripotent" and "totipotent" occur at a ratio of 5:1. And they mean essentially the same thing. 66.167.45.138 04:02, 26 January 2007 (UTC)

Pluripotent and totipotent are not the same thing. Totipotent cells can form trophectoderms while pluripotent cells can't

Fair enough. In the context of this page, though, the question is: does teratoma derive from one or the other cell type, or both? Una Smith 14:36, 8 April 2007 (UTC)

[edit] Incidence of teratomas by location

I removed the following list item because it hints at a larger table, but has only one entry from the bottom of that table, which just looks a bit odd sitting by itself out there. It's kind of like saying, "1% of teratomas are gastric", which is sort of trivia without information about that other 99%. Really the solution is to have a complete table of teratoma incidence by location, but until that becomes available, I've moved the graf here.Collabi 19:42, 28 April 2007 (UTC)

[edit] External link

Why is http://health.groups.yahoo.com/group/teratomas/ being removed? Fred Bauder 01:26, 10 September 2007 (UTC)

Because it is without question external link spam. Someone else removed a link to another support group. I allowed that one because that group has a public archive. This one does not, so I do not know that it is in fact what its promoters purport it to be. I am not the only editor who has removed it, BTW. Are you a subscriber? If not, what is your interest? --Una Smith 16:15, 10 September 2007 (UTC)

Una,

How is it that you have decided unilaterally to classify this link as spam?

• Baby with a large facial teratoma cured by surgery (with photos)

It is without question not spam, it is the story of a little girl from California who suffered a large facial teratoma and was cured by surgery. It contains photos of the teratoma and may be of interest to Wikipedia readers who are interested in learning more about teratomas. There are no ads or references to objectionable material in the article or anywhere on the site, perhaps you deleted it in error.

I believe if you refer to Wikipedia's policy on external links, you will see that the story about the little girl with the teratoma fits the criteria of being an appropriate link.

Lastly, after reading this, I hope you are acting sincerely and netutrally regarding this issue. Above you mention that you allowed a link to another support group because it has a public archive, but from this, it appears as if it was you who added the link.

I am hoping that this is a misunderstanding and that your POV is neutral and within the spirit of Wikipedia.

[edit] picture suggestion

not sure how to add pictures, but i think this one would be good [1] —Preceding unsigned comment added by Mongreilf (talk • contribs) 16:05, 19 May 2008 (UTC)
