Talk:Bone marrow

message: The article does not state whether bone marrow is present only in mammals or also in other classes of animals. Please amend. 74.85.71.228 (talk)  —Preceding undated comment added 05:02, 6 December 2010 (UTC)

message: "The tissue of bone marrow, where pluripotential hematopoietic stem cells produce blood cells, is called "myeloid tissue". Disruption of the normal myeloid tissue by cancer is the cause of two forms of leukemia." Actually, the marrow contains myeloid and lymphoid cells. All forms of leukemia (not just the myeloid forms) originate in the bone marrow. I've revised this sentence - comments? MastCell 04:33, 1 August 2006 (UTC)

message: Just curious as to how the blood cells made by the marrow get into the blood stream?
:As the cells mature, they lose various surface "adhesion" molecules that make them "stick" to the bone marrow, and they float loose into the blood. That's a vague hand-waving explanation that will probably get me laughed at, but that's the general idea. MastCell 15:51, 17 August 2006 (UTC)
thread_title:  how bone marrow works? 

message: Could someone clarify the purpose of bone marrow? Why did we evolve bone marrow? I can somehow deduce this from the "type of cells" but its somewhat vague and I would expect this explanation in the summary.

thread_title:  Purpose of bone marrow? 

message: The intro says that bone marrow is the place where blood cells originate, but is that true for yellow marrow? The difference between yellow and red marrow should be explained in the article. AxelBoldt 22:19, 15 October 2006 (UTC)
replies: text: Yellow marrow is just marrow with fat in it. - Nunh-huh 01:06, 16 October 2006 (UTC)

text: For what little I've read, there's a definite difference between red and yellow that needs explication.  As I understand, we start developmentally with red marrow and, as we age, develop yellow marrow.  Yellow marrow also either doesn't produce blood cells at all or produces only a few kinds.Satarnion 03:33, 17 October 2006 (UTC)

text: Agree, and the phrasing of this article is misleading. In fact, much of this article seems to be written by someone with fairly superficial grasp on the topic. I will work to expound on this red/yellow distinction in the future. Dr G (talk) 20:41, 27 December 2017 (UTC)
thread_title:  Difference between red and yellow marrow? 

message: This article is not only poorly written (alas most of Wikipedia is), but is also biased toward humans. Is it not true that most non invertebrate life has this sort of tissue? Perhaps an issue of unbiasing this article could be acomplisherd? Ask D.N.A.- Peter Napkin (talk) 04:40, 16 March 2008 (UTC)
replies: text: I agree with this assessment, but I don't know enough about marrow to revise effectively.  Marrow is clearly present in all mammalia; not in fish (though they may have a cold-blooded equivalent); I don't know about birds (I think they're hollow-boned, though, which would seem to preclude marrow?)  anyone with any real knowledge of this out there?  --Ludwigs2 04:14, 17 February 2009 (UTC)

thread_title:  Poorly written 

message: Bone marrow's culinary use really deserves its own article, not a two sentence quip as a subheading. Anyone with sufficient knowledge to write it should go for it, IMO, as it's becoming increasingly popular in the US as Americans slowly realize that it is okay to eat things that aren't chemical-filled, prepackaged crap.  —Preceding unsigned comment added by 70.20.18.122 (talk) 22:34, 15 August 2008 (UTC)

thread_title:  donating bone marrow 

message: I know bone marrow donation is encouraged, but the External Links to marrow donation centers don't seem appropriate.  They're not providing more information on bone marrow, they're advertising.  Unless I get any strenuous objections, I'm removing all marrow donation links for violation of WP:ADS. --ShadowRangerRIT (talk) 21:21, 28 October 2009 (UTC)
replies: text: Rather than wait, I decided to remove it immediately.  Every entry was either advertising for marrow donors or, in two odd cases, recipes for food made with marrow. None of it was appropriate for this article. --ShadowRangerRIT (talk) 21:26, 28 October 2009 (UTC)
replies: text:  I completely agree with your removal of the links. However, we should do some digging around and see if there's a "national" site for bone marrow disease & donation (like cancer's "national" site is the National Cancer Institute, etc.).
There are several national sites.  I've heard about this issue because my nephew's son has a disease that will need a bone marrow donation.  you can find several links to various national sites for more information at www.hope4noah.org (the site that my nephew and his wife have established recently).  The links were helpful.   I wonder if a collection of links could be added or at least a mention in the article cold be made to note that there is an ideal time for bone marrow donation... between 18 and 60 according to one site that is linked to http://www.hope4noah.org.
\\about the assertion that the donation sites "aren't providing more information on bone marrow," perhaps you have not had an opportunity to look at some of the sites.  The graphic images are quite helpful in understanding the process.  in particular you can see www.dkmsamericas.org/sites/default/files/iframes/bonemarrowdonation to see a helpful graphic and explanation of the process of bone marrow donation.  The wikipedia article does not make it clear that donation can change lives.  perhaps at least some graphic images can be 
the prohibition on advertising is certainly admirable.  Psychological investigation of what it takes to inform many people indicates that a measure of persuasion is often needed, above the information-sharing that takes place on most wikipedia sites.  perhaps the justification for including some of the bone marrow sites would be to show examples of the high level of generosity and good will that takes place.

thread_title:  anyone eat bone marrow? 

message: Bone marrow as food has been completely removed from the aricle. If it is supposed to be a purely medical article, there should be a second article about that kind of food.
In Germany for example, bone marrow balls for soup are a very common thing, you can buy it in most supermarkets.
Look at the German articles about bone marrow as food:
# DE:Mark (Lebensmittel) – "marrow (food)"
# DE:Markklößchen – "bone marrow balls"
Translation of the introduction of the first German article:
:"Mark (marrow) is the soft content found inside of hollow bones. In cuisine the yellow bone marrow of long bones ("Knochenmark" – bone marrow) is used as well as the spinal cord ("Rückenmark" – spinal marrow) – especially from cows and calves."
Translation of the introduction of the second German article:
:"Markklößchen ("bone marrow balls") (in Austria also Markknödel) are little balls/dumplings of white bread and bjsasKLone marrow or spinal cord/marrow from cow or calf, which are served in soups.
