Can stem cells rebuild cartilege?

Yes, but!: Many types of stem cells have been made to form cartilage (including stem cells from fat, marrow, amnion, blood). I have even personally done much research on this. However, the problem is that we have no good way of placing the cartilage back into the knee (or other joint) and keep it in place while the body heals. There are encouraging trials, but no definitive solutions yet. ...Read more

Where are stem cells found?

Where are stem cells found?

Everywhere we look: Stem cells are cells which can, under certain conditions, produce more differentiated, tissue-specific daughter cells. There are stem cells in the skin, the heart, the circulating blood, the bone marrow, the fat -- just about anywhere. ...Read more

Do doctors get non-embryonic stem cells from bone marrow?

Do doctors get non-embryonic stem cells from bone marrow?

Yes: Mostly hematopoietic (blood) cells and a few mesenchymal (mscs) can be obtained from bone marrow aspiration. Trends in most non-blood applications is to use fat tissues, which have many more mscs that bone marrow. Choice of which depends on specific conditions being treated. ...Read more

Does embryonic stem cells came from the bone marrow?

Does embryonic stem cells came from the bone marrow?

Stem cells: There are many types of stem cells that reside in the bone marrow. They technically aren't "embryonic" stem cells, since those by definition are derived from an embryo. The stem cells that exist in your bone marrow, however, share many of the characteristics of embryonic stem cells. ...Read more

Can stem cell research regrow a man's foreskin?

Can stem cell research regrow a man's foreskin?

Poss.could but won't: There are many much more important organs & tissues which require or have ongoing stem cell reasearch. Stem cells to restore foreskin, in my opinion, would be at bottom of list. Such researc h is very expensive, would never pay for itself nor would researchers undertake this work which they would consider frivolous & unnecessary. ...Read more

Why are umbilical cord stem cells sometimes uses along with donor cells in an allogeneic bone marrow transplant?

Why are umbilical cord stem cells sometimes uses along with donor cells in an allogeneic bone marrow transplant?

One of the other: Stem cells can be obtained from 3 different sources: from Bone marrow of the Donor, blood of the donor or stem cells from umbilical cord. But we have to give an adequate number(Dose) of stem cells in order to have full protection. So combining them may only be needed because of inadequate number of stem cells from one of the sources ...Read more

How are adult stem cells and embryonic stem cells different?

How are adult stem cells and embryonic stem cells different?

Stem Cells: Check out regenexx.Com for more info. Basically adult stem cells are usually from your own blood, fat or bone marrow. Embryonic stem cells are from fetal tissue and umbilical cord blood and tissue but are not your own unless you had this harvested when you were born. ...Read more

Can frozen embryo provide stem cells someday?

Can frozen embryo provide stem cells someday?

Yes if they want: Most couples who have surplus frozen embryos after completing their family choose to discard them, but recently many couples have not felt comfortable with this option and instead choose to donate them to stem cell research so that these embryos can be utilized to help others. ...Read more

How are stem cells extracted?

How are stem cells extracted?

Depends on cell type: There are a variety of stem cell types, including embryonic, which reside in a 4 day old embryo; vs.adult stem cells, which reside in mature tissues. Bone marrow stem cells are the only type in routine use and may be harvested from marrow aspirations, peripheral blood mobilization, or umbilical cord blood. Induced progenitor cells may be made in the lab from other cell types through gene therapy. ...Read more

Does stem cell research help diseased arteries?

Does stem cell research help diseased arteries?

Limited to Date: For surgical replacement of diseased arteries, taking cells from an intended recipient to grow in lab over months to populate a scaffold structure (e.g. Pig artery with cells washed away using detergents) is being done; limited, slow & does nothing about intrinsic disease. For the original disease, best is to optimize the ds drivers within each of us: lipoproteins, blood sugar, bp, no smoking etc. ...Read more

What differentiates embryonic stem cells from other stem cells?

What differentiates embryonic stem cells from other stem cells?

Origin: Embryonic stem cells are derived from fertilized eggs created to help couples who have difficulty conceiving. This is "murder" according to some religionists. Other stem cells come from other sources. However, since the striking success of embryonic stem cells in early studies on wet macular degeneration, even the conservative presidential candidate no longer seems opposed to their use. ...Read more

How could stem cell therapies help restore nerves damage resulting from spina?

Integration : Stem cells are pluripotent cells meaning they can be programmed to be anything. The problem or difficulty is the integration and fidelity to a specific site of interest like the spinal cord. There are a number of research going on that someday there would be a cure to the most devastating ailments. ...Read more
