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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
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
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?
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
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
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 moreSee 2 more doctor answers
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
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
Experimental: Although positive results have occurred in annals treated with stem cells and two humans were recently reported to gain sensation it is still experimental with nothing yet reaching the stage of clinical trials as yet. ...Read more
Can embryonic stem cell be preserved the same way as cord blood stem cell? Possible to retrieve single stem cell clinically in IVF w/o harming embryo?
No: Technology not currently developed to support this strategy. ...Read more
