When you get stem cells from a donor or cord blood, there’s a risk of something called graft-versus.-host disease. Younger stem cells are about 10 times more potent than that of older stem cells. These are the blood cell-forming adult stem cells found in bone marrow.

Stem cells are different from other cells in the body in three ways: They can divide and renew themselves over a long time
And some people find it morally troubling to use stem cells that come from embryos. Stem cells can develop into different cell types. Enough cells are usually collected for two transplantation procedures, especially for multiple myeloma. Advantages: Less risk of rejection or graft-versus-host disease, in which the new donor cells think your cells are foreign and attack them.

In a tandem (double autologous) transplant, you go through the above process twice instead of once, with a three- to six-month break in between. These embryonic stem cells are pluripotent.

These help people with cancer make new blood cells after their own hematopoietic stem cells have been killed by radiation therapy and chemotherapy. You receive conditioning treatment with chemotherapy and radiation. In March 2009, however, President Obama officially removed the restrictions placed by President Bush on federal funding for research on embryos. Please refresh the page and try again. For example, when placed in a petri dish with the proper nutrients, one cord stem cell will multiply into 1 billion cells in 30 days, whereas one adult stem cell will multiply into only around 200 cells in 30 days, according to a 2011 study published in the journal Orthopedics. Placental Tissue Stem Cells New York, There was a problem. In addition, adult stem cells may be subject to DNA abnormalities caused by sunlight, toxins and errors associated with making more DNA copies over the course of a lifetime, according to the National Institutes of Health (NIH). However, recent clinical trials show that using your own cells once, followed by reduced intensity conditioning treatment and then a transplant from a sibling, offers even longer remissions than tandem.
