Why is self renewal of stem cells important?

Self-renewal is the process by which stem cells divide to make more stem cells, perpetuating the stem cell pool throughout life. Self-renewal is division with maintenance of the undifferentiated state. This requires cell cycle control and often maintenance of multipotency or pluripotency, depending on the stem cell.

Why are stem cells important?

Stem cells are important for living organisms for many reasons. In the 3- to 5-day-old embryo, called a blastocyst, the inner cells give rise to the entire body of the organism, including all of the many specialized cell types and organs such as the heart, lung, skin, sperm, eggs and other tissues. In some adult tissues, such as bone marrow, muscle, and brain, discrete populations of adult stem cells generate replacements for cells that are lost through normal wear and tear, injury, or disease.

Graft-versus-tumor occurs when white blood cells from your donor (the graft) attack any cancer cells that remain in your body (the tumor) after high-dose treatments. This effect improves the success of the treatments.

What happens if you have an allogeneic transplant?

If you have an allogeneic transplant, you might develop a serious problem called graft-versus-host disease. Graft-versus-host disease can occur when white blood cells from your donor (the graft) recognize cells in your body (the host) as foreign and attack them. This problem can cause damage to your skin, liver, intestines, and many other organs. It can occur a few weeks after the transplant or much later. Graft-versus-host disease can be treated with steroids or other drugs that suppress your immune system.

Why do stem cells make sense?

If you have a certain type of blood cancer, for example, transplantation with blood-forming stem cells makes sense, as the treatment requires those specific cells to do exactly what they are designed to do. If you have diabetes, receiving a blood-forming stem cell treatment doesn’t make sense, because the problem is in the pancreas rather than in the blood itself. Without significant and careful manipulation in the lab, tissue-specific stem cells do not generate cell types found outside of their home tissues.

What happens when you get stem cells from a donor?

When you get stem cells from a donor or cord blood, there’s a risk of something called graft-versus.-host disease. It’s when your body fights to get rid of the new cells, or the cells launch an attack against you. It could happen right after the transplant or not until a year later.

How do you get autologous stem cells?
