Stem Cell Research

A stem cell is the cell from the embryo, fetus, or adult that has, in some circumstances, the ability to reproduce itself for epic periods or, throughout the life of the organism, in the case of adult stem cells. It can also give specialized cells that make up the organs and tissues of the body. In the mid 1800s, it was discovered that stem cells are the building blocks of life. They also discovered that stem cells can create other cells. Federal Funding is limited to stem cell lines that already exist.

Embryonic stem cells were discovered in 1920 in chickens. Their human counterparts, however, were only isolated and reproduced in 1981. The funding doesn't support making new stem cell lines from already existing fertilized eggs. The U.S. Policy is an attempt at compromise; one that supports medical research, and at the same time eases the moral concerns of those opposing embryonic stem cell research.

Stem cells use is limitless. Stem cells have the potential to treat a large range of conditions and diseases around the world. Their ability to treat an enormous range of diseases rests on their unique properties of self-renewal, differentiation, and unspecialization. One of the uses of stem cells in medicine include, bone marrow transplants, which require hematopoietic stem cells, that have been used for many years to treat blood disorders and cancers and replenish damaged cells.

Some of the uses of stem cells in research are helping to find cures, effective treatments, and repair and replace damaged tissues. Stem cell therapy is a strategy that introduces new adult stem cells into damaged tissue in order to treat both, disease and injury.

The bone marrow transplant is a procedure to help replace destroyed or damaged bone marrow with healthy bone marrow stem cells. Stem cells are cells that are immature in the bone marrow that give rise to all our blood cells. Bone marrow is the fatty tissue inside our bones. Bone marrow can help people who are diabetic become insulin-free with treatment for 5 years after using their own blood in stem cell therapy. I believe that bone marrow transplants can positively effect someone's life. Because maybe the disease they have, can be almost fully cured.

There are three types of bone marrow transplants, autologous, allegenic, and the umbilical chord transplant. A stem cell transplant is done after radiation and chemotherapy is complete. A central venous catheter is a tube that stem cells are delivered through into your bloodstream. The process is like getting a blood transfusion. The stem cells travel into the bone marrow through the blood. No surgery is needed for the transplant.

The side effects of bone marrow transplants are due to a high does of chemotherapy. If you have whole body radiotherapy, you may have extra side effects. When you have just gotten your high dose treatment, all of the side effects are at their worst. You will feel better when your blood count begins to rise. Treatments can often cause infertility, in the longer term. Another side effect is Graft…
