Stem cells are found in the adult tissue of humans, and can be used to regenerate and give new life to parts of the body that need healing. They are easily accessible in three different areas of the body:
1. Blood. Stem cells can be extracted from the blood when the blood is taken from the body.
2. Adipose. Adipose, or fat tissues, carry stem cells that can be extracted from the body through liposuction, and then removed from the actual adipose cell tissue.
3. Bone Marrow. The bone marrow is located inside the bones of the body, and so must be extracted through the bone. This is done with a long needle, and often in the hip joint region. A hole is drilled into the bone, the needle is inserted, and the bone marrow is extracted. The stem cells must then be extracted from the marrow.
Once the stem cells are extracted, they can be reinserted into the body into the new areas that need the boost from the stem cells. When they are applied, they are able to quickly regenerate, vastly increasing their numbers. The stem cells then go to work on the damaged tissue, helping the bone to regrow and heal, and doing the same for tissue, muscle and other blood related needs.
Regenerative stem cells are necessary parts of many important and life saving surgeries, such as blood transfusions and bone grafts. The stem cells in bone marrow are what help the bone marrow transplants in cancer patients be successful and require less ongoing watch and care than other types of surgeries. Stem cells are also a necessary part of any organ transplant, and are helpful in regrowing parts of an organ that are missing or needed to be removed. When a transplant is necessary, it is the stem cells that are going to be replicating themselves and aiding in the regrowth and attachment of the new organ. Without the power of the stem cell, transplanted organs would not be able to function in their new environment. A stem cell is one that can regenerate tissue, and so it is necessary in any tissue or bone procedure. Because these cells are able to regenerate other cells in the body, they are crucial for any type of healing, and also for our modern healing technologies, such as chemotherapy for cancer and healing cirrhosis. As medicine and research advances, it may be possible to find and extract stem cells from even more places in the body, and not be limited to just the bone marrow, blood and adipose tissues. If they exist in those places, it is likely that they also exist in other places that may end up being easier to discover and extract. But as the field is today, stem cells are not hard to extract and the industry has gotten to the point where the ones that we know of are sufficient for regrowing damaged tissue and other bone and muscle. This alone has saved countless lives.
