What Are They? Adult stem cells (ASC) are undifferentiated cells that are in the body after development.
The Two Main Properties Of ASC Self-renewal-the ability to go through the cycle of cell division many times while still keeping its undifferentiated state Multipotency (Multidifferentiative Potential)-the ability to make offspring of many different cell types.
Where Are They Found? Any where in the body but are mostly extracted from the blood and bone marrow.

The Steps To A Blood (Adult Stem Cell) Transplant For A leukemia Patient
What Is A Transplant? In a bone marrow, or blood transplant for leukemia you are getting rid of all the unusual leukocytes in a patient and are replacing them with the new ones
History Of ASC Transplants In 1968 the first successful bone marrow transplant took place. Bone marrow is transplanted everyday to treat a variety of blood and bone marrow diseases such as blood cancers and immune disorders.
What Is Leukemia? Leukemia is a cancer that affects white blood cells (leukocytes). White blood cells are made by adult stem cells and are released into the blood stream to fight infections. When you have leukemia your white blood cells don’t grow nor function correctly. These cells can no longer fight infections and conflict with functions of other organs.
Step 1: Find A Donor Autologous-the donor is also infected person Synegenic-the donor is a twin sibling of the infected person Allogeneic-the donor is no related/not closely related to the infected person Cordbold-the donor is an umbilical cord
Step 2: Extract the Adult Stem Cells(They’re In the Blood) From The Donor The donor is put on a medication for four to five days before the transplant that stimulates the production of adult stem cells in to the blood stream. Next, the donor must be administered anesthesia while the healthy blood cells are collected.
Step 3:If It Is An Autologous Donation The patient’s blood is put in a freezer (apheresis). After it is cold, it is taken in a machine that confines and kills the leukemia affected cells.
Step 3: If It Is Any Other Donation The Blood is frozen until needed.
Step 4: “Cleaning The Infected Patient” Before the patient receives the unaffected blood he/she goes through en enduring dose of radiation or chemotherapy to clear their body of any affected cells. Also to make sure every last affected cell is killed, doctors will put an additional drug in their blood stream to get the few cells chemo or radiation might have missed. This process is called purging. If the affected cells are not perfectly removed from the patient the chances are very high that they will have a relapse.
Step 5: Healing The Infected Patient After the patient is “clean”, the new blood is given to them.
