Adult Stem CellsBy: Emily Bateman
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.
Their Uses In Medicine

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 TransplantsIn 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 DonorAutologous-the donor is also infected personSynegenic-the donor is a twin sibling of the
infected personAllogeneic-the donor is no related/not closely
related to the infected personCordbold-the donor is an umbilical cord
Step 2: Extract the Adult Stem Cells (They’re In the Blood) From The DonorThe 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.
