Describe the process used for harvesting adult stem cells

Stem cell is taken either from bone marrow or from the blood directly

Explanation:

Stem cells are derived from two locations primarily a) Bone Marrow and b) Blood

The first step in this process is to remove the stem cell from its parent location and it is done in the following ways –  

A)For deriving stem cell from blood – A drug with growth factor s is injected. Here no anesthesia is given to the patient. The growth factors leads to the movement of stem cells from bone marrow into the bloods. Blood with stem cells is taken out from the veins and filtered through the apheresis machine.  

B)From Bone marrow – Bone marrow is removed from the pelvic bone through a needle and prepared for transplantation.
