Can a person have multiple stem cell transplants?
Some doctors recommend that patients with multiple myeloma have 2 autologous transplants, 6 to 12 months apart. This approach is called tandem transplant. Studies show that this may help some patients more than a single transplant. The drawback is that it causes more side effects and as a result can be riskier.
How do they count stem cells?
To count the number of actual stem cells and not just the groups of cells (Colonies), you usually use an enzyme to get them off the surface of the plastic and collect them via a centrifuge (a P0 cell count). You can then re-suspend them and place them on a device for counting cells.

What is the name of the cell that divides to form more cells?
Under the right conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells. These daughter cells either become new stem cells (self-renewal) or become specialized cells (differentiation) with a more specific function, such as blood cells, brain cells, heart muscle cells or bone cells.
What are the different types of stem cells?
There are several main categories: the “pluripotent” stem cells (embryonic stem cells and induced pluripotent stem cells) and nonembryonic or somatic stem cells (commonly called “adult” stem cells). Pluripotent stem cells have the ability to differentiate into all of the cells of the adult body.
