Stem cells By: Jordan, Audrey, & Jayden

A stem cell is a undifferentiated cell of a multicellular organism that is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cells arise by differentiation.

Leukemia

Stem cells are used to treat diseases and cancers such as leukemia. Leukemia is a cancer of white blood cells or leukocytes. Like some blood cells, leukocytes develop from somatic stem cells. Leukocytes are released in the bloodstream to fight infections

Leukemia results when leukocytes begin to grow and function abnormally, becoming cancerous.

When medicine to target and kill the abnormal cells don't work, Physicians sometimes turn to bone marrow transplants.

In a bone marrow transplant, the patients bone marrow stem cells are replaced with those of a healthy, matching donor.

(1) Leukocytes are first killed by a combination of chemotherapy and radiation.

(2) Sample of donors bone marrow containing healthy stem cells is introduced to the patients bloodstream.

(3) If transplant is successful, the stem cells will migrate into patients bone marrow and begin producing new and healthy leukocytes.

But stem cells are not only used for treating leukemia, it is used to cure and fix numerous things in the body.
