An Overview Of Stem Cell Replacement

Stem cell replacements, also known as bone marrow transplants, may be done when an individual's bone marrow stops working and does not produce enough healthy cells. A stem cell replacement is a procedure characterized by replacing diseased bone marrow with healthy stem cells. Stem cell replacements may use healthy cells from the patient's own body or from a suitable donor. Keep reading to learn more about this procedure, including the types that may be used, what to expect, its side effects, and what conditions stem cell replacement can help treat.

Stem cells are unique human cells with the ability to differentiate into numerous different types of specialized cells in the body. Every cell in the body starts off as a stem cell. All stem cells can self-renew and differentiate into more specialized cells. Stem cells are classified into types based on where they originate from and what they can and cannot do. Embryonic stem cells come from in inner cells of a human blastocyst that develops three to five days after a sperm fertilizes an egg. Adult stem cells are further specialized than embryonic stem cells. These stem cells have the ability to differentiate into different types of cells within the specific organ or tissue they live in. Induced pluripotent stem cells are cells specially engineered in a laboratory by the conversion of tissue-specific cells into cells that behave similarly to embryonic stem cells. Currently, stem cells are used to treat a variety of bone marrow and blood diseases, immune disorders, and blood cancers. The stem cells used in such treatments are adult somatic stem cells that are able to make all cell types that make up blood.
