Different Types of Stem Cells
There are three main types of stem cells: somatic stem cells, which exist in various tissues of the body; embryonic stem cells, which are formed during embryonic development; and induced pluripotent stem cells, which are artificially created in a laboratory by “reprogramming” somatic stem cells. According to the U.S. Department of Health and Human Services, National Institutes of Health, “All stem cells—regardless of their source—have three general properties: they are capable of dividing and renewing themselves for long periods; they are unspecialized; and they can give rise to specialized cell types” (“Stem Cell Basics II”). Even though there are similarities, each type of stem cell differs in how many different types of cells they can become, their potential for different types of therapy, and how the immune system could react with them during therapy.
Somatic stem cells (also called adult stem cells) are found in small amounts among many tissues and organs of the body; including the brain, teeth, blood vessels, heart, skin, liver, gut, skeletal muscles, bone marrow, and peripheral blood. The plasticity (how many different types of cells a stem cell can become) of somatic stem cells is less than other types of stem cells. Somatic stem cells are multipotent, which means that they can only differentiate into the types of cells that their origin tissue is comprised of. For example, hematopoietic stem cells can differentiate into all types of…
