WHAT ARE ADULT
Adult stem cells are cells which have not completely differentiated. They are found in all tissues of the human body. Adult stem cells, also known as somatic stem cells, have the potential to transform themselves into practically all other cell types. They can also revert to being stem cells with a broader capacity to differentiate.
Sources of Stem Cells
Sources for adult stem cells are either a donor (allogeneic) or the patient (autologous). According to the National Institutes of Health website, "the primary roles of adult stem cells in a living organism are to maintain and repair the tissue in which they are found". An adult stem cell can divide and renew itself. It can differentiate itself to become other types of cells. For these reasons, adult stem cells play an important role in medical research and patient treatments.
