Oct 29, 2018 · Adult stem cells that have been altered to what appear to be pluripotent cells need to be tested in comparison with human embryonic cells, researchers say, to determine whether they do, indeed, have the same pluripotent qualities.
Adult stem cells, similar to embryonic stem cells, have the ability to differentiate into more than one cell type, but unlike embryonic stem cells they are often restricted to certain lineages.
4) From other adult stem cells: A number of research groups have reported that certain kinds of adult stem cells can transform, or differentiate, into apparently unrelated cell types (such as brain stem cells that differentiate into blood cells or blood-forming cells that differentiate into cardiac muscle cells).

The adult stem cell can renew itself and can differentiate to yield some or all of the major specialized cell types of the tissue or organ. The primary roles of adult stem cells in a living organism are to maintain and repair the tissue in which they are found.
Although research into adult stem cells is promising, adult stem cells may not be as versatile and durable as are embryonic stem cells. Adult stem cells may not be able to be manipulated to produce all cell types, which limits how adult stem cells can be used to treat diseases.
Adult stem cells are the body’s toolbox, called into action by normal wear and tear on the body, and when serious damage or disease attack. Researchers believe that adult stem cells also have the potential, as yet untapped, to be tools in medicine.

The human ASC signa-ture provided prognostic information and was associated with genomic alterations that inﬂuence cancer aggressiveness and lineage differentiation. In this analysis, we simpliﬁed the nomen-
When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell. Stem cells are distinguished from other cell types by two important characteristics.
