Adult stem cells are the successful standard for stem cells. Although in the past their regenerative/reparative capacity was ignored, misunderstood, or even maligned, a rapidly growing host of clinical applications are being developed, and the clinical utility of adult stem cells is increasingly validated in the thumbed.xyz by: 7. Human mesenchymal stem cells are thought to be multipotent cells, which are present in adult marrow, that can replicate as undifferentiated cells and that have the potential to differentiate to lineages of mesenchymal tissues, including bone, cartilage, fat, Cited by:

Here, we demonstrate the generation of iPS cells from adult human dermal fibroblasts with the same four factors: Oct3/4, Sox2, Klf4, and c-Myc. Human iPS cells were similar to human embryonic stem (ES) cells in morphology, proliferation, surface antigens, gene expression, epigenetic status of pluripotent cell-specific genes, and telomerase activity. Jun 17,  · Adult stem cells are rare. Their primary functions are to maintain the steady state functioning of a cell—called homeostasis—and, with limitations, to replace cells that die because of injury or disease [ 44, 58 ].

Human adult stem cells are being evaluated widely for various therapeutic approaches. Several recent clinical trials have reported their safety, showing them to be highly resistant to transformation. The clear similarities between stem cell and cancer stem cell genetic programs are nonetheless the basis of a recent proposal that some cancer stem cells could derive from human adult stem . The primary role of adult stem cells in humans is to maintain and repair the tissue in which they are found. While we call them adult stem cells, they are more accurately called somatic (from the Greek word soma = body) because they come virtually any body tissue, not only in adults but children and babies as well. What are Stem Cells?

Adult stem cell Adult stem cells are undifferentiated cells found throughout the body that divide to replenish dying cells and regenerate damaged tissues. Also known as . Jun 08,  · Adult stem cells. These stem cells are found in small numbers in most adult tissues, such as bone marrow or fat. Compared with embryonic stem cells, adult stem cells have a more limited ability to give rise to various cells of the body. Until recently, researchers thought adult stem cells could create only similar types of cells.
