Stem cells can be divided into two groups, embryonic and adult. Both types share the ability to self-renew and to differentiate into specialized cell types, but they differ in other attributes. Embryonic stem cells are derived during early development at the blastocyst stage and are pluripotent,...
stem cellsepigeneticsDNA methylationchromatinEmbryonic stem (ES) cells are pluripotent cells that differentiate into all cell types of the organism. In adult, multipotent tissue-specific stem cells undergo multi-lineage differentiation to preserve normal tissue homeostasis and repair potential injuries. The...

Dr. Catherine M. Verfaillie and other researchers at theStemCell Institute, University of Minnesota, have discovered a way to coax an adult cell found in the bone marrow to exhibit many of the attributes that supposedly makeembryonic stem cellsirreplaceable to the development future "miracle" medi...
Adult stem cells maintain tissue homeostasis by their ability to both self-renew and differentiate to distinct cell types. Multiple signaling pathways have been shown to play essential roles as extrinsic cues in maintaining adult stem cell identity and a
The hair follicle bulge possesses putative epithelial stem cells. Characterization of these cells has been hampered by the inability to target bulge cells genetically. Here, we use a Keratin1-15 (Krt1-15, also known as K15) promoter to target mouse bulge
Quiescent neural stem cells (NSCs) in the adult mouse brain are the source of neurogenesis that regulates innate and adaptive behaviors. Adult NSCs in the subventricular zone are derived from a subpopulation of embryonic neural stem-progenitor cells (NPCs) that is characterized by a slower cell cy...
The identification of multipotential mesenchymal stem cells (MSCs) derived from adult human tissues, including bone marrow stroma and a number of connective tissues, has provided exciting prospects for cell-based tissue engineering and regeneration. This
Spagnoli said adult stem cells may pose fewer problems than embryonic stem cells, since they are not associated with the ethical controversy that surrounds the latter. Also, they may avoid the problem of rejection by the immune system, since the patient's own cells can be used. ...
