Adult Stem Cell Plasticity Defined
Introduction Investigators have postulated since the turn of the century that some cells in the body appear to participate in the formation of new cells to replace injured, aged, or infected cells in tissues and organs. The concept that certain specialized cells within an organ (stem cells) could give rise to mature functioning cells in that same organ has been demonstrated most clearly in the ...
متن کاملAdult stem cell plasticity: fact or artifact?
There has been unprecedented recent interest in stem cells, mainly because of the hope they offer for cell therapy. Adult stem cells are an attractive source of cells for therapy, especially in view of the recent claims that they are remarkably plastic in their developmental potential when exposed to new environments. Some of these claims have been either difficult to reproduce or shown to be m...
متن کاملEvaluation of neural plasticity in adult stem cells.
The role of stem cells has long been known in reproductive organs and various tissues including the haematopoietic system and skin. During the last decade, stem cells have also been identified in other organs, including the nervous system, both during development and in post-natal life. More recently, evidence has been presented that stem cells thought to be responsible for the generation of ma...
متن کاملSTEM CELL Stem cell plasticity
The quintessential stem cell is the embryonal stem (ES) cell which has unlimited self-renewal and multipotent differentiation potential. Stem cells have also been identified in most tissues. Compared with ES cells, tissue specific stem cells have less self-renewal ability and, although they differentiate into multiple lineages, they are not multipotent. A large number of recent published studie...
متن کاملEphB signaling controls lineage plasticity of adult neural stem cell niche cells.
Stem cells remain in specialized niches over the lifespan of the organism in many organs to ensure tissue homeostasis and enable regeneration. How the niche is maintained is not understood, but is probably as important as intrinsic stem cell self-renewal capacity for tissue integrity. We here demonstrate a high degree of phenotypic plasticity of the two main niche cell types, ependymal cells an...
