Radial glial cell and OPCs can be generated from radial glial cells "in vitro", more evidence is yet needed to conclude whether this process also occurs in the developing brain. Recently, radial glia that exclusively generate upper-layer cortical neurons have also been discovered. Since upper cortical layers have expanded greatly in recent evolution, and are associated with higher-level information processing and thinking, radial glia have been implicated as important mediators of brain evolution. The best characterized and first widely accepted function of radial glia is their role as scaffolds for neuronal migration in the cerebral and cerebellar cortexes. This role can be easily
Clinical uses of mesenchymal stem cells Clinical uses of mesenchymal stem cells Adult mesenchymal stem cells (MSCs) are being used by researchers in the fields of regenerative medicine and tissue engineering, to artificially reconstruct human tissue which has been previously damaged. Mesenchymal stem cells have the capacity to become any type of fully developed cell, which can contribute to replacing muscle tissues or internal organs. To help discover the therapeutic uses of these stem cells they are grown in laboratories or by using medication to stimulate new cell growth within the human body. In MSC therapy the cells are extracted from the adult patient’s bone marrow
