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
Human germline engineering by their pseudonyms, Lulu () and Nana (). Human germline engineering Human germline engineering is the process by which the genome of an individual is edited in such a way that the change is heritable. This is achieved through genetic alterations within the germinal cells, or the reproductive cells, such as the oocyte and spermatogonium. Human germline engineering should not be confused with gene therapy. Gene therapy consists of altering somatic cells, which are all cells in the body that are not involved in reproduction. While gene therapy does change the genome of the targeted cells, these cells are not
