Cells capable of becoming tissues of the brain and central nervous system.
Capable of giving rise to most tissues of an organism.
Cells that have the ability to divide for indefinite periods in culture and give rise to specialized cells.
Having unlimited capability. Totipotent cells have the capacity to specialize into extraembryonic membranes and tissues, the embryo, and all postembryonic tissues and organs.
The process of giving tissues or cells to treat a disease. The tissue or cells may come from the same patient (autologous) or from another person (allogenic).
