Stem cells are the “building blocks” of the body; they are self-renewing undifferentiated cells that give rise to the specialized cells of the tissues. In adult, stem cells are multipotent, they contribute to homeostasis of the tissues and regeneration after injury. Until recently, it was believed that the adult brain was devoid of stem cells, hence unable to make new neurons and regenerate. The recent confirmation that neurogenesis occurs in the adult brain and neural stem cells (NSCs) reside in the adult central nervous system (CNS) suggests that the adult brain has the potential to regenerate and may be amenable to repair. The advent of adult neurogenesis and NSC research will redefine our understanding of the physio- and pathology of the nervous system, and provide new avenues and opportunities to treat a broad range of neurological diseases, disorders and injuries. Adult NSC-based therapies will involve cellular therapy, but also pharmacology.
