title: Regenerative medicine for stroke - are we there yet?
abstract: With the development of stem cell (SC) biology, cell-based therapy has become a highly challenging field for experimental and clinical research. Among neurological disorders, stroke has pioneered the clinical application of SC. Safety concerns have prevailed for pilot clinical studies and important preclinical work is ongoing to help SC therapy reach the level of generalization. Stroke is classically divided into an acute, a subacute and a chronic phase. Each phase is defined by a complex array of events with overlapping and distinct kinetics that lead to both rapid tissue degeneration and long-lasting remodeling. Each SC type possesses intrinsic properties - transposed via cell-autonomous and non-cell-autonomous signaling - that would more specifically address some of these events. A better definition of what is expected from SC therapy in stroke might help assign SC sources to the acute or chronic phases and possibly optimize their use in the clinic.
