Worldwide, tissue engineering and cellular replacement therapies are at the forefront of the regenerative medicine agenda, and researchers are addressing key diseases, including diabetes, stroke and neurological disorders. It is becoming evident that neurological cell therapy is a necessarily complex endeavor. The brain as a cellular environment is complex, with diverse cell populations, including specialized neurons (e.g., dopaminergic, motor and glutamatergic neurons), each with specific functions. The population also contains glial cells (astrocytes and oligodendrocytes) that offer the supportive network for neuronal function. Neurological disorders have wide and varied pathologies; they can affect predominantly one cell type or a multitude of cell types, which is the case for ischemic stroke. Both neuronal and glial cells are affected by stroke and, depending on the region of the brain affected, different specialized cells are influenced. This review will address currently available therapies and focus on the application and potential of cell replacement, including stem cells and immortalized cell line-derived neurons as regenerative therapies for ischemic stroke, addressing current advances and challenges ahead.
