Epilepsy is a prevalent pathology. A significative number of patients do not achieve an adequate response to pharmacological therapy. This observation has motivated the search for new strategies. The now well known concept of neurogenesis in the adult brain, in particular in the subventricular and dentate gyrus subgranular zones, has encouraged the development of strategies that might control this mechanism in order to obtain either antiepileptogenic or repair effects. Most studies focus on the transplantation of neural progenitor or fetal cells in experimental models, although bone marrow stem cell therapy is promising. In neurological diseases in which damage is frequently irreversible, regenerative strategies could represent a new path towards better treatment options. In our laboratory, we have been studying the therapeutic potential of bone marrow stem cells in controlling recurrent spontaneous seizures associated to the pilocarpine model of epilepsy with excellent results. We are also running the first study using bone marrow stem cell transplantation in the treatment of epilepsy in humans.
