Freed from the prohibition established during the regime of President Bush not to conduct experiments with human embryonic stem cells, now several American and European researchers develop innovative therapeutic experiments performed in animals against various human diseases, which heralds a new era in the history of medicine. One of these therapies try to eliminate cases of Multiple Sclerosis (MS: blurred vision, poor coordination and balance), a disease in which cells of the immune system destroys the myelin (protective covering of nerves that facilitates the transmission of electrical signals) that surrounds nerves of brain and spinal cord, preventing the sending of regular signals from the brain to body nerves. The usual treatment uses immunosupressor drugs to stop damage to myelin and myelin-forming cells. The novelty now is to extract stem cells from the patient, collect, culture and finally inject it into the bloodstream to stop or reverse damage to the nervous system. Some researchers believe that damage can be reversed by activating brain or spinal cord stem cells that will regenerate the myelin sheath. Dr. Paolo Muraro (Imperial College/UK), hopes to cure in this way to 150 to 200 people with MS in London, Edinburgh, USA, Canada and Italy. Later researchers will try to do the same with drugs that will trigger stem cells action.


durante el regimen del presidente Bush para realizar experimentos con células madre embrionarias humanas, ahora varios investigadores americanos y europeos, realizan innovadores experimentos terapéuticos en animales contra diversas enfermedades humanas, lo que augura una nueva era en la historia de la medicina. Una de estas terapias intenta eliminar los casos de Esclerosis Multiple (EM : vision borrosa, pobre coordinacion y balance), enfermedad en la que celulas del sistema immune destruyen la mielina (cubierta protectora de los nervios que facilita la trasmisión de señales eléctricas), que rodea a los nervios cerebrales y de la medula espinal, impidiendo el envio de señales regulares del cerebro a los nervios corporales. El tratamiento usual emplea drogas inmunupresoras para detener el daño a la mielina y a las celulas formadoras de mielina. La novedad actual consiste en extraer celulas madre del propio paciente, colectarlas, multiplicarlas en numero e inyectarlas al torrente sanguíneo, para detener o revertir el daño al sistema nervioso. Algunos investigadores opinan que el daño puede ser revertido activando células madre cerebrales o medulares regeneradoras de la vaina de mielina. El Dr. Muraro (Imperial College/UK), espera tratar de este modo a 150 a 200 personas con EM en Londres, Edinburgo, USA, Canada e Italia. Mas adelante se intentara lograr lo mismo solo con medicamentos activadores de las células madre.
