Stem cells taken from adult human bone marrow have been manipulated by scientists at the Maxine Dunitz Neurosurgical Institute at Cedars-Sinai Medical Center to generate aggregates of cells called spheres that are similar to those derived from neural stem cells of the brain. In addition, the bone marrow-derived stem cells, which could be differentiated into neurons and other cells making up the central nervous system, spread far and wide and behaved like neural stem cells when transplanted into the brain tissue of chicken embryos. Results of the experiments, described in the February 2007 of the Journal of Neuroscience Research, support...

Non Embryonic Stem Cell Treatment Allows Paralysed Brazilian To Walk, Talk Again RIO DE JANEIRO, November 23, 2004 (LifeSiteNews.com) - Brazilian scientists have successfully transplanted adult stem cells into a woman's brain, facilitating her recovery from a brain hemorrhage that left her paralysed and unable to talk. Maria da Graca Pomeceno, 54, had bone marrow stem cells taken from her pelvis and injected into her damaged brain. Local television broadcasts showed her walking up stairs and talking. Hans Fernando Dohmann, director of Rio's Pro-Cardiaco Hospital, said that hers was the first reported successful treatment of this condition, but that trials...

THE immune cells that attack the brains and nerves of people with multiple sclerosis could be turned into a weapon against the disease.This month sees the beginning of a trial of a personalised vaccine for MS, designed to rein in and destroy the renegade white blood cells that attack myelin cells lining the brain and nerves of patients.To make the vaccine, PharmaFrontiers of Woodlands, Texas, takes blood from an MS patient and extracts a sample of these renegade cells. The cells are then multiplied and weakened with radiation before being re-injected into the patient, whose immune system will then recognise...
