Sixteen years ago,
scientists Edinburgh graced the front page because the mass media successfully cloned mammal,
Dolly the sheep, at the
Roslin Institute. The birth of lamb is creating hope for a new generation in pengobatan.Kini, the news came back from Edinburgh, precisely in Edinburgh's Centre for
Regenerative Medicine, where scientists continue to develop the technology that was used for Dolly. In a series of experiments, scientists are creating brain tissue of patients with schizophrenia,
bipolar depression, and psychiatric patients lainnya.Dari pieces of skin, the scientists were able to make the neurons are identical to the relevant
brain cells. These brain cells grown in the laboratory so scientists could investigate and uncover the secrets of the patient's neurological condition. "The neurons of a patient can tell us much about the psychological conditions that affect them. But you can not insert a needle into someone's brain and take the cells," Professor Charles ffrench-Constant, director of Edinburgh's Centre for Regenerative Medicine, as quoted from the pages of the Guardian. "But, we have found a way out. We took samples of the patient's skin, then we make the
stem cells. Stem cells are then grown into brain cells. In essence, we change a person's
skin cells into brain cells. In the future, the same can be applied to the liver, heart and other organs that are very difficult to be biopsied. "The experts are concentrating on a number of neurological conditions, including multiple sclerosis, Parkinson's and motor neuron disease. In addition, they also studied schizophrenia and bipolar depression, the two diseases are caused by decreased malfunctions activity otak.Profesor Andrew McIntosh from the
Royal Edinburgh Hospital, who had collaborated in the study, said scientists have difficulty in obtaining the brain samples of patients with schizophrenia, while the patient is still alive. This research makes researchers studied brain cells while the patient is still alive. "We make different types of brain from skin samples of patients with schizophrenia and bipolar depression," said McIntosh. Then, they used a standard psychological medications, such as lithium, to see how these drugs affect the cells in the laboratory. "After that, we also tried a new drug."
