They discovered this by measuring the expression of a proteins found exclusively in brownish fat, called uncoupling protein-1. However, even in those regions where many brown excess fat cells are present, they are blended with white excess fat cells. ‘It’s a marbling at the cellular level,’ Cypess stated. ‘We wondered: Wouldn’t it be good if you could grow more brown excess fat? The answer is yes.’ In their new study, the researchers succeeded in growing mature human brown fat cells from preadipocytes, or pre-fat cells, that they acquired from a brand new sample of brown fat taken from the throat of an individual having routine medical procedures. The process took about two weeks in a laboratory dish but most likely occurs more quickly in your body, Cypess said. ‘A few of these preadipocytes may have the choice to be either white or dark brown excess fat,’ he said.Controversial stem cell therapies supplied at Beijing Xishan Institute for Practical and Neuroregeneration Recovery, involve injecting cells from aborted fetuses to treat spinal-cord injury and a number of central nervous program diseases. About 1,500 patients have obtained this treatment, including approximately 1,000 foreigners. MRC authors state this latter stem cell therapy may be the only one discussed in high-influence peer-reviewed educational journals. One research documented a spinal-cord injury patient’s early electric motor and sensory improvement, another found no improvement in seven spinal cord injury patients. Another recent publication found the therapy improved some spinal cord injuries in animals but its performance in humans ‘is not yet established.’ Despite the absence of randomized clinical trial evidence that these stem cell therapies function, an ‘increasingly popular but controversial’ tourism market has grown up around them.
