| Summary: | Fractures: reprogramming cells to reduce risk in the elderly Reprogramming cells that produce connective tissue to form bone instead could help prevent fractures in the elderly. Bones weaken with age, and fractures are a significant health risk in ageing populations. Most current bone regeneration treatments use stem cells, which can differentiate into any type of cell and have infinite capacity to divide; however, they are difficult to source and can lead to tumor formation. Jongpil Kim at Dongguk University in South Korea and coworkers have reviewed a new method that uses genetic signals to transform connective tissue-forming cells into bone-producing cells. The reprogrammed cells have been shown to generate new bone at the desired site, and because they have already lost their capacity for infinite division, tumor formation risk is greatly reduced. This method shows promise to expand treatment options for fractures and osteoporosis. |
