Scientists at the University of Nottingham are developing a liquid bone tissue containing stem cells that may generate new bone growth in patients with osteoporosis. The paste would be injected into problem areas in hopes of regenerating weak and fragile bones. Since stem cells often die after being transplanted, the research team is attempting to avoid this problem by protecting the stem cells with calcium phosphate. Although the paste has not yet reached clinical trials, the scientists behind the paste hope to create a treatment that would strengthen bones before fracturing, avoiding high health care costs associated with such injuries.
