Washington: Scientists have successfully developed `artificial bones` from umbilical cord stem cells, paving way for repair of bones and replacement of lost cartilage in limbs. Scientists in Granada, Spain, patented a new bio-material that facilitates generating bone tissue or artificial bones. The material consists of an activated carbon cloth support for cells that differentiate giving rise to a product that can promote bone growth. Although the method has not yet been applied in living organisms, laboratory results are highly promising. In the future, they could help manufacture medicines for the repair of bone or osteochondrial, tumour or traumatic lesions and to replace lost cartilage in limbs, researchers said. After obtaining artificial bones in the laboratory, the researchers` next step is to implant this bio-material in experimental animal models like rats or rabbits to see if it can regenerate bone in them. The scientists have made this important scientific breakthrough after years of research in cell biology, radiobiology and materials studies.
