Bone implant research. Confocal light micrograph of human bone showing the protein osteocalcin (green). This cultured tissue is being used to develop liquid bone implants, enriched with living bone cells, which will form strong tissue when injected into patients with complex fractures and those suffering from osteoporosis (brittle bones). The cells are growing on a glass-foam, a bio- active scaffolding to which they adhere, grow and bind together, resulting in the rapid formation of new tissue. In confocal microscopy a laser excites fluorescent dyes. Photographed at the Imperial College Centre for Tissue Engineering, London. Magnification unknown.
