Elucidation of bone regeneration mechanism

(Tokyo Institute of Technology) Fish have the extraordinary ability to regenerate lost fins and other appendages containing cartilage and bone. The cells responsible for the regeneration offer new clues on how to regenerate tissues in humans. Researchers at Tokyo Institute of Technology (Tokyo Tech) have found a dormant progenitor cell population in zebrafish that regenerates bone cells, or osteoblasts. The study can be read in Developmental Cell.
