PRODUCTION OF BONE AND NACRE FROM BONE-FORMING CELLS IN THE PRESENCE OF NACRE

摘要

According to the invention the artificial fabrication method for fabricating simultaneously or separately bone and nacre is implemented by the activity of osteonacrigenic factors contained in nacre. The method according to the invention consists in using fragments of nacre or powder of nacre resulting from the test of bivalve aquatic Mollusca Gasteropoda or Cephalopoda in the "in vitro" or "in vivo" presence of bone cells or bone-forming cells or cells susceptible of becoming bone-forming cells, associated to one or a plurality of bone fragments. The method according to the invention may be implemented in molds of various shapes and sizes, whereafter the bone parts thus obtained may be used as grafts in bone surgery and the nacre may be used to produce pearls, jewels or objects.
