Definitions
- the present invention relates to a method for producing natural bone and mother-of-pearl from bone-forming mother-of-pearl cells from the aquatic mollusc test.
- it has never been possible to artificially produce a sufficient quantity of bone tissue of animal or human origin intended to serve as a graft.
- the surgical circumstances that can give rise to the need for bone grafts are numerous: orthopedic surgery, trauma or plastic repair surgery, neurosurgery, carcinology eu; ... Dan ⁇ - all cases, the grafts come from: - either from the patient itself and in this case an autograft is performed - that is, a bone bank made up of bone parts free of their organic part which can cause immune reactions sterilized by ionizing radiation and frozen.
- the production protocols relating to the process according to the invention are as follows: A layer of cells phenotypically and biochemically recognized to be bone-forming cells (osteoblasts) is placed in an appropriate culture medium: -1) Particles of mother-of-pearl or mother-of-pearl powder
- Bone fragments and pearl fragments In a particular situation.
- physiological normal bone formation is observed in several places in the culture and at a distance from the fragments of mother-of-pearl.
- second case a) An increase in volume of the explant by apposition of newly formed bone and formation of bone fragments in the immediate environment of the bone and mother-of-pearl.
- the study by microspectroscopy showed that the mineral deposit of the newly formed mother-of-pearl is very characteristic and specific of this substance.
- the study with the electron microscope, with the photon microscope in polarized light, by immunocytology and radiology has shown that the neo-formed bone is of the same nature as the initial bone fragment with the presence of bone-specific coUagen and mineral
- the method according to the invention has been implemented in animals. Fragments of mother-of-pearl or mother-of-pearl powder were placed according to a specific protocol in the presence of bone cells which form bone or are supposed to be able to do so. In all cases, the formation of newly formed bone with all the characteristics and specificities of physiological bone was observed.
- the methods according to the invention demonstrate:
- the bone-forming cells are derived from bone fragments originating from different groups of vertebrates in particular, from human bone. Mother-of-pearl comes from the pearly test of bivalve, gastropod or cephalopod aquatic molluscs.
- the method according to the invention can be implemented in modules of variable size and shape. These modules will serve as molds in which the method according to the invention will develop in order to obtain replicas of bone or mother-of-pearl.
- the method according to the invention can, on the one hand, lead to the manufacture of bone pieces intended to serve as grafts in bone surgery and, on the other hand, to the production of mother-of-pearl, pearls, jewelry and mother-of-pearl objects, of variable shape and size without this being limiting.
- mother-of-pearl, pearls, jewelry and mother-of-pearl objects of variable shape and size without this being limiting.
