  • Method for inducing osteoblast differentiation of human extramedullary adipose tissue cells
    Patent number: 6426222
    Abstract: A method for inducing osteoblast differentiation and/or for obtaining cells engaged in osteoblast differentiation, starting from human extramedullary adipose tissue cells, comprising the step consisting in incubating said starting cells in a liquid nutrient medium for a period of time sufficient to enable said cells to develop, said nutrient medium containing a solution of at least one glucocorticoid and being free from adipogenic factor. Applicable to making bone implants, in particular using autologous cells.
    Type: Grant
    Filed: May 10, 2000
    Date of Patent: July 30, 2002
    Assignee: Bio Holdings International Limited
    Inventors: Jean-Louis Patat, Jean Darondel, Jean-Pierre Ouhayoun, Alain Francis LeCoeur
  • Method of preparing a biological glue able to coagulate simply by addition of calcium ions
    Patent number: 5985315
    Abstract: By placing a blood plasma in contact with a blood coagulation contact phase activator, before or during preparation of a fibrinogen-based biological glue, a preactivated biological glue is obtained which does not coagulate spontaneously but which is capable of coagulating in less than 5 minutes simply by the addition of calcium ions, without the addition of thrombin. The process has application to the field of surgery.

  • Use of a porous calcium carbonate based material as support of a growth factor in the preparation of a bioabsorbable implant
    Patent number: 5711957
    Abstract: A method for treating a living organism includes fitting in the living organism a bioabsorbable implant. The bioabsorbable implant includes a support of porous calcium carbonate based material for supporting at least one growth factor. The calcium carbonate based support material forms an external wall of the support.

  • Use of particles of a biocompatible and bioabsorbable calcium salt as active ingredient in the preparation of a medicinal product intended for the local treatment of bone demineralization diseases
    Patent number: 5618549
    Abstract: A method of treating a living organism having a disease associated with demineralization or mineralization defects of an existing bone by applying in a spongy portion of the bone or in a medullary canal of the bone at least one biocompatible and bioabsorbable calcium salt in the form of particles having dimensions less than 8 mm. The biocompatible and bioabsorbable calcium salt is an active ingredient for reinitiating bone remineralization and reconstruction of resorbed bone spans and increases bone density and bone mass.

  • Use of porous polycrystalline aragonite as a support material for in vitro culture of cells
    Patent number: 5480827
    Abstract: A three-dimensional solid support for the in vitro cultivation of cells consists essentially of porous polycrystalline aragonite in the form of a cylinder, sphere or plate. The support may be used to successively grow layers of different cells on the support, and is particularly useful for cultivating endothelial cells, fibroblasts and bone marrow cells.
