    摘要: PROBLEM TO BE SOLVED: To provide a bone tissue regeneration sheet having a cortical bone tissue layer of 200 μm or more in thickness.
    SOLUTION: This bone tissue regeneration sheet is produced by seeding chondroblast or stem cells for differentiating to chondrocyte on one side of a sheet-like porous body composed of bioabsorbable synthetic polymer, taking the seeded porous body into a culture medium, applying acceleration of 100 to 1000 G to the culture medium for a predetermined time so as to aggregate the chondroblast or the stem cells for differentiating to chondrocyte, culturing the aggregated cells in a culture medium not containing serum but containing one or two or more kinds selected from ascorbic acid, an ascorbic acid derivative, and dexamethasone without applying acceleration to form a chondrocyte layer having a thickness of 200 μm or more, and culturing the chondrocyte layer in a culture medium containing serum and endochondrally ossifying it to form the cortical bone tissue layer of 200 μm in thickness.

    摘要: PROBLEM TO BE SOLVED: To provide an additive for in vitro maturation culture which enables the new and efficient in vitro maturation culture of an immature ovum, and a method for in vitro culturing an immature ovum in the presence of the additives.
    SOLUTION: Provided is an additive for in vitro maturation culture of an immature ovum which includes at least either one of secreted materials of cells derived from amniotic membrane or solubilized amniotic components. A mature ovum can be efficiently produced by culturing an immature ovum in the coexistence with the additives.
