  • Patent number: 10513685
    Abstract: Provided is a method that achieves control of embryoid body size and can induce differentiation in a state where the embryoid body size is controlled, by using a cell culture chamber having a plurality of microchambers formed therein. A culture method for causing differentiation of pluripotent mammalian cells uses a cell culture chamber (10) having a plurality of microchambers (11) formed on a culture surface. The cell culture chamber (10) has a culture surface formed of spaces in which the microchambers (11) have a space structure with a height of 10 ?m to 500 ?m and a bottom area of 100 ?m2 to 1 mm2.

  • Patent number: 10434218
    Abstract: A treatment for bioprosthetic tissue used in implants or for assembled bioprosthetic heart valves to reduce in vivo calcification is disclosed. The method includes preconditioning, pre-stressing, or pre-damaging fixed bioprosthetic tissue in a manner that mimics the damage associated with post-implant use, while, and/or subsequently applying a calcification mitigant such as a capping agent or a linking agent to the damaged tissue. The capping agent suppresses the formation of binding sites in the tissue that are exposed or generated by the damage process (service stress) and otherwise would, upon implant, attract calcium, phosphate, immunogenic factors, or other precursors to calcification. The linking agent will act as an elastic reinforcement or shock-absorbing spring element in the tissue structure at the site of damage from the pre-stressing.
