  • Publication number: 20180243476
    Abstract: Provided is a cell sheet suitable for cartilage repair. The present invention provides a cell sheet for cartilage repair, formed from a culture of cells derived from a cartilage tissue, and the cell sheet is negative for immunostaining using an antibody against type II collagen. The present invention also provides a method for producing a cell sheet for cartilage repair, formed from a culture of cells derived from a cartilage tissue, and the method includes culturing cells derived from a cartilage tissue on a surface of a membrane, where a temperature-responsive polymer is immobilized on the surface, to give the cell sheet. The culturing is stopped before the cell sheet becomes positive for immunostaining using an antibody against type II collagen.

  • Patent number: 9363196
    Abstract: The present invention is provided with: a data-driven processor comprising at least a firing control which determines whether or not firing conditions have been met by determining whether or not all packets necessary for instruction execution have been received when a packet that convey a part of partitioned data to be processed has been input, and a data processing unit for performing processing corresponding to the packets transmitted from the firing control if the firing conditions have been met; a power supply circuit for supplying power to the data-driven processor; and overload avoidance means for refusing input of the packets to the data-driven processor, if a determination has been made that a data processing load in the data-driven processor may reach an overloaded state in which the data processing may stall, on the basis of current consumption in the data-driven processor. Accordingly, power consumption in a networking system is reduced.
