Abstract: The present invention relates to providing artificial tendon or ligament tissue having sufficient strength. More specifically, artificial tendon or ligament tissue having sufficient strength is provided by embedding collagen-secreting cells in a gel having strength capable of resisting a tensile load and by culturing the cells while applying a tensile load to the gel to produce artificial tendon or ligament tissue. Cells that steadily express the Mkx gene can be used as the collagen-secreting cells. A fibrin gel containing aprotinin can be used as the gel.

Abstract: A cold water discharge apparatus, for discharging water from an outlet port when feed water is hot and from a cold water discharge port when the feed water is cold, includes a temperature-sensitive first switching valve body and a diaphragm-type second switching valve body. The first switching valve body is configured to open/close a cold water discharge flow channel depending on temperature. The second switching valve body is configured to open a discharge flow channel due to the pressure caused by the flow of hot water through the discharge flow channel. The second switching valve body is configured to close the discharge flow channel due to the pressure caused by the flow of the cold water through the cold water discharge flow channel. The second switching valve body is configured to discharge residual water from the cold water discharge flow channel after stopping water has cooled down.
