An active matrix substrate is provided with: a plurality of source wiring lines and a plurality of gate wiring lines which are arranged in a matrix; and pixels having thin film transistors disposed in the vicinity of the intersections of the source wiring lines and the gate wiring lines, and pixel electrodes connected to the thin film transistors. The instrument includes an elongate shaft having two ends with a handle at a first end of the shaft, and a grasping tip at a second end of the shaft. The polyurethane foam which constitutes the elastic member can be produced by free foaming. The UE can use the handover identifier which relatively occupies small amount of radio resources during handover or initial access process. Methods of preparing adherent stromal cells and pharmaceutical compositions comprising the cells are also described.
