Abstract: A method of sorting undifferentiated cells is provided. Subpopulations of cells contained in a single line of ES cells can be sorted using cell-surface markers. The sorted undifferentiated cells have ability to produce chimera with high contribution and germ line transmission efficiently. These undifferentiated cells can be used as a valuable vehicle for the production of transgenic animals and also knockout animals.

Abstract: A joint structure for a control cable includes an annular cable-end member provided on an end of the control cable, a columnar sleeve arranged in the annular cable-end member and a pair of bushes of the same configuration. Each bush includes an annular part, a cylindrical part, a pair of claw parts and a pair of cradle parts. In this arrangement, the cylindrical part, which is made of elastic material, is inserted between the sleeve and the cable-end member, while a pair of claw parts are engaged with the cradle parts of the opposing bush. The sleeve is provided on the side face with a circumferential bead, interposed between leading ends of the opposing bushes. Even if any force is exerted between the cable-end member and the sleeve, no deformation is caused in the cylindrical parts because of its inelasticity, while the bead prevents relative displacement.
