Abstract: The present invention relates to a method for inducing differentiation, into chondrocytes, of cord blood mononuclear cell-derived induced pluripotent stem cells. In a case where a chondrogenic pellet produced by the method of the present invention is transplanted into a cartilage damage area in vivo, regeneration of cartilage can be effectively exhibited by differentiated chondrocytes. In such a case, an effective cartilage regeneration capacity can be exhibited as compared with a case where chondrocytes produced by differentiation induction with the addition of a recombinant growth factor are transplanted. Thus, the present invention can be usefully used for tissue engineering therapies.

Abstract: A method for preparing chondrocyte pellets including: (a) culturing human induced pluripotent stem cells so as to form and obtain embryoid bodies; (b) inducing the embryonic bodies obtained in step (a) to become outgrowth cells and isolating same; and (c) culturing the outgrowth cells isolated in step (b) in a pellet form. A pharmaceutical composition including the chondrocyte pellets prepared by the preparation method; or a method for preventing or treating arthritis, including administering the chondrocyte pellets prepared by the method to an arthritis patient. Chondrocyte pellets of the present invention have a remarkably high rate of differentiation into chondrocytes, uniform size, and a homogeneous differentiation degree, and a pharmaceutical composition, including the pellets, has excellent cartilage regeneration effects at the site of cartilage damage, and is in injectable form, which does not require surgery, such that pain is relieved and a continuous arthritis treatment is provided.

Abstract: One embodiment of the present invention provides an apparatus and method for inspecting a template using a simplified Hough transform. An apparatus for inspecting a template using a simplified Hough transform according to an embodiment of the present invention comprises a rotation angle determination unit for determining a rotation angle of the template included in the object by performing a first voting procedure on a input image including an object; and a position determining unit for calculating a voting cumulative values for the blocks included in the input image by performing a second voting procedure on the input image, performing a down sampling at least one of the blocks based on the voting cumulative values, and determining a position of the template by performing a third voting procedure on the down sampled blocks.
