Abstract: The present invention relates to a medium composition containing an Ecklonia cava extract for dedifferentiation an induced pluripotent stem cell. Also, the present invention relates to a method for differentiating an induced pluripotent stem cell produced by using the medium composition into hepatocytes. When using the medium composition according to the present invention, induced pluripotent stem cells using mesenchymal stem cells can be produced efficiently, and the pluripotent stem cells which have been produced can be useful as a cell treatment agent by being capable of being differentiated into hepatocytes.

When using the medium composition according to the present invention, induced pluripotent stem cells using mesenchymal stem cells can be produced efficiently, and the pluripotent stem cells which have been produced can be useful as a cell treatment agent by being capable of being differentiated into osteoblasts.

Abstract: The present invention relates to a medium composition containing an Ecklonia cava extract for dedifferentiating an induced pluripotent stem cell. Also, the present invention relates to a method for differentiating an induced pluripotent stem cell, produced by using the medium composition into a chondrocyte. When using the medium composition according to the present invention, induced pluripotent stem cells using mesenchymal stem cells can be produced efficiently, and the pluripotent stem cells which have been produced can be useful as a cell treatment agent by being capable of being differentiated into chondrocytes.

Abstract: A mat structure for a vehicle, in which an edging member capable of preventing impurities such as soil from falling down to an indoor floor of the vehicle is sewed on an upper surface of an edge of a mat, and a sewing device capable of easily sewing the edging member and a magic tape on the mat. The mat prevents impurities remaining on the upper mat from falling down to the indoor floor of the vehicle and contaminating inside the vehicle by using the protrusion portion, and passengers may scrape the impurities off bottoms of the passenger's shoes on the protrusion portion so that the impurities remain on the upper mat. Also, the protrusion portion protects a sewing line of the female magic tape against frictions with the bottoms of the shoes, and prevents the sewing line from being torn off.

Abstract: The present invention relates to a medium composition containing an Ecklonia cava extract for dediffentiating an induced pluripotent stem cell. Also, the present invention relates to a method for producing induced pluripotent stem cells using the medium composition. When using the medium composition, according to the present invention, induced pluripotent stem cells using mesenchymal stem cells can be produced safely, easily, and efficiently, and the pluripotent stem cells which have been produced can be useful as a cell treatment agent by being capable of being differentiated into a variety of cells.

Abstract: Provided is a double doormat including an upper mat and a lower mat, and in detail, to a double doormat in which foreign substances, such as dirt on shoes, are accommodated in a space between an upper mat and a lower mat such that an area around an entrance is clean, a cleaning cycle is extended by making the space where the foreign substances are accommodated big, and the accommodated foreign substances are prevented from contaminating an area around the double doormat by escaping upward from the upper mat due to an impact of dusting the shoes.
