  • Publication number: 20140363884
    Abstract: Disclosed is a cell culture tube, having in opposite end walls two respective eccentric openings which communicate with each other through an inner straight passage formed in the cell culture tube, in which the inner straight passage is tilted at an angle relative to a longitudinal axis of the cell culture tube to allow a culture medium to smoothly flow into and out of the inner passage through the openings. Also, provided is a multiple cell culture system using a plurality of the culture tubes.

  • Patent number: 8481305
    Abstract: The present invention relates to a rotation driving device for cell culturing, comprising: a power supplying unit operated by receiving an electric power from an outside; a rotational part rotated by the power supplying unit; and a driving part which is provided at an upper side of the rotational part and maintained in a stopped state during the rotation of the rotational part, and of which an inclination is changed according to a rotational direction of the rotational part. According to the present invention, there is provided a rotation driving device a rotation driving device which enables cells to be uniformly grown by equally distributing a culture solution with help of inclination control, of which a rotational speed is also controlled and which has a firm structure with a strong durability.

  • Publication number: 20120121545
    Abstract: Disclosed is a pharmaceutical composition for treating bone disease or countering inflammation containing cartilage stem cells as an active ingredient. The present disclosure provides a novel cell treatment regimen for bone disease and inflammatory disease using the cartilage stem cells as an active ingredient. When the cartilage stem cells of the present disclosure are administered into the articular capsule, the administered cartilage stem cells are highly effective in treating bone disease and inflammatory bone disease since they grow or differentiate into chondrocytes and exhibit an anti-inflammatory activity. Since the cartilage stem cells of the present disclosure do not express histocompatibility antigens which give rise to rejection in tissue or organ transplants, autologous cells or exogenous cells can be used during cell transplantation for treatment of bone disease and inflammation.

  • Publication number: 20100304473
    Abstract: The present invention relates to a cell culture flask for culturing a cell using a culture solution, particularly to a cell culture flask enabling to culture a cell without any contamination, to automatically introduce and discharge the culture solution or gases and to be stacked in turn, and a cell culture device having the same. The present invention provides a cell culture flask comprising a culture space with a predetermined area for culturing the cell; one or more culture solution inlet ports for introducing the culture solution or the cell into the culture space; one or more culture solution outlet ports for discharging the culture solution or the cell supplied to the culture space; and one or more gas inlet ports for introducing the various gases into the culture space, wherein the cell culture flask is made airtight and formed of a transparent material so that a user can see an internal portion of the cell culture flask, and a cell culture device having the same.
