  • Patent number: 11925726
    Abstract: The present disclosure is related to a perfusable-type bio-dual proximal tubule cell construct and a producing method thereof capable of applying an in vitro artificial organ model configured to include a first bioink comprising a decellularized substance derived from a mammalian kidney tissue and human umbilical vascular endothelial cells (HUVECs) and a second bioink comprising the decellularized substance and renal proximal tubular epithelial cells (RPTECs), wherein the first bioink and the second bioink are coaxial and printed in tubular constructs having different inner diameters. According to the present disclosure, it is possible to use the renal proximal tubule-on-a-chip as a bioreactor capable of observing a biological drug reaction similar to a real drug by perfusing various drugs to the renal proximal tubule-on-a-chip.

  • Patent number: 7451976
    Abstract: A media pickup apparatus includes a push plate for pushing media stored in a cassette body towards a discharge port of the cassette body. A driving source provides power to the push plate so as to allow the push plate to push the media towards the discharge port of the cassette body. A pickup roller is rotatably coupled to one side of a roller bracket and biased towards the push plate by means of an elastic member in such a manner that the pickup roller elastically makes contact with the media pushed by the push plate, in order to discharge the media from a media cassette by separating the media sheet by sheet. A sensor detects a position of the pickup roller so as to provide data for operating the driving source. The media make contact with the pickup roller with a substantially constant contact force so that media are reliably discharged from the media cassette sheet by sheet.
