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.-

Abstract: An electronic circuit includes first to third transistors. The first transistor has a first channel width and a first channel length and generates a first potential difference by passing an operating current based on a first operating voltage. The second transistor has a second channel width and a second channel length and generates a second potential difference based on the operating current. The third transistor generates a third potential difference based on a second operating voltage and the operating current. A sum of a level of the first operating voltage and a level of the first potential difference corresponds to a sum of a level of the second operating voltage, a level of the second potential difference, and a level of the third potential difference. The first channel width is greater than the second channel width, or the first channel length is longer than the second channel length.

Abstract: The present invention relates to a 3 dimensional mimetic tissue structure—“Assembloid” based on patient-derived multiple cell types to develop next generation organoid technology serving as a novel platform for new drug development and a disease model and a method of manufacturing the same, and more particularly, to a stem cell- or tumor cell-based 3D multicellular mimetic tissue structure manufactured by reconstituting epithelial or tumor cells with various cellular components of a microenvironment such as stromal cells, vascular cells, immune cells or muscle cells based on three-dimensional (3D) bioprinting, and a method of manufacturing the same. As the stem cell- or tumor cell-based 3D multicellular mimetic tissue structure containing the major factors of a tissue microenvironment, such as stromal cells, vascular cells, immune cells and muscle cells, designed according to the present invention is confirmed to mimic physiological and pathological characteristics of tissue in the body better than conventional organoids, normal and tumor assembloids may be used as a new platform for new drug development and a disease model. More specifically, together with 3D bioprinting technology, it is expected that in vitro bladder tissue and bladder tumor tissue are effectively used as a platform to develop precise and personalized therapeutic options for bladder related diseases including bladder cancer.
