    摘要: Provided are a composition and a kit, each for culturing natural killer cells, and a method of using the same. According to the composition for culturing natural killer cells according to aspect, and a method of culturing natural killer cells using the same, when natural killer cells are cultured in peripheral blood mononuclear cells, they are cultured in a medium including the composition for culturing natural killer cells, the composition including magnetic particles, of which at least one surface is bound with an activating receptor ligand, an inhibitory receptor ligand, a costimulatory receptor ligand, a cytokine, a cytokine receptor, an immune checkpoint ligand, a blocking antibody, or a combination thereof, thereby proliferating natural killer cells in a large quantity and promoting activation or inhibition of natural killer cells, or expansion of natural killer cells. Accordingly, the natural killer cells cultured using the same may be usefully applied to immune cell therapy products. Further, the magnetic particles may be easily separated from the medium, which is a simple and economical manner. Since the safe magnetic particles are used, they are excellent in terms of clinical safety.

    摘要: The present invention relates to a biomimetic nerve chip for evaluating the efficacy and toxicity of a drug, a method for evaluating the efficacy of a drug on nerve cells through astrocytes by using the biomimetic nerve chip, and a method for evaluating the toxicity of a drug on nerve cells through astrocytes by using the biomimetic nerve chip, the biomimetic nerve chip comprising: an astrocyte supply unit and a nerve cell supply unit for simulating nerve tissue; and a culture solution supply unit for supplying a culture solution to the astrocyte supply unit and the nerve cell supply unit. By using the biomimetic nerve chip for evaluating the efficacy and toxicity of a drug provided in the present invention, it is possible to overcome inaccuracies due to differences between the different species in animal experiments in the study of nerve tissues, and using a combination of astrocytes and nerve cells enables use of the nerve chip as a platform to more accurately evaluate the efficacy and toxicity of a drug under conditions similar to in vivo conditions, and the nerve chip can be applied to studies of microenvironments in nerve tissues and other organ-on-a-chip studies. Therefore, the present invention may be utilized in the development of a human-on-a-chip that can effectively analyze the efficacy and toxicity of a drug.
