Abstract: The present disclosure relates to a method for producing mesenchymal stem cells from pluripotent stem cells and mesenchymal stem cells prepared by the method. The present disclosure enables mesenchymal stem cells having superior proliferation rate while having superior intrinsic biological activity to be obtained with high yield by sequentially performing three-dimensional suspension culture using pluripotent stem cells, particularly induced pluripotent stem cells (iPSCs), as starting cells and adherent culture of cell aggregates formed therethrough. The mesenchymal stem cells produced by the method of the present disclosure can be usefully used in compositions for treating bone diseases, cartilage diseases or inflammatory and autoimmune diseases owing to high differentiation efficiency into bone and cartilage and superior anti-inflammatory activity.

Abstract: Disclosed herein is an air curtain system including a plant cultivation device for air purification. The air curtain system includes: an air purification wall part forming a vertical body of the air curtain system and having a sidewall on which plants are planted, the air purification wall part drawing in air and filtering out pollutants including fine dust and ultrafine dust from the drawn-in air; an air curtain injection part forming a roof of the air curtain system and having an air discharge port formed along a periphery of the roof, the air curtain injection part receiving the air filtered through the air purification wall part and discharging the received air vertically downwards through the air discharge port; and an air suction part forming a floor of the air curtain system and having an air suction port formed along a periphery of the floor, the air suction part suctioning the air discharged through the air discharge port of the air curtain injection part.
