METHOD OF PREPARING MESENCHYMAL-LIKE STEM CELLS AND MESENCHYMAL-LIKE STEM CELLS PREPARED THEREBY

摘要

Disclosed is a method for effectively preparing mesenchymal-like stem cells, the method including: preparing human pluripotent stem cells cultured to passage 70 or lower after establishment of cell lines; inducing differentiation of the human pluripotent stem cells to produce embryoid bodies and selecting cystic embryoid bodies therefrom; loading the cystic embryoid bodies on a cell-permeable three-dimensional (3D) culture unit to isolate mesenchymal-like stem cells therefrom; isolating only monolayer-shaped cell clusters from the mesenchymal-like stem cells passing through the cell-permeable 3D culture unit; and uniformizing sizes of the monolayer-shaped cell clusters, in which the mesenchymal-like stem cells have anti-inflammatory efficacy and immunosuppression. Further, disclosed are mesenchymal-like stem cells prepared by the preparation method, a transporter or a therapeutic composition including the mesenchymal-like stem cells, and a composition for prevention or treatment of diseases that includes an active ingredient or exosomes secreted from the mesenchymal-like stem cells.
