  • METHOD FOR CULTURING MESENCHYMAL STEM CELLS
    Publication number: 20190218517
    Abstract: Disclosed is a method for culturing mesenchymal stem cells, comprising culturing mesenchymal stem cells in a medium containing calcium in a concentration of from 2.1 to 3.8 mM and magnesium in a concentration of from 1.0 to 3.0 mM under a hypoxic condition of 2 to 5% oxygen. The culturing method can increase the population of mesenchymal stem cells even with a small number of passages by improving mesenchymal stem cells in proliferative capacity and viability. In addition, the mesenchymal stem cells prepared by the culturing method are effectively used to treat or improve a pulmonary disease.

  • METHOD FOR CULTURING MESENCHYMAL STEM CELLS ACCORDING TO CELL SIZE
    Publication number: 20160222353
    Abstract: A method for culturing mesenchymal stem cells. The method includes isolating mesenchymal stem cells having a size of 8 ?m or less and culturing the mesenchymal stem cells in a medium containing calcium and magnesium and under a low oxygen condition. The method can significantly improve the proliferative capacity and differentiation potential of the mesenchymal stem cells.

  • Method for Culturing Mesenchymal Stem Cells
    Publication number: 20150284686
    Abstract: Disclosed is a method for culturing mesenchymal stem cells, comprising culturing mesenchymal stem cells in a medium containing calcium in a concentration of from 2.1 to 3.8 mM and magnesium in a concentration of from 1.0 to 3.0 mM under a hypoxic condition of 2 to 5% oxygen. The culturing method can increase the population of mesenchymal stem cells even with a small number of passages by improving mesenchymal stem cells in proliferative capacity and viability. In addition, the mesenchymal stem cells prepared by the culturing method are effectively used not only as a safe cell therapeutic agent due to their lacking immunogenicity, but also as a cartilage regenerating medicine owing to their excellent secretion of cytokines.
