Abstract: The present invention relates to a method of culturing mesenchymal stem cells using gamma-irradiated serum, and more particularly to a method for culturing mesenchymal stem cells, which can improve the adhesion and proliferation rate of stem cells using a medium containing gamma-irradiated serum and an antioxidant. The method for culturing mesenchymal stem cells according to the present invention can restore the adhesion and proliferation rate of stem cells when culturing the stem cells using gamma-irradiated FBS, which is safe from contamination sources but reduces the efficiency of adhesion and proliferation of the cells. Thus, the inventive method is useful for the production of stem cells for cell therapy.

Abstract: Embodiments described herein generally provide for expanding cells in a cell expansion system. The cells may be grown in a bioreactor, and the cells may be activated by an activator (e.g., a soluble activator complex). Nutrient and gas exchange capabilities of a closed, automated cell expansion system may allow cells to be seeded at reduced cell seeding densities, for example. Parameters of the cell growth environment may be manipulated to load the cells into a particular position in the bioreactor for the efficient exchange of nutrients and gases. System parameters may be adjusted to shear any cell colonies that may form during the expansion phase. Metabolic concentrations may be controlled to improve cell growth and viability. Cell residence in the bioreactor may be controlled. In embodiments, the cells may include T cells. In further embodiments, the cells may include T cell subpopulations, including regulatory T cells (Tregs), for example.
