Developmental Biology Collection of Serum- and Feeder-free Mouse Embryonic Stem Cell-conditioned Medium for a Cell-free Approach Yun-Ui Bae1, Hoon-Ki Sung2,3, Jae-Ryong Kim1 1Department of Biochemistry and Molecular Biology and Smart-aging Convergence Research Center, College of Medicine, Yeungnam University, 2Physiology and Experimental Medicine Program, The Hospital for Sick Children Research Institute, 3Department of Laboratory Medicine and Pathobiology, University of Toronto This protocol provides a method for the collection of mouse embryonic stem cell (mESC)-conditioned medium (mESC-CM) derived from serum (fetal bovine serum, FBS)- and feeder (mouse embryonic fibroblasts, MEFs)-free conditions for a cell-free approach. It may be applicable for the treatment of aging and aging-associated diseases.
