Decidua-derived mesenchymal stem cells (Korea university)

The decidua was mechanically peeled from the placenta, washed several times with phosphate buffered saline (PBS), to remove excess blood, and incubated with type I collagenase for three hours after being cut into small pieces. The mononuclear
cells were then collected by centrifugation. Cell pellets were washed and resuspended in α-minimum essential medium (αMEM), supplemented with  fetal bovine serum (10%), and basic fibroblast growth factor (bFGF, 10 ng/ml ). The cells were seeded into a T75 tissue culture flask. After 3-5 days of culturing, the small digested residues were removed, and the adherent cells were cultured.
