小中大Enzyme dissociation protocol for epidermal stem cells:
Adherent cells were then harvested, with 0.25% dispase II (for 3minutes) and then one or two subsequent treatments with trypsin-EDTA
(0.3% trypsin and 1% EDTA) at 37°C, gently pipetted to help dislodge thecells, with rapid trypsin neutralization to prevent cell damage,
isolated into a single-cell suspension
