This video demonstrates the isolation procedure of the gingival immune cell network from a mouse model. The enzymatic digestion releases the gingival tissue from the attached teeth and bone, which is further mechanically digested, releasing immune cells from the gingiva. The isolated cells are ready for immunological experiments.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Prepare in Advance Prepare Complete media: RPMI supplemented with 2 mM L-glutamine, 100 units/ml penicillin, 100 ug/ml streptomycin, and 10% FBS. Prepare DNase media: 50 ml of RPMI media supplemented with 7.5 µg DNase (Make fresh, keep on ice at all times). Prepare Collagenase-DNase media: 5 ml …
