This video demonstrates an imaging-based method to visualize transplanted luciferase-expressing beta cells into a non-obese diabetic immunodeficient mouse. The introduction of splenocytes from a diabetic mouse leads to progressive beta cell destruction, visually confirmed by declining luminescence after substrate introduction.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Engineering and maintenance of NIT-1 cell lines Maintain NIT-1 cell lines, which share a genetic background with non-obese diabetic (NOD) mice, and 293FT cells in tissue culture-treated dishes in Dulbecco's Modified Eagle Medium (DMEM) containing 4.5 g/L glucose supplemented with 10% fetal bovine serum and 1% p…
