Yeah, Michigan State does have both an MD and DO program (a vet school too). From what I've heard come of the first year classes are taught together, but DO classes start earlier (they take anatomy first so their fall has one less class).
UMDNJ has 3 medical schools in its system (along with other graduate schools), all different/on diff campuses but still all UMDNJ:
1. UMDNJ-NJMS (MD in Newark)
2. UMDNJ-RWJMS (MD in Piscataway)
3. UMDNJ-SOM (DO in Stratford)
