Researchers at the University of Minnesota’s Center of Cardiovascular Repair have reanimated the heart of a dead rat using a process known as decellularisation.

Literally washing away the dead cells with powerful detergents thus leaving only its empty shell. They then injected it with the heart cells of newborn rats and soaked it with a nutrient-rich solution. Eight days later, the world’s first zombie heart was alive… er undead.

The researchers say their next step will be to reanimate a pig’s heart, which unlike a rat’s is compatible for human transplants. [God help us all when zombie pig-men walk the Earth]
