The question not answered by the article is:
- What did the scientists do with the hearts after they started beating on their own?

(Other three are answered: they decellularized the hearts to make frames and then reseeded those frames with a mixture of living cells from infant rats; they put the frames in a bioreactor and pumped nutrient-rich fluid through to mimic blood flow; they injected/seeded the mixture of newborn rat heart cells into the frames.)
