They didn't actually store and revive a heart after ten days. They extrapolated the estimate based on tissue samples taken over the coure of a few hours. To better understand if and how Somah preserved a heart, Thatte and his group harvested two female pig hearts and placed them in two different containers. One was filled with Somah, the other with Celsior from Genzyme – the standard chemical bath which preserves organs in hospitals today. As described in the journal Circulation, the team took tissue samples every four hours from each heart. They found that the Somah heart had a much lower rate of cell decay, including important cardiomyocyte and endothelial cells which are necessary for the heart to work in a new host. Based on this research they concluded that hearts preserved in Somah should be viable for up to 10 days. Celsior can store the organ for 4 hours. That’s an epic difference.
