The researchers studied how to freeze and store arteries effectively. They tested a chemical called dimethyl sulfoxide on cow arteries. The highest safe concentration they found was 15%. They found that this concentration helped preserve the arteries well. When tested, the arteries retained about 30-40% of their ability to contract and 80% of their ability to relax compared to untreated arteries. They also saw that around 71% of the cells lining the arteries survived the process with minor changes. This research shows that dimethyl sulfoxide can be used to successfully preserve arteries for medical and research purposes.
