While the traditional methodology requires fresh blood, the new procedure allows cells from frozen blood samples to regress to a similar state to that of embryonic stem cells.

“The procedure that we have developed simplifies the process that enables these cells to be obtained. With the traditional method, the blood is centrifuged with different reagents, capable of separating the blood cells according to their size. Our protocol, on the other hand, does not require the use of reagents. This allows for the reduction of costs, time, and the complexity of procedures to be performed in the laboratory”, explain Viviana Meraviglia and Alessandra Zanon, researchers at EURAC Center for Biomedicine and main authors of the study.
