He found that the viability of spheroids formed of stem cells remained above 90 percent even a&er 11 days. Using an analogy to illustrate this phenomenon, he says: ‘Stem cells forming spheroids is like animals entering hibernation in winter. Normally, cells are incubated at 37 degrees Celsius, but when placed on the table, the temperature drops to room temperature, around 25 degrees. At this temperature, spheroidal formation protects the cells via reduction of metabolic rates and conservation of energy.’ !is discovery eliminates the need to freeze cells before long-distance transport. With this new UM-developed technology, called spheropreservation, stem cells which aggregate can be transported at room temperature to almost anywhere in the world for scienti"c research or clinical treatment at a cost of merely several US dollars.
