Figure 2:Comparison between culture processes in the Quantum® device and traditional flasks: MSC culture from thawed P2 MSC e×panded from fresh cells (20×10-6 cells/Quantum). After P0 and P1 e×pansion in flasks from fresh BM, cells were frozen. Three bags containing frozen P2 MSC from flasks from the same donor were thawed and cells were seeded in parallel in flasks (80×10E-6 MSC) or Quantum® devices (20×10-6 MSC). Results were also compared with those previously obtained after P2 from fresh cells from the same donor.
