Human mesenchymal stromal cells (hMSCs) hold enormous promise for regenerative medicine. Kansas State University researchers investigated the growth parameters necessary to propagate hMSCs on a larger scale, moving from static cultures to the scope of stirred bioreactor tanks. Now that this group has optimized a new method by which to isolate and expand these hMSCs (please see companion paper by this group), the next challenge was producing enough cells to satisfy future clinical needs. The researchers investigated the growth kinetics and metabolic needs of these cells as the propagation scope increased. The Cellometer Auto 2000 recorded cell viability, size, and [...]
