Strategizing Scale-Up and Scale-Out for Cell Therapy Production

When considering strategies for expanding the number of cells being grown to support cell therapy development, companies often focus on decisions regarding scale-up and scale-out: increasing capacity either by using larger vessels to increase production volume or by implementing more units of the same vessel, respectively. Complete workflows often involve both. Figure 1 shows an example of scaling out from one to multiple cell culture flasks of the same dimension before transitioning to a larger format. Scale-out can be straightforward…

A Complete Solution for MSC Therapy Workflows: Cell Scale-Up, Cryopreservation, and DMSO Removal

Mesenchymal stem cells (MSCs) are used frequently for cell therapy applications. As multipotent cells, they can differentiate into other lineages such as adipocytes, osteocytes, and chondrocytes. Additionally, they are known to secrete trophic factors that can play important roles in immunoregulation. Although MSCs can be isolated from several different tissue sources, those derived from bone marrow commonly are studied because they are easy to access in quantities large enough for therapeutic dosing (2 × 106 cells/kg of body weight). Still,…
