Developing Efficient Bioreactor Microcarrier Cell Culture System for Large Scale Production of Mesenchymal Stem Cells (MSCs)

A large-scale production of clinical-grade MSCs and their derived products is essential due to their immense therapeutic potential. Even though 3D bioreactors are cost efficient in scale up, the plastic adherence of MSCs, makes expansion in suspension cultures challenging. A variety of microcarriers (MCs) allow plastic adherent cells to grow on their surface while maintaining cells in suspension within a bioreactor for expansion. However, this leads to loss of cells, particularly during separation of cells from the carriers. To overcome this, we identified “dissolvable microcarriers” such as Corning Synthemax II dissolvable MCs, which removes the filtration step.
