Abstract
Cell therapy products represent an exciting new class of medicinal products, which must be parenterally administered. Thus, compliance with parenteral preparation guidelines is required. One requirement for parenteral products is the characterization of particle contaminations. As cell-based products are turbid suspensions, containing particles, the cells, characterization and control of foreign particle impurities remain a challenge. Within this study, we evaluated a flow imaging microscopy method for the detection and characterization of subvisible particle contaminations in cell-based products. We found that flow imaging microscopy is a potential method where subvisible particle contaminations can be differentiated from the cells in cell therapy products.
