Commercial Manufacturers Standardize Closed-System Processing Now
Commercial-scale cell and gene therapy manufacturers have increasingly specified fully closed, automated harvesting systems as standard manufacturing architecture across their production lines, treating contamination control as a defining regulatory requirement rather than a best-practice preference layered onto open processing. Several major manufacturers now require documented closed-system validation rather than accepting generic open-bench processing common across earlier clinical development. Suppliers including Miltenyi Biotec and Cytiva have invested in dedicated closed-system engineering development teams, recognizing that manufacturing contracts increasingly hinge on demonstrated contamination control data rather than traditional throughput metrics alone, across nearly every major therapy platform.
Market Impact: New approvals add 340 manufacturing lines
