Macroporous microcarriers entrap cells in a mesh network allowing growth to high densities and protect them from high shear forces in stirred bioreactor cultures. We report the growth of Chinese hamster ovary (CHO) cells producing either recombinant human beta-interferon (β-IFN) or recombinant human tissue-plasminogen activator (t-PA) in suspension or embedded in macroporous microcarriers (Cytopore...
The addition of the non-ionic surfactant, Pluronic F-68, to serum-free CHO cultures causes multi-functional effects that enhance cell yield in agitated cultures and reduce cell adhesion in stationary cultures. Three independent CHO cell lines were subjected to high liquid shear in assay systems that either included or excluded a liquid–gas interface. In the absence of Pluronic, there was a loss in...
