Process development of human multipotent stromal cell microcarrier culture using an automated high-throughput microbioreactor
Published 2017“…At both scales, the agitation used during culture was the minimum required for microcarrier suspension, NJS . The use of the ambr15, with its improved control compared to the spinner flask, reduced the coefficient of variation on viable cell density in the serum containing medium from 7.65% to 4.08%, and the switch to serum free further reduced these to 1.06% and 0.54% respectively. …”

Production of erythrocytes from directly isolated or Delta1 Notch ligand expanded CD34 hematopoietic progenitor cells: process characterization, monitoring and implications for man...
Published 2013“…High-resolution characterization of the process would identify production strategies for increased efficiency, monitoring and control. Methods: CD34 cord blood cells or equivalent cells that had been pre-expanded for 7 days with Delta1 Notch ligand were placed in erythroid expansion and differentiation conditions in a micro-scale ambr suspension bioreactor. …”

The productivity limit of manufacturing blood cell therapy in scalable stirred bioreactors
Published 2017“…O2 consumption was low (~5x10(-8) µg/cell.hr) theoretically enabling erythroblast densities in excess of 5x10(8) /ml in commercial bioreactors and sub-10 L/unit production volumes. …”

Agitation conditions for the culture and detachment of hMSCs from microcarriers in multiple bioreactor platforms
Published 2016“…In our recent work in different bioreactors up to 2.5 L in scale, we have successfully cultured hMSCs using the minimum agitator speed required for complete microcarrier suspension, NJS. …”

Application of a simple unstructured kinetic and cost of goods models to support T-cell therapy manufacture
Published 2021“…The models demonstrated that although glucose is a limiting factor in batch supplied medium, a delivery rate of glucose at significantly less than the maximal specific consumption rate (0.05 mg 1 ? …”
