Journal ArticleDOI
Oxygen tension influences the differentiation, maturation and apoptosis of human megakaryocytes
TL;DR: In this paper, the authors investigated whether pO2 influences the maturation of megakaryocytes (Mks) adjacent to bone marrow sinus walls and subsequently release platelets within the sinusoidal space or in lung capillaries.
Journal ArticleDOI
Strategies for Improved dCO2 Removal in Large-Scale Fed-Batch Cultures
TL;DR: The authors proposed a comprehensive approach to maintain dCO2 levels between 40 and 120 mmHg throughout the 14‐day fed‐batch process and found that the benefit of a lower level of sodium bicarbonate in the culture medium was transient for batch and fed-batch cultures.
Journal ArticleDOI
High-throughput miniaturized bioreactors for cell culture process development: Reproducibility, scalability, and control
TL;DR: The utility of the ambr™ system as a high throughput system for cell culture process development is demonstrated and changes to important process parameters in ambr resulted in predictable cell growth, viability and titer changes, which were in good agreement to data from the conventional larger scale bioreactors.
Journal ArticleDOI
Oxygen tension modulates the expression of cytokine receptors, transcription factors, and lineage-specific markers in cultured human megakaryocytes.
TL;DR: These findings demonstrate that cytokine receptors c-Mpl and IL-3R, and Mk differentiation-specific surface receptors CD41a, CD42a, and NMDAR1, are significantly modulated by pO2, and suggest that one of the mechanisms of enhanced maturation at 20% O2 may involve regulation of transcription factors GATA-1 and NF-E2.
Journal ArticleDOI
Multimodal chromatography: Characterization of protein binding and selectivity enhancement through mobile phase modulators.
TL;DR: Improved fundamental understanding of protein binding to stationary phases to enable the development of efficient and robust purification processes was applied towards screening mobile phase modulators that could selectively decrease host cell protein levels during monoclonal antibody purification.
