Evaluation of triply periodic minimal surface geometries in 3D‐printed PLA scaffolds for chondrogenic differentiation

Biotechnology Progress, EarlyView.
Abstract Triply periodic minimal surface (TPMS) scaffolds are gaining attention in tissue engineering due to their continuous and interconnected porous architecture. In this study, three TPMS geometries—Gyroid, Diamond, and I‐WP—were fabricated from polylactic acid (PLA) using fused deposition modeling (FDM), with all scaffolds designed to maintain the

Optimizing clarification processes in biopharmaceutical manufacturing through quality by design: Strategies, implications, and future prospects

Biotechnology Progress, EarlyView.
Abstract Biopharmaceutical manufacturing processes in which the product of interest is extracellularly expressed typically employ a clarification step following cell culture or fermentation. During clarification, crude cell culture fluid or fermentation broth is processed to remove insoluble solids, cells, debris, and other particulates, with the ...

Scalable production and biophysical characterization of an enzyme cocktail derived from human red blood cells

Biotechnology Progress, EarlyView.
Abstract Red blood cells (RBCs) play a critical role in oxygen and carbon dioxide transport, which is facilitated by RBC‐encapsulated hemoglobin (Hb) and carbonic anhydrase (CA). In addition, RBCs are constantly exposed to oxidative stress due to the intracellular reactive oxygen species (ROS) generated during Hb auto‐oxidation.

Scale‐up of a monoclonal antibody CHO fed‐batch production in stirred tank bioreactors: Effect of hydrodynamic conditions and feeding regimen

Biotechnology Progress, EarlyView.
Abstract Key hydrodynamic‐related parameters such as volumetric power input (P/V), impeller configuration, aeration strategy, and maximum gas sparge rate, as well as an appropriate feeding strategy, must be carefully selected to improve production yields in bioreactor.

Functional CRISPR‐Cas9 knockout screening of the genetic determinants of human fibroblast migration propensity

Biotechnology Progress, EarlyView.
Abstract Directional cell migration plays a central role in a wide range of physiological and pathological conditions, such as embryonic development or tumor metastasis. Steps involved in cell migration include cell polarization, formation of membrane protrusions at the cell front side and adhesion disassembly at the rear side, and a general ...

Automation of an integrated micro‐scale platform for monoclonal antibody process development by incorporation of a depth filter mimic

Biotechnology Progress, EarlyView.
Integrating non‐chromatographic operations, such as low pH viral inactivation and a depth filtration mimic, into an automated micro‐scale platform enhances productivity while reducing resource and time requirements. By facilitating rapid, data‐rich experimentation, the platform offers a powerful and efficient tool for assessing and optimizing ...

Enhanced deoxyviolacein bioproduction via enzyme condensation with a yeast glycolytic enzyme‐derived peptide tag

Biotechnology Progress, EarlyView.
Fusion of a 27‐amino‐acid peptide tag derived from a glycolytic enzyme enabled artificial assembly formation of the two violacein biosynthetic enzymes, VioE and VioC. This assembly resulted in enhanced biosynthesis of deoxyviolacein. Abstract In microbial production, regulating endogenous and exogenous synthetic pathways is essential.

Dynamic pH profiles drive higher cell‐specific and volumetric productivity

Biotechnology Progress, EarlyView.
Implementation of dyamic pH profiles for increased CHO cell culture productivity. Abstract Mammalian cell cultures in bioreactors rely heavily on critical process parameter control to ensure optimal growth, productivity, and reproducibility to produce recombinant therapeutic proteins. Culture pH has been shown to be a critical parameter that influences

Optimizing sterile filtration of nanoemulsions through proper choice of prefilter properties

Biotechnology Progress, EarlyView.
Abstract Nanoemulsions, with droplet sizes between 20 and 200 nm, have emerged as a promising vaccine adjuvant and drug delivery system, enhancing the solubility of hydrophobic drugs for diverse applications. Sterile filtration of nanoemulsions is particularly challenging due to the similar size between the nanodroplets and the 0.2 μm nominal pore size

Artificial intelligence and machine learning‐assisted digital applications for biopharmaceutical manufacturing

Biotechnology Progress, EarlyView.
Abstract Artificial intelligence and automation are no longer just buzzwords in the biopharmaceutical industry. The manufacturing of a class of biologics, comprising monoclonal antibodies, cell therapies, and gene therapies, is far more complex than that of traditional small molecule drugs.
