A Practical Gut‐On‐Chip Workflow for Imaging‐Based Assessment of Epithelial Barrier Dynamics During E. coli Co‐Culture

Biotechnology and Bioengineering, EarlyView.
ABSTRACT The intestinal epithelium and its resident microbiota form a dynamic interface that is central to gut homeostasis, but this interface is difficult to model with conventional tools. Static Transwell cultures lack physiological fluid shear, whereas animal models are costly and poorly suited to quantitative, high‐content imaging.

Fouling‐Free Inertial Microfluidic Cell Clarification for Lentivirus Manufacturing

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Lentiviral vectors (LVVs) are widely used as gene‐delivery vehicles in cell and gene therapy, enabling stable integration of transgenes into target cells. However, efficient clarification of LVV harvest remains a major bottleneck in large‐scale manufacturing, as conventional depth filtration often results in significant product loss.

High Cell Density Cultivation of HEK293 Cells Using a 2L Membrane‐Stirred Bioreactor

Biotechnology and Bioengineering, EarlyView.
ABSTRACT The use of perfusion systems for the continuous cultivation of animal cells at high cell density (HCD) for the production of recombinant proteins, viruses, and viral vectors has many advantages. Besides an enhancement of volumetric productivity and high cell viability, the product quality can be improved through a steady‐state environment ...

Eudragit®‐engineered pH‐responsive probiotic microspheres with enhanced gastrointestinal resistance and prolonged storage stability for inflammatory bowel disease therapy

BMEMat, EarlyView.
This study reports the development of AMS@Eud core‐shell microspheres, combining calcium alginate and pH‐responsive Eudragit® L100, which exhibit exceptional gastrointestinal resistance and long‐term storage stability (only 5.28%–9.09% viability loss over 35 days at 4–25°C), and effectively alleviate inflammatory bowel disease via gut microbiota ...

Hyperbranched poly‐L‐lysine surface‐engineered bioprosthetic heart valves with anti‐calcification, anti‐infection, and durability

BMEMat, EarlyView.
The challenges of bioprosthetic heart valves (BHV) with respect to calcification, infection, and poor durability are tackled by surface engineering of hyperbranched poly‐L‐lysine (HBPL), providing a translational solution to improve long‐term valve performance.

Spatio‐Temporal Assessment of Fish Biodiversity in High‐Density Cascade Dam Rivers Using Environmental DNA Metabarcoding

Biological Diversity, EarlyView.
This study employed eDNA technology for biodiversity surveys and conducted high‐density spatiotemporal eDNA sampling to evaluate ecosystem‐scale patterns across temporal, spatial, and habitat dimensions. We identified 97 fish species from 12 orders, 29 families, and 71 genera using eDNA technology. Spatially, fish diversity indices were correlated with

Application of commercial ultrafiltration membranes for protein purification by high performance countercurrent membrane purification (HPCMP)

Biotechnology Progress, EarlyView.
Abstract High performance countercurrent membrane purification (HPCMP) has emerged as a promising diffusive separation strategy for the purification of recombinant proteins and monoclonal antibodies (mAbs). However, prior studies employed dialysis membranes, which are designed for diffusive separations but have not been validated for biopharmaceutical ...
