Thermoresponsive BrushGel Microcarriers for Efficient Cell Expansion and Enzyme‐Reduced Harvesting

Advanced Healthcare Materials, EarlyView.
Askari et al, report on temperature‐responsive microcarriers to minimize enzyme use and cost in dynamic cultures. Abstract Scaling up cell therapy requires efficient expansion of high‐quality cells. Microcarrier(MC)‐based systems offer high surface‐to‐volume ratios and reduce culture media usage.

High‐Throughput Encapsulation of Stem Cells: Characterizing Dynamic Culture Variability With a Millifluidic Approach

Advanced Healthcare Materials, EarlyView.
A high throughput millifluidic encapsulation platform is engineered and standardized. The system's output allows the monitoring of cell expansion in strong dynamic conditions. High polymer crosslinking leads to higher cell proliferation and lower cell growth on microgel's surface.

Three new LmbU targets outside lmb cluster inhibit lincomycin biosynthesis in Streptomyces lincolnensis

Microbial Cell Factories
Background Antibiotics biosynthesis is usually regulated by the cluster-situated regulatory gene(s) (CSRG(s)), which directly regulate the genes within the corresponding biosynthetic gene cluster (BGC).

Nanobody‐Decorated Lipid Nanoparticles for Enhanced mRNA Delivery to Tumors In Vivo

Advanced Healthcare Materials, EarlyView.
This study presents a targeted mRNA‐LNP platform engineered with anti‐PSMA nanobodies for prostate cancer therapy. Using different in vivo models, the authors demonstrate selective uptake and mRNA delivery in PSMA+ cancer cells. However, while targeting is enhanced, mRNA delivery efficacy is limited by tissue penetration, tumor necrosis, and immune ...

Improved methanol-derived lovastatin production through enhancement of the biosynthetic pathway and intracellular lovastatin efflux in methylotrophic yeast

Bioresources and Bioprocessing, 2018
Background Methanol has attracted interest as a substrate for improvement of product titers and yields of bioprocesses, because methanol has a more reduced state than sugars do and can be renewably synthesized from abundant natural gas supplies.
