Morphometric‐Assisted Prediction of Developmental Toxicity Using Stem Cell‐Based Embryo Models in Microwells

open access: yesAdvanced Healthcare Materials, EarlyView.
This proof‐of‐concept study involves high‐throughput teratogenicity screening of compounds using XEn/EpiCs, a 3D stem cell‐based embryo model, within microwells. The term ‘morphotoxicity’ is introduced to complement traditional cytotoxicity assays through automated feature extraction and machine‐learning‐assisted classification of morphologies.

Rational Design of Unsaturated, Thioether Ionizable Lipids for Enhanced In Vivo mRNA Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
Lipid nanoparticles (LNPs) have rapidly become the delivery system of choice for RNA therapeutics. Here, a rational design approach is taken to improve the effectiveness of LNPs based on an ionizable thioether lipid library. The incorporation of unsaturated tails and bulkier, hydrophobic head groups significantly enhances their functionality and ...
