Differential Phase Contrast Imaging to Predict MSC Immune Function

open access: yesAdvanced Healthcare Materials, EarlyView.
This work employs quantitative differential phase contrast (qDPC) imaging technique to non‐invasively extract morphological features from live Mesenchymal Stromal Cells (MSCs) for single cell prediction on cell immunomodulatory capacity. This work establishes a foundation for scalable, non‐destructive monitoring of MSCs immunomodulatory capacity ...

Impact of Nanoparticle Stiffness on Endosomal Escape and Signaling Pathways in Cytosolic Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
Nanoparticle (NP) stiffness affects cellular uptake, but its impact on intracellular distribution remains unclear. This study synthesizes silica nanocapsules with varying stiffness, inspired by viral mechanisms, and applies assays to measure cellular uptake and escape efficiency.

Engineering Extracellular Microenvironments: The Impact of Fibrous Materials on Cell Behavior

open access: yesAdvanced Healthcare Materials, EarlyView.
Fibrous structures are key elements of the native extracellular matrix and crucial for directing cell behavior. This review discusses how fiber properties such as composition, diameter, and alignment affect cell responses in 2D and 3D systems. Strategies for integrating fibrous cues into engineered tissues are highlighted, and future directions for ...
