Molecular Mechanisms of Extracellular Vesicle Biogenesis and Their Impact on the Design of Custom EVs

Advanced Healthcare Materials, EarlyView.
Extracellular vesicles (EVs) are pivotal mediators of intercellular communication and disease, yet the fundamental mechanisms controlling their biogenesis and cargo selection remain unclear. This limitation hinders their diagnostic utility and therapeutic development.

On the weakly competitive case in a two-species chemotaxis model

, 2016
In this article we investigate a parabolic-parabolic-elliptic two-species chemotaxis system with weak competition and show global asymptotic stability of the coexistence steady state under a smallness condition on the chemotactic strengths, which seems ...

Chemotaxis in reverse [PDF]

The Journal of Cell Biology, 2007
A cell polarity switch controls whether cells rush toward an attractive chemical or shift into reverse when they encounter something repulsive, according to Keizer-Gunnink et al. on page 579. They show that the status of phospholipase C (PLC) sets up the polarity axis for directional movement.

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

Advanced 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 ...

Mesoporous Bioactive Glasses: A Powerful Tool in Tissue Engineering and Drug Delivery

Advanced Healthcare Materials, EarlyView.
This work is a comprehensive revision of bioactive glasses (BGs), pioneered by Prof. L.L. Hench, which are key in bone repair and regenerative medicine. Sol–gel methods and mesoporous designs enhanced their bioactivity, ions, and drug delivery. BGs now support gene therapy and 3D‐printed scaffolds, enabling personalized, multifunctional treatments in ...

Engineering CRISPR System‐Based Bacterial Outer Membrane Vesicle Potentiates T Cell Immunity for Enhanced Cancer Immunotherapy

Advanced Materials, EarlyView.
This study develops a multifunctional CRISPR‐dCas9‐based OMV platform termed OMV‐C9I12, which facilitates the coexpression of CXCL9 and IL‐12 within tumor cells. This platform enhances T cell recruitment and activation, synergizes with anti‐PD‐1/PD‐L1 immunotherapy, and amplifies antitumor T cell immunity.

Biomimetic Cell Membrane‐Coated Scaffolds for Enhanced Tissue Regeneration

Advanced Materials, EarlyView.
This review examines the development and use of cell membrane‐coated scaffolds in tissue engineering. Bioinspired phospholipid and glycocalyx coatings enhance anti‐fouling, anti‐thrombogenic, and selective molecular recognition properties. Native cell membrane coatings further support cell‐specific interactions, immune modulation, and reduced bacterial

Advancements in Dissolving Microneedles for Effective Transdermal Delivery in Rheumatoid Arthritis Treatment

Advanced Materials Interfaces, EarlyView.
Rheumatoid arthritis, a chronic inflammatory joint disease, faces limitations with conventional therapies. Dissolving microneedles (DMNs) enable biocompatible, high‐capacity transdermal drug delivery. However, skin elasticity challenges their strength, limiting drug release depth.

An Injection‐Molded Modified Silicone Rubber for Cancer‐on‐Chip Applications

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This study describes the characterization and application of an injection‐molded functionalized PDMS fluidic insert for the commercially available Micronit system. Modified PDMS can accommodate cell culture and is able to covalently bind proteins for long‐lasting coatings under flow‐conditions.
