Unraveling the Heterogeneity of Cargo Distribution in the Exogenous Association of Proteins With Extracellular Vesicles

open access: yesAdvanced Healthcare Materials, EarlyView.
We characterized the distribution of cargo proteins associated with extracellular vesicles using various exogenous loading methods. In all cases, single‐particle analysis revealed that the distribution of protein content per EV is heterogeneous, following an exponential decay function.

Membrane Vesicles from Lacticaseibacillus Casei BL23 Exhibit Antimicrobial Activity Against Escherichia coli and Immunostimulatory Effects on Human Peripheral Blood Mononuclear Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Membrane vesicles derived from the probiotic Lacticaseibacillus casei BL23 demonstrate antimicrobial properties against Escherichia coli and a potential biological effect in improving the overall survival of C. elegans infected with Pseudomonas aeruginosa. These vesicles stimulated immune responses in primary cells without causing toxicity. Our results

Targeting Post‐Irradiation Thyroid Dysfunction: Electrospun Scaffolds As A Dual‐Action Approach for Antioxidant and Immune Modulation

open access: yesAdvanced Healthcare Materials, EarlyView.
Radiation‐induced hypothyroidism follows head and neck radiotherapy due to oxidative stress and inflammation. Electrospun polycaprolactone scaffolds containing adenosine have potential to modulate thyroid repair. Scaffolds enhance thyrocyte proliferation, antioxidant enzymes glutathione peroxidase and catalase, reduce senescence and apoptosis markers ...

Co‐Electrospinning Extracellular Matrix with Polycaprolactone Enables a Modular Approach to Balance Bioactivity and Mechanics of a Multifunctional Bone Wrap

open access: yesAdvanced Healthcare Materials, EarlyView.
The incorporation of nondigested ECM and synthetic polymers into a co‐electrospinning system enables the decoupling of bioactivity and mechanical properties within a single wrap. This technique is used to develop a multifunctional bone wrap that achieves augmented membrane durability, sustained infection control, and enhanced vascularity for use in ...

Customizable Fabrication of 2D and Conformal Multielectrode Arrays for 3D Printed Organotypic Bioelectronic Interfaces

open access: yesAdvanced Healthcare Materials, EarlyView.
Aerosol jet printing enables rapid, customizable fabrication of flexible, fully gold multi‐electrode arrays (MEAs) for organotypic bioelectronic interfaces. The printed MEAs exhibit stable electrochemical performance, cytocompatibility, and functionality in recording and stimulation, including integration with 3D‐printed constructs.

Bioengineered Pancreatic Cancer Immunosuppressive Microenvironment Models for Screening Immunotherapies

open access: yesAdvanced Healthcare Materials, EarlyView.
Bioengineering tumor‐stroma pancreatic cancer models with potential to emulate the native immunosuppressive tumor microenvironment. Cancer‐on‐a‐bead models exhibited higher relevance for screening immunotherapies and modulating the protumoral PDAC microenvironment. ABSTRACT Pancreatic cancer is notably resistant to treatment, primarily due to its dense

A Sacrificial 3D Printed Vessel‐on‐Chip Demonstrates a Versatile Approach to Model Granulation Tissue

open access: yesAdvanced Healthcare Materials, EarlyView.
A novel method that combines 3D printing and organ‐on‐chip technology enables the creation of hollow channels lined with endothelial cells through a fibroblast‐populated connective tissue matrix. The model supports stable metabolic culture conditions, angiogenic sprouting, and immune cell migration, thereby demonstrating an easy and versatile method to

Plasma‐Polymerized Nanoparticles Presenting Fibrillin‐1 Drive Rapid Re‐Endothelialization of Vascular Grafts

open access: yesAdvanced Healthcare Materials, EarlyView.
Commercial vascular grafts are made from ePTFE, a highly hydrophobic, foreign material that fails at a high rate in small‐diameter applications. Plasma polymer nanoparticles (PPN) are a versatile material functionalisation tool, used here to present fibrillin‐1 fragment PF8 on the graft surface.

Infusible Extracellular Matrix Biomaterial Enhances Cell‐Specific Pro‐Repair Responses Following Acute Myocardial Infarction

open access: yesAdvanced Healthcare Materials, EarlyView.
We measure the cell‐specific responses of administering infusible ECM (iECM) in acute myocardial infarction (MI) across multiple timepoints. Using single‐nucleus RNA sequencing and spatial transcriptomics, we measure macrophage activation, fibroblast remodeling, increased vascular development, lymphangiogenesis, cardioprotection, and neurogenesis ...

A 3D Bioprinted Spheroid‐Laden dECM‐Enriched Osteosarcoma Model for Enhanced Drug Testing and Therapeutic Discovery

open access: yesAdvanced Healthcare Materials, EarlyView.
A 3D biomimetic OS model was developed by bioprinting an OS‐cell‐derived dECM‐enriched bioink with OS spheroids incorporated. The model showed upregulation of known OS prognostic markers and increased resistance to doxorubicin, compared to 2D cultures and scaffold‐free spheroids, making this a more clinically relevant platform for drug discovery ...
