Buckling‐Resistant and Trace‐Stacked (BRATS) Design Enables Aid‐Free Implantation of Flexible Multielectrode Array with Minimized Inflammatory Tissue Response

Advanced Functional Materials, EarlyView.
Buckling‐resistant and trace‐stacked (BRATS) intracortical microelectrode arrays (MEAs) eliminate the need for insertion aid and complex surgical setup, resulting in minimal inflammatory tissue response, compared to conventional flexible MEAs inserted with aid. Trace stacking effectively doubled the channel count without increasing the MEA shank width,

Foreign body responses in central nervous system mimic natural wound responses and alter biomaterial functions [PDF]

, 2019
Biomaterials hold promise for diverse therapeutic applications in the central nervous system (CNS). Little is known about molecular factors that determine CNS foreign body responses (FBRs) in vivo , or about how such responses influence biomaterial ...

The development of a ε-polycaprolactone (PCL) scaffold for CNS repair [PDF]

, 2012
Potential treatment strategies for the repair of spinal cord injury (SCI) currently favour a combinatorial approach incorporating several factors, including exogenous cell transplantation and biocompatible scaffolds. The use of scaffolds for bridging the

Redistribution of metabolic resources through astrocyte networks mitigates neurodegenerative stress

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance Astrocytes respond to neuronal energy needs by mobilizing metabolic stores. How these resources are mobilized during neurodegeneration, especially in nearby regions that are not actively degenerating, could impact new therapeutic approaches.

A 3D Biofabricated Disease Model Mimicking the Brain Extracellular Matrix Suitable to Characterize Intrinsic Neuronal Network Alterations in the Presence of a Breast Tumor Disseminated to the Brain

Advanced Functional Materials, EarlyView.
A 3D disease model is developed using customized hyaluronic‐acid‐based hydrogels supplemented with extracellular matrix (ECM) proteins resembling brain ECM properties. Neurons, astrocytes, and tumor cells are used to mimic the native brain surrounding.

Exploring the Production of Extracellular Matrix by Astrocytes in Response to Mimetic Traumatic Brain Injury [PDF]

, 2016
Following injury to the central nervous system, extracellular modulations are apparent at the site of injury, often resulting in a glial scar. Astrocytes are mechanosensitive cells, which can create a neuroinhibitory extracellular environment in response

The spectrum of Ischemia-induced white matter injury varies with age [PDF]

, 2013
Stroke is a neurological condition that targets the whole range of the human population, from the pre-term infant to the elderly and is a major cause of death worldwide (Ingall 2004).

Mesenchymal stem cell-derived exosomes as a nanotherapeutic agent for amelioration of inflammation-induced astrocyte alterations in mice

Theranostics, 2019
Mesenchymal stem cell-derived exosomes (MSC-Exo) have robust anti-inflammatory effects in the treatment of neurological diseases such as epilepsy, stroke, or traumatic brain injury.

Astrocyte‐Guided Maturation of Neural Constructs in a Modular Biosynthetic Hydrogel for Biohybrid Neurotechnologies

Advanced Functional Materials, EarlyView.
A modular biosynthetic PVA–gelatin hydrogel crosslinked via visible‐light thiol‐ene chemistry is engineered as a coating for neural electrodes. Optimizing matrix composition and mechanical properties enables the hydrogel to support astrocytic populations that guide neural differentiation and functional maturation.
