Sinir Sistemi Yeniden Yapılanma, Modülasyon ve Modelleme için Anatomik olarak İlham Almış Üç Boyutlu Mikro-Dokulu Mühendisli Sinir Ağları

Overview

This manuscript details the fabrication of micro-tissue engineered neural networks (micro-TENNs), which are three-dimensional constructs with aligned axonal tracts and aggregated neuronal populations within a hydrogel. These living scaffolds can reconstruct or modulate neural circuitry and serve as models for neurobiological studies.

Key Study Components

Area of Science

• Neuroscience
• Tissue Engineering
• Neurobiology

Background

• Micro-TENNs replicate brain connectome anatomy.
• They consist of long axonal tracts connecting neuronal populations.
• These constructs are designed for minimally invasive delivery into the brain.
• They can aid in reconstructing neural circuitry lost due to trauma or disease.

Purpose of Study

• To fabricate micro-TENNs for neural circuitry reconstruction.
• To create biofidelic models for neurobiological studies.
• To emulate the cytoarchitecture of brain pathways.

Methods Used

• Manual breaking of glass capillary tubes into fragments.
• Insertion of acupuncture needles into the fragments.
• Preparation of agarose solution for the constructs.
• Utilization of a tubular hydrogel for neuronal aggregation.

Main Results

• Successful fabrication of micro-TENNs that mimic brain structures.
• Demonstrated potential for reconstructing neural pathways.
• Established a method for creating living scaffolds for research.
• Highlighted challenges in working with micron-scale constructs.

Conclusions

• Micro-TENNs are promising tools for neuroscience research.
