Endojen nöral kök hücre etkinleştirme en az Medulla Spinalis Yaralanmalarında, fare modeli değerlendirmek için bir Neurosphere tahlil

Overview

This study presents a minimal spinal cord injury model in adult mice that preserves the central canal, which houses endogenous neural stem cells (NSCs). The impact of spinal cord injury on the behavior of neural precursor cells is investigated through a neurosphere assay, allowing for quantification of NSC activation and migration following injury.

Key Study Components

Area of Science

• Neuroscience
• Neuroregeneration
