Three-Dimensional Neural Spheroid Culture: An In Vitro Model for Cortical Studies
Research Overview
Central nervous system models are in high demand for studying neurological disorders, injury, toxicity, and drug efficacy. 3D cultures bridge the gap between 2D culture and animal models by presenting an in vivo-like microenvironment in a tailorable platform — and among them, scaffold-free self-assembled spheroids avoid introducing foreign materials while preserving native cell populations and extracellular matrix.
This study generated 3D spheroids from primary postnatal rat cortical cells using an accessible, size-controlled, reproducible, and cost-effective method, establishing a practical neural model for labs without specialized equipment.
