Aislamiento confiable de microvasculares del sistema nervioso central en cinco grupos de vertebrados

Overview

This protocol describes a method to isolate microvessels from various regions of the central nervous system (CNS) in both lissencephalic and gyrencephalic vertebrates. By enabling the comparison of microvasculature across different CNS regions and individuals, this technique facilitates deeper insights into vascular structures. The protocol can be completed within a day without the need for ultracentrifugation or enzymatic dissociation.
