Préparation d’une suspension unicellulaire à partir d’artères carotides de souris pour le séquençage unicellulaire

Overview

This study addresses the challenges of low cellular viability and large cell debris in vascular tissue dissociation by presenting a two-step cell digestion protocol specifically for mouse carotid arteries. The protocol yields a high viability single-cell suspension that is adaptable for other vessels, advancing techniques in cardiovascular research.

Key Study Components

Research Area

• Cardiovascular research
• Cell dissociation methods
• Single-cell analysis

Background

• Common issues with vascular tissue dissociation include low cellular viability and large debris.
• Effective dissociation methods are crucial for studying various cell types within blood vessels.
• Previous protocols may lack adaptability or require specialized equipment.

Methods Used
