Enzymatyczna izolacja śródmiąższowych pęcherzyków zewnątrzkomórkowych mięśni szkieletowych

Overview

This protocol aims to isolate and purify skeletal muscle interstitial extracellular vesicles (SkM-EVs) from rodent muscle tissues using mechanical detachment, enzymatic dissociation, filtration, and differential ultracentrifugation. The isolated SkM-EVs provide insights into muscle homeostasis and diseases, offering potential applications as diagnostic biomarkers or therapeutic vehicles.
