Ferric Chloride-Induced Arterial Thrombosis and Sample Collection for 3D Electron Microscopy Analysis.

Area of Science:

• Cardiovascular Biology
• Hemostasis and Thrombosis Research
• Vascular Medicine

Background:

• Cardiovascular diseases are a major global health burden, with aberrant thrombosis contributing to significant mortality and morbidity.
• Thrombosis is implicated in systemic conditions (diabetes, obesity) and chronic inflammatory diseases (atherosclerosis, cancer, autoimmune disorders).
• Vascular injury triggers a complex interplay of coagulation, platelets, and endothelium to form clots, with dysregulation leading to bleeding or thrombosis.

Purpose of the Study:

• To describe the methodology for inducing and monitoring FeCl3-induced arterial thrombosis in vivo.
• To highlight the utility of this model for studying thrombosis mechanisms and evaluating antithrombotic therapies.
• To provide guidance on sample collection for ultrastructural analysis via electron microscopy.

Main Methods:

• Induction of arterial thrombosis using ferric chloride (FeCl3) in the carotid artery.
• Monitoring of vascular damage and subsequent clot formation.
• Sample preparation for electron microscopy analysis of thrombus ultrastructure.

Main Results:

• The FeCl3 model provides a sensitive and quantitative assay for assessing vascular damage and thrombosis.
• This technique allows for the study of molecular mechanisms and platelet ultrastructural changes during thrombus development.
• The model is effective for evaluating the efficacy of antithrombotic and antiplatelet agents.

Conclusions:

• The FeCl3-induced carotid injury model is a robust and versatile tool for thrombosis research.
• This standardized technique facilitates in-depth investigation of thrombosis pathogenesis and therapeutic interventions.
• The model supports the study of molecular events and ultrastructural dynamics in thrombus formation.
