Stimulation of collateral artery growth: travelling further down the road to clinical application

Area of Science:

• Cardiovascular biology
• Vascular medicine
• Regenerative medicine

Background:

• Collateral artery growth (arteriogenesis) is a critical defense against occlusive artery disease, preventing myocardial infarction and death.
• Arterial obstructive diseases are highly prevalent, making therapies that promote collateral vessel growth highly impactful globally.
• Despite promising experimental results, no drug has successfully translated to clinical practice due to efficacy or safety concerns.

Purpose of the Study:

• To review current knowledge on the mechanisms driving collateral artery growth.
• To examine the challenges hindering the clinical application of pro-arteriogenic treatments.
• To discuss future directions and novel strategies for stimulating vascular growth from bench to bedside.

Main Methods:

• Literature review of experimental and clinical studies on arteriogenesis.
• Analysis of mechanisms underlying collateral vessel development.
• Examination of clinical trial data and identified limitations.

Main Results:

• Arteriogenesis is a complex process involving multiple molecular pathways.
• Clinical translation of pro-arteriogenic therapies is hampered by insufficient efficacy and adverse effects.
• Existing therapeutic strategies have not met clinical needs for promoting collateral growth.

Conclusions:

• Understanding arteriogenesis mechanisms is key to developing effective treatments.
• Overcoming clinical translation barriers requires innovative therapeutic strategies.
• Future research should focus on safe and effective methods for stimulating vascular growth to combat occlusive artery disease.
