Basic and Therapeutic Aspects of Angiogenesis Updated.

Area of Science:

• Cardiovascular Biology
• Endothelial Cell Biology
• Vascular Medicine

Background:

• Organisms beyond oxygen diffusion limits require functional vasculature.
• Endothelial cells exhibit organotypic heterogeneity, adapting to specific organ demands.
• Vascular dysfunction underlies diseases like cancer and diabetic microvasculopathies, requiring therapeutic intervention.

Purpose of the Study:

• To review recent advances in understanding endothelial cell behavior in health and disease.
• To identify novel molecular players and concepts for therapeutic targeting in vascular disorders.
• To address limitations of current anti-angiogenic and proangiogenic therapies.

Main Methods:

• Review of recent scientific literature on endothelial cell biology.
• Analysis of molecular mechanisms underlying vascular homeostasis and disease.
• Identification of potential therapeutic targets based on novel findings.

Main Results:

• Current anti-VEGF therapies show limited efficacy in solid tumors due to resistance mechanisms.
• Tumors utilize alternative growth factors and pathways to promote angiogenesis.
• Existing proangiogenic strategies face challenges with dosing, half-life, and retention.

Conclusions:

• Novel molecular players and concepts are emerging for targeting endothelial cell behavior.
• Therapeutic strategies need to overcome resistance and improve delivery for vascular regeneration.
• Further research into endothelial cell heterogeneity and function is crucial for developing effective treatments.
