Abstract:
Therapeutic angiogenesis utilizing genetic and cellular modalities in the treatment of arterial obstructive diseases continues to evolve. This is, in part, because the mechanism of vasculogenesis, angiogenesis, and arteriogenesis (the three processes by which the body responds to obstruction of large conduit arteries) is a complex process that is still under investigation. To date, the majority of human trials utilizing molecular, genetic, and cellular modalities for therapeutic angiogenesis in the treatment of peripheral artery disease (PAD) have not shown efficacy. Consequently, the current available knowledge is yet to be translated into novel therapeutic approaches for the treatment of PAD. The aim of this review is to discuss relevant scientific and clinical advances in therapeutic angiogenesis and their potential application in the treatment of ischemic diseases of the peripheral arteries. Additionally, this review article discusses past and recent developments, such as some unconventional approaches that have the potential to be applied as therapeutic targets. The article also includes advances in the delivery of genetic, cellular, and bioactive endothelial growth factors.
Insights
Therapeutic angiogenesis for arterial obstructive diseases shows promise but faces challenges. Research is exploring genetic, cellular, and growth factor delivery for peripheral artery disease (PAD) treatment.
Area of Science:
- Cardiovascular Research
- Regenerative Medicine
- Vascular Biology
Background:
- Therapeutic angiogenesis aims to treat arterial obstructive diseases by promoting new blood vessel formation.
- Mechanisms of vasculogenesis, angiogenesis, and arteriogenesis are complex and still under investigation.
- Current human trials for peripheral artery disease (PAD) using genetic and cellular methods have shown limited efficacy.
Purpose of the Study:
- To review scientific and clinical advances in therapeutic angiogenesis for peripheral artery disease.
- To discuss the potential application of these advances in treating ischemic peripheral artery diseases.
- To explore novel and unconventional therapeutic targets and delivery methods.
Main Methods:
- Review of scientific literature and clinical trial data on therapeutic angiogenesis.
- Analysis of genetic, cellular, and bioactive growth factor delivery systems.
- Evaluation of past and recent developments, including unconventional approaches.
Main Results:
- Despite ongoing research, translating therapeutic angiogenesis into effective PAD treatments remains a challenge.
- Advances in delivery systems for genetic, cellular, and growth factors are crucial.
- Unconventional approaches may offer new therapeutic avenues.
Conclusions:
- Therapeutic angiogenesis research for PAD is evolving, but clinical translation is lagging.
- Further investigation into complex vascularization mechanisms is needed.
- Novel delivery strategies and targets are essential for future PAD therapies.
