Insights
This review explores polymers and scaffolds for enhancing neovascularization in cardiovascular diseases. It highlights challenges in creating complex vascular networks for tissue engineering.
Area of Science:
- Biomaterials Science
- Regenerative Medicine
- Cardiovascular Research
Background:
- Cardiovascular diseases are a leading cause of global mortality and morbidity.
- Neovascularization is critical for restoring tissue function after cardiovascular lesions (e.g., ischemia, atherosclerosis).
- Existing treatments face limitations in effectively regenerating vascular tissue.
Purpose of the Study:
- To review recent advancements in polymers and scaffolds for promoting neovascularization.
- To emphasize the role of scaffold biocompatibility in stem cell behavior.
- To discuss the mechanisms of stem cell proliferation, migration, differentiation, and vascular network formation.
Main Methods:
- Literature review of current research on biomaterials for vascular tissue engineering.
- Analysis of studies focusing on synthetic polymers, polysaccharides, and proteins in scaffold design.
- Examination of stem cell interactions with biomaterial scaffolds.
Main Results:
- Polymers and scaffolds show promise in improving neovascularization.
- Biocompatibility of scaffolds is crucial for stem cell integration and vascularization.
- Combinations of synthetic polymers with natural materials enhance scaffold properties.
- Stem cell behavior (proliferation, migration, differentiation) is influenced by scaffold characteristics.
Conclusions:
- Advanced polymer-based scaffolds are key to enhancing neovascularization for cardiovascular repair.
- Optimizing scaffold biocompatibility and structure is vital for successful vascular tissue engineering.
- Despite progress, constructing complex vascular networks remains a significant challenge.
Abstract:
Cardiovascular diseases remain the leading cause of mortality or disabled quality of life for people over the world. The necessity of neovascularization is essential for re-establishing the tissue functions after a major lesion that occurs in patients with cardiovascular disorders, such as ischemia, atherosclerosis, diabetes, peripheral vascular disease and burn wounds. This review focuses on the recent data regarding the polymers and scaffolds that are used for improving neovascularization with emphasis on the biocompatibility and mechanisms involved in stem cells proliferation, migration, adherence, differentiation and organization in vascular networks. The newly emerging techniques used in conjugation of synthetic polymers with polysaccharides or proteins attempt to improve the biocompatibility of scaffolds, but the complex structures of blood vessels make their construction to remain a major challenge for the vascular tissue engineering.
