Small diameter vascular grafts: progress on electrospinning matrix/stem cell blending approach

Area of Science:

• Biomaterials Science
• Regenerative Medicine
• Vascular Surgery

Background:

• Small diameter vascular grafts (SDVGs) face challenges in achieving biocompatibility and patency comparable to native vessels.
• Electrospinning (ES) offers a scalable method for creating extracellular matrix-like fibrous scaffolds.
• Stem cells (SCs) are valuable for cell therapy and regenerative medicine due to their multifunctionality.

Purpose of the Study:

• To review recent advances in SDVGs utilizing electrospinning (ES) matrices and stem cells (SCs).
• To discuss the integration of ES scaffolds and various types of SCs (pluripotent, multipotent, unipotent).
• To identify current challenges and future directions in the development of advanced SDVGs.

Main Methods:

• Literature review of studies on electrospinning scaffolds for vascular grafts.
• Analysis of research incorporating stem cells (SCs) into vascular graft designs.
• Synthesis of findings on the combined use of ES matrices and SCs for SDVG applications.

Main Results:

• Electrospinning (ES) matrices provide a versatile platform for creating biomimetic scaffolds for SDVGs.
• Stem cells (SCs), including pluripotent, multipotent, and unipotent types, enhance graft integration and function.
• The combination of ES matrices and SCs shows significant potential for overcoming limitations in current SDVG technology.

Conclusions:

• Integrating electrospinning (ES) matrices with stem cells (SCs) represents a promising strategy for developing next-generation small diameter vascular grafts (SDVGs).
• Further research is needed to address challenges and fully realize the potential of these advanced vascular graft technologies.
• This approach holds promise for improving clinical outcomes in vascular reconstruction.
