Fabrication and Characterization of Small-Caliber Nanofibrous Vascular Scaffolds

A supplementary document detailing the development and in vitro testing of small-caliber vascular scaffolds. The study, authored by Ying Wang and uploaded to figshare in March 2026, describes the fabrication of core-shell nanofibers using coaxial electrospinning. The scaffolds incorporate endothelial cell derivatives and heparin for sustained release to promote endothelialization and anticoagulation.

Use Cases

• Analyzing fabrication methods for core-shell nanofibers based on coaxial emulsion electrospinning described in the document.
• Studying the effects of sustained heparin release on anticoagulant properties as detailed in the results.
• Evaluating in vitro patency test methodologies for small-caliber (<6 mm) vascular grafts using a closed-loop system.
• Investigating the impact of endothelial cell derivative incorporation on cell proliferation and hemocompatibility.

Strengths

• The document provides a detailed methodological description of coaxial electrospinning with specific component percentages (30% ECd, 10% heparin).
• Results include specific performance metrics for 4 mm diameter scaffolds, noting the absence of clots in in vitro patency tests.
• Released under a permissive CC-BY-4.0 license, allowing for reuse and adaptation.

Limitations

• The dataset is a 1.1 MB DOCX file; the underlying experimental data (e.g., raw measurements, columnar results) are not directly provided in a structured format.
• Column-level documentation is absent; field semantics must be inferred from the textual description after download.
• Row count is unknown, which may limit suitability assessment for quantitative analysis.
