Summary
Advanced microfluidic models using human cells offer a better way to test vascular implants. These endothelium-on-chip platforms improve assessment of endothelial function and reduce risks associated with vascular interventions.
Area of Science:
- Biomedical Engineering
- Vascular Biology
- Regenerative Medicine
Background:
- Vascular interventions can harm the endothelial glycocalyx and junction proteins, leading to thrombosis and increased permeability.
- Animal models for evaluating drug-coated implants show limitations due to species-specific differences in healing responses.
- Accurate prediction of late vascular complications requires better in vitro models that mimic human physiology.
Purpose of the Study:
- To review advances in microfluidic endothelium-on-chip platforms for evaluating vascular biomaterials.
- To highlight the potential of these systems in assessing endothelial function and vascular risks.
- To bridge the gap between animal studies and human clinical outcomes for endovascular implants.
Main Methods:
- Development of microfluidic platforms that replicate in vivo vascular environments.
- Integration of human-derived cells to create functionalized endothelium-on-chip models.
- Replication of physiologically relevant blood-flow patterns and intercellular crosstalk.
Main Results:
- Microfluidic platforms provide physiologically relevant in vitro vascular models.
- Endothelium-on-chip technology with human cells offers biologically relevant vascular assessments.
- These systems can provide critical data to complement animal study findings.
Conclusions:
- Microfluidic endothelium-on-chip platforms represent a significant advancement for evaluating vascular interventions.
- These models can accurately assess endothelial function, hyperpermeability, and thrombogenesis risks.
- They offer a valuable tool for the early stages of drug-coated endovascular implant development.
