Area of Science:

  • Vascular Biology
  • Microfluidics
  • Cell Biology

Background:

  • Endothelial cells (ECs) are crucial for vascular homeostasis and function.
  • Traditional in vivo and in vitro models present limitations in studying EC biology.
  • 3D models and microfluidics offer advanced in vitro systems mimicking in vivo conditions.

Purpose of the Study:

  • To develop and validate a robust, reproducible vessel-on-a-chip (VOC) model.
  • To enable controlled in vitro studies of endothelial cell mechanobiology and inflammation.
  • To provide a scalable platform for vascular research.

Main Methods:

  • Fabrication of a microfluidic chip with an endothelial cell monolayer.
  • Incorporation of a microvascular microenvironment.
  • Utilized a peristaltic pump for continuous media circulation and shear stress application.
  • Validated the model by monitoring EC alignment, E-selectin expression, and TNF-induced changes.

Main Results:

  • Demonstrated physiological levels of shear stress within the VOC.
  • Observed EC cellular alignment in response to shear stress.
  • Confirmed increased E-selectin expression and TNF-induced EC morphological changes.
  • Validated the model's utility for studying vascular inflammation.

Conclusions:

  • The developed VOC model is a promising tool for studying EC mechanobiology and inflammation.
  • This model offers a controlled and scalable approach for various vascular biology applications.
  • The VOC platform opens new avenues for research in inflammation, immune, and cancer cell migration.
