Purpose of the Study:

  • To develop a modular microfabrication approach for creating functional cardiovascular tissue composites.
  • To quantitatively assess the impact of microarchitecture on cardiomyocyte function and vascular network formation.
  • To establish a platform for studying structure-function relationships in engineered cardiac tissues.

Main Methods:

  • Micromolding of separate cardiac and endothelial cell modules.
  • Assembly of micromolded modules into functional cardiovascular tissue composites.
  • Quantitative assessment of cellular function, including cardiomyocyte alignment, anisotropic contraction, and vascular network formation.

Main Results:

  • The modular assembly approach successfully created functional cardiovascular tissue composites.
  • Engineered tissues demonstrated synchronous contraction, indicating preserved cellular function.
  • The platform enabled quantitative assessment of microarchitecture's effect on cellular behavior.

Conclusions:

  • This modular microfabrication strategy provides a powerful tool for engineering functional cardiovascular tissues.
  • The developed platform facilitates the quantitative study of structure-function relationships in the heart.
  • This approach holds promise for advancing cardiovascular research and regenerative medicine.
