  • Review of existing literature on cardiac tissue engineering principles and materials.
  • Analysis of scaffold properties essential for cell integration and tissue function.
  • Discussion of biofabrication strategies and biomaterial choices for scaffold construction.

Main Results:

  • Artificial scaffolds are designed as 3D porous structures that emulate the native extracellular matrix.
  • Effective scaffolds facilitate cell adhesion, migration, differentiation, and proliferation.
  • Scaffolds must support cellular attachment, mechanical contractility, and electrical conductivity for cardiac applications.

Conclusions:

  • The selection of appropriate biofabrication techniques and biocompatible, biodegradable biomaterials is crucial for successful cardiac tissue engineering.
  • Advanced scaffolds can promote essential cell-electrical interactions, facilitating tissue repair.
  • Artificial scaffolds offer a promising avenue for overcoming current limitations in cardiovascular disease treatment and heart regeneration.
