Area of Science:

  • Biomaterials Science
  • Cardiovascular Research
  • Tissue Engineering

Background:

  • Cardiovascular diseases are a leading cause of death globally.
  • Current in vitro models (2D cultures) lack complexity, and in vivo models have limitations.
  • There is a need for advanced in vitro models that mimic the native heart environment.

Purpose of the Study:

  • To develop a novel hydrogel scaffold from decellularized porcine ventricular myocardium (dECM).
  • To evaluate the hydrogel's properties and its suitability for cardiovascular in vitro models.
  • To assess the potential of the dECM hydrogel in cardiac tissue engineering and disease modeling.

Main Methods:

  • Optimized decellularization strategy to preserve extracellular matrix (ECM) proteins.
  • Characterization of the dECM-based hydrogel's self-crosslinking, gelation, and stability.
  • Cytocompatibility assays with human bone marrow-derived mesenchymal stem cells and human umbilical vein endothelial cells.

Main Results:

  • The dECM hydrogel was successfully fabricated with preserved ECM structure.
  • The hydrogel demonstrated reproducible self-crosslinking, stable gelation kinetics, and good stability.
  • High cell viability and proliferation were observed, with increased cell densities in 2.5D and 3D cultures compared to 2D.
  • The dECM hydrogel effectively supported cardiovascular cell culture for in vitro model fabrication.

Conclusions:

  • The cardiac dECM-based hydrogel is a structurally preserved and biocompatible platform.
  • It supports both short- and long-term cell culture, mimicking the native myocardial environment.
  • This scaffold holds significant potential for cardiac tissue engineering, disease modeling, and cardiotoxicity screening.
