Main Results:

  • Pericyte cell bodies showed lengthwise orientation with protrusions towards endothelium.
  • Pericytes were observed contacting multiple capillaries at branching points.
  • Vascular-associated cells, potentially telocytes, were identified outside the basal lamina and formed contact zones with endothelial cells.

Conclusions:

  • Detailed 3D visualizations of cardiac microvasculature and stroma were provided.
  • Enhanced insight into cardiac stromal cytoarchitecture, particularly vasculature, was achieved.
  • The findings contribute to advancing cardiac tissue engineering and therapeutic strategies.
