Overview

Randomized trial identifies factors limiting endothelial cell proliferation in adult hearts, suggesting new cardiac therapies.

Key Points

  • This research aims to explore how cardiomyocyte factors affect endothelial cell proliferation and angiogenesis.
  • Co-cultured endothelial cells with cardiomyocytes at different maturation stages.
  • Constructed ligand-receptor interactome using RNA-sequencing datasets.
  • Used gain- and loss-of-function studies in Cas9 mice to identify and test key anti-angiogenic molecules.
  • Adult cardiomyocytes significantly suppressed endothelial cell proliferation.
  • Identified 20 factors and 118 potential interactions between cardiomyocytes and endothelial cells.
  • In vivo deletion of KCNJ11 and CD74 genes increased endothelial cell proliferation and vessel formation.
