  • Unresolved question

What is the 3D spatial organisation of the different components of human heart tissue at the cellular and tissue levels?

  • Objective

Access to the microarchitecture of the components of the heart tissue of the cell (micrometer) scale to that of the body (centimeter).

  • Method
  1. Extract samples of fresh human heart wall (Left Ventricle)
  2. Reconstruct the samples using X-ray phase-contrast micro-tomography (2500 X-ray projections acquired at the Synchrotron at a micrometric resolution)
  3. Process the reconstructed volumes (multiscale segmentation)
  4. Analyse the binarised reconstructed volumes to quantify the features of the 3D microstructure and get the arrangement of the tissue components.
  5. Define new bio-marquers.
