A collection of Nature papers marks a significant milestone in creating the Human Cell Atlas (HCA). This international collaboration aims to understand all human cells and their properties. The HCA will include 18 different atlases, each focused on a biological network like the Brain, Lung, or Gastrointestinal system. By identifying differences between healthy (reference) and diseased states, this Atlas could transform global healthcare. This conceptual illustration explores the groundbreaking journey toward a globally representative, comprehensive 3D interactive map of all human cell types.
