Tubulogenesis (IMAGE) Rice University Caption Researchers from Rice University and Baylor College of Medicine have shown they can initiate a process called tubulogenesis that is crucial to the formation of blood-transporting capillaries. In microscopic images taken a different times during a weeklong experiment, researchers tracked the changes in cells (green) and cell nuclei (orange) using fluorescent markers.
