Making Medicine Personal (IMAGE) Cincinnati Children's Hospital Medical Center Caption This confocal microscopic image shows a two-month-old human esophageal organoid bioengineered by scientists from pluripotent stem cells. About 700 micrometers (0.027 inches) in size, the organoid is stained to visualize key structural proteins expressed in mature esophagus, such as involucrin (green) and cornulin (blue). Researchers report in the journal Cell Stem Cell the organoids enhance the study of esophageal disorders, personalized medical and the development of regenerative tissue therapies for people.
