Pitt/McGowan Institute team discovers stem cells in the esophagus
Despite previous indications to the contrary, the esophagus does have its own pool of stem cells, said researchers from the University of Pittsburgh School of Medicine in an animal study published online today in Cell Reports. The findings could lead to new insights into the development and treatment of esophageal cancer and the precancerous condition known as Barrett’s esophagus. The research team grew pieces or “organoids” of esophageal tissue from mouse samples, and then conducted experiments to identify and track the different cells in the basal layer of the tissue. They found a small population of cells that divide more slowly, are more primitive, can generate specialized or differentiated cells, and have the ability to self-renew, which is a defining trait of stem cells.
