Scientists hope that future therapies could stimulate neurogenesis in the hippocampus for people suffering from neurodegenerative diseases. However, there remains a missing link: “neural progenitor cells,” which can differentiate into different neurons and glial cells. The researchers then turned the model onto 14 hippocampus samples belonging to recently deceased donors between the ages of 20 and 78. Once the samples had been run through their AI models, the team found that nine of those samples contained progenitor cells. But the discovery of these progenitor cells is definitely good news for scientists hunting for effective ways to treat neurodegenerative diseases.
