Blood nourishes every part of our body. It is generated every day to carry oxygen and food towards, and garbage away from every cell. Our lungs breathe in the oxygen that goes to the blood and remove carbon dioxide from it. Do lungs passively interact with circulating blood, or can they even generate new blood cells and spread them through the body?
Emma and colleagues wanted to test lungs as an active area of blood production. For this, they live imaged the blood cells within the lungs of mice. This amazing feat showed them platelets being born inside of the lung. And this pool of platelets were not a minority, but a significant part of blood count. Not only did they find platelet birth, but they also found blood stem cells living in the lung. These cells could, under certain conditions, help recover many types of blood cells! To know more about this exciting and profound discovery, please listen to Emma.
