Fetal signaling pathways may offer future targets for treating lung injury

PHILADELPHIA — Specialized lung cells appear in the developing fetus much earlier than scientists previously thought. A new animal study published this week in the Proceedings of the National Academy of Sciences reports how cells that become alveoli, the tiny compartments in which gas exchange occurs in the lung, begin their specialized roles very early…
