Developing Rat Lung Has a Sided Pacemaker Region for Morphogenesis-Related Airway Peristalsis
2 Dec 2004
Abstract excerpt
Prenatal airways from diverse species are capable of spontaneous peristaltic contractions in each trimester. The function of this smooth muscle activity is unknown. We demonstrate that peristalsis of the embryonic airway originates from a sided pacemaker focus, is stimulated in a calcium-dependent fashion by the pulmonary morphogen fibroblast growth factor-10 (FGF-10), and appears coupled to lung growth. Airway...
