The updated version of the EFSUMB guidelines on the application of non-hepatic contrast-enhanced ultrasound (CEUS) deals with the use of microbubble ultrasound contrast outside the liver in the many established and emerging applications.

Endothelial cell (EC) dysfunction has been reported in cystic fibrosis (CF) patients. Thus, the availability of CF EC is
paramount to uncover mechanisms of endothelial dysfunction in CF. Using collagenase digestion, we isolated cells from
small fragments of pulmonary artery dissected from non-CF lobes or explanted CF lungs. These cells were a
heterogeneous mixture, containing variable percentages of EC. To obtain virtually pure pulmonary artery endothelial cells
