Our bodies still hold plenty of secrets, and scientists have just uncovered a doozy: the lungs play a key role in producing blood. Until now, this task was ascribed solely to bone marrow, but studies on mice at the University of California San Francisco (UCSF) have found that, surprisingly, the majority of the body’s platelets...

Cross-cell transport bears unexpected responsibility for sealing blood-retinal barrier
Suppression of transcytosis (vesicle traffic across cells), shown here as a red glow, seals off the blood-retinal barrier in mice after birth, contrary to previous beliefs that permeability depends mainly on tight junctions between cells. A cellular trafficking system called transcytosis may actually do most of the work in controlling the permeability of the...
