From coiled tubules to a secretory canaliculus: a new model for membrane transformation and acid secretion by gastric parietal cells.

abstract：:In animal species undergoing determinate growth, the making of a full-size adult body requires a series of coordinated growth events culminating in the cessation of growth that precedes sexual maturation. The merger between physiology and genetics now coming to pass in the Drosophila model allows us to decipher these ...
