Abstract
During the peri-implantation stages, the mouse embryo radically changes its appearance, transforming from a hollow-shaped blastocyst to an egg cylinder. At the same time, the epiblast gets reorganized from a simple ball of cells to a cup-shaped epithelial monolayer enclosing the proamniotic cavity. However, the cavity’s function and mechanism of formation have so far been obscure. Through investigating the cavity formation, we found that in the epiblast, the process of lumenogenesis is driven by reorganization of intercellular adhesion, vectoral fluid transport, and mitotic paracellular water influx from the blastocoel into the emerging proamniotic cavity. By experimentally blocking lumenogenesis, we found that the proamniotic cavity functions as a hub for communication between the early lineages, enabling proper growth and patterning of the postimplantation embryo.

With what felt like a grizzly in his chest, Jim Benfield’s legs buckled, and he crashed onto his living room floor. A Mount Holly policeman who had helped first responders break down doors to rescue ailing 911 callers, he frantically fumbled with his cellphone.
“Dummy me, why didn’t I call the ambulance?” he shrugs. “I knew I was dying, and all I could think was that I wanted to speak to my wife one more time.”
As he stepped out of the shower, a clot blocked the left anterior descending artery of Benfield’s heart, triggering paroxysms of pain that he compares to the claws of an angry bear.
