3.25 in. x 4 in. Lantern Slides, Images such as these indicated that secretory granules closely and selectively approach the apical membrane of the pancreatic acinar cell where exocytosis takes place, fuse with the apposed membrane, and release the content of secretory proteins into the acinar lumen without broaching the intracellular environment. The resulting omega figure is transitory, suggesting that the excess granule membrane is retrieved/recycled. Note the actin coat around the newly inserted granule membrane.

Yale University News Bureau announcement: “Yale measles researchers, who contributed to the testing of the two new measles vaccines licensed recently, are now busy studying the vaccines themselves. Here Professor Francis Black, who is studying antibody formation by the live and killed virus vaccines, inoculates measles cultures using mouth pipetting.
