7. Warren’s Research in the 1930s

Warren’s emerging expertise in videomicroscopy led to a major discovery almost immediately. In early April of 1930, he presented a paper, entitled “Moving pictures of normal cells,” at the 46th Annual Session of the American Association of Anatomists, in Charlottesville, Virginia. He described how:each cell type has its peculiar mode of migration. Lymphocyte migration is intermittent. From rest and spherical form they suddenly dart off, elongate, and move for one to several minutes, then stop, become spherical and rest for one to three minutes…[they] tend to move zigzag in a given direction, but may sometimes turn about… .Polymorphonuclear migration is continuous. They dart about in various directions. Macrophages rapidly change form and move about in an irregular manner by means of thin waving film-like pseudopodia which vary enormously in extend under different conditions. By means of these pseudopodia they take up debris and fluid globules of various sizes. The latter pass from the periphery to the body of the cell, often fuse on the way, and then rapidly shrink. Under certain conditions, relatively enormous amounts of fluid thus pass through these cells.1
