Modulation of exocytosis of previously pinocytosed fluid by human fibroblasts.
A slow phase of linear exocytosis by fibroblasts of previously endocytosed fluid, succeeding the initial burst of release, is described. This is not due to cell lysis, is virtually abolished at 4 degrees C, and is retarded when the lysosomal system is expanded. It may reflect membrane recycling.
