Mesothelial changes in the mesentery during intestinal regeneration. (A-C) Meso-1 labeling of the mesentery of normal uneviscerated animals shows a well-organized muscle layer with muscle fibers (MF) cut longitudinally and a weakly labeled overlying coelomic epithelium. (B&D) This organization is lost in the mesentery of 7-day regenerating animals where muscle fibers have disappeared and the mesothelium is mainly a one-cell layer (see cell labeled with arrowhead). Bar= 25 μ m.
