Meso-1 labeling of the regenerating intestine (Days 7-10 of regeneration). Meso-1 immunoreactivity (A-D) and phase microscopy (E-H) of 7 and 10 day regenerating intestine. In the 7-dpe Meso-1 labeling (A&E) shows ingressing cells at the distal tip of the growing rudiment and (B&F) some immunoreactive cells within the connective tissue (arrows). In the 10-dpe rudiment, as regeneration progresses, Meso-1 labels (C&G) the forming muscle layer (ML) and (D&H) cells that underlie the basal lamina of the luminal epithelium (LE). CE-coelomic epithelium, CT-connective tissue. Bar = All 50 μ m except B& F 20 μ m.
