Figure 1. Light micrographs of the skin of adult Xenopus laevis. (a) Overall view of Bouin-fixed and azocarmin-aniline blue stained sections show mature granular glands (G), mucous glands (M), and the vacuolated stage (V) of premature granular glands. The glands lie in the dennis and open towards the surface via ducts. (b) Early stage in granular gland development where the cell membranes of the secretory cells are still intact. (c) Detail of the vacuolated stage. Cell membranes have now disappeared and the nuclei are situated at the periphery of the acinus, however, storage granules are still absent at this stage. (a) Bar, 100 lam. (b) Bar, 10 ~tm. (c) Bar, 10 I.tm.
