ABSTRACT
Stereological analysis of the secretory cells of the pars intermedia of Xenopus laevis over a period of 3 days following the transfer of animals from a white to a black background has revealed that significant alterations in the ultrastructural appearance of these cells can be detected 8 h after the transfer. In particular, changes in the secretory granules and the rough endoplasmic reticulum were found to correlate well with previous reports concerning the melanocyte-stimulating hormone (MSH) content and the capacity for protein synthesis of the pars intermedia.
