Ovarian transplants and surrounding hepatic tissue in different groups 3 weeks after transplantation. The transplants of the MG as shown in a contain follicles in varying stages of maturation, germ cells, and corpora lutea. The altered liver acini downstream of the transplant can be distinguished easily from the surrounding tissue by their glycogen depletion. b: The transplant of a nonovariectomized animal of CG2 that is beginning to fibrose. The hepatic tissue does not show any focal alterations. The transplant of an animal treated with toremifene (CG5) (c) contains follicular tissue and corpus luteum tissue similar to the transplants of MG. However, no morphological alterations of the liver acini downstream of the transplant can be detected. Paraffin sections, PAS stain. Original magnification, ×80.
