Abstract: | Summary Crystalloid inclusions are a common feature in the basal region of Sertoli cells in the koala, Phascolarctos cinereus. Generally located near the nucleus, they are non membrane-bounded, slender rectangular structures composed of tubules which are orientated at right angles to the long axis of the crystalloid and regularly arranged in rows parallel to this long axis. The tubules in adjacent rows are offset from one another at definite angles and extensively interconnected by filaments. Neither the composition nor function of the crystalloids has been determined, but their association with tonofilaments and the presence of ribosomes in the vicinity suggests that they are most likely proteinaceous.The authors would like to thank Mr. D. Harbrow, Mr. S. Brown and Ms. B. Canty for technical assistance; the Queensland National Parks and Wildlife Service and the Victorian Ministry of Conservation (Fisheries and Wildlife Division) for providing permits to work on this protected species; the staff of the Lone Pine Koala Sanctuary, Brisbane, for their assistance in obtaining animals. This work was supported by a grant from the Australian Research Grants Committee, Number DI-77/15525 |
