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 to 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.
晶体状内含物是树袋熊（Phascolarctos cinereus）睾丸支持细胞基部区域的常见特征。它们通常位于细胞核附近，无膜包被，是由微管组成的细长矩形结构，这些微管与晶体状内含物的长轴成直角排列，并沿该长轴平行排列成规则的行。相邻行中的微管以一定角度相互错开，并通过细丝广泛互连。晶体状内含物的组成和功能均未确定，但它们与张力丝的关联以及附近核糖体的存在表明它们很可能是蛋白质性质的。
