The ultrastructure of the epidermal cells surrounding the mouth of three newborn marsupial species, the Northern native cat Dasyurus hallucatus, the brush tail possum Trichosurus vulpecula and the Northern brown bandicoot Isoodon macrourus were examined. The presence of Merkel cells, highly sensitive touch receptors, would suggest that the sense of touch aids the relatively underdeveloped newborn marsupial to move from the urinogenital sinus to the pouch and to locate the teat.
对三种有袋类新生动物口部周围的表皮细胞超微结构进行了检查，这三种动物分别是北袋鼬（Dasyurus hallucatus）、帚尾袋貂（Trichosurus vulpecula）和北褐袋狸（Isoodon macrourus）。 Merkel细胞（高度敏感的触觉感受器）的存在表明，触觉有助于相对发育不全的有袋类新生动物从泌尿生殖窦移动到育儿袋并找到乳头。
