Two- and three-dimensional electron microscopic observation in the immature capillary of the human granulation tissue revealed cytoplasmic interdigitations (CID) between the endothelium and the pericyte. These were composed of a cytoplasmic projection and indentation, and there was a gap space without basement membrane-like components between the two cell membranes. Plasmalemmal vesicles were frequently found locating beneath and/or attached to the cell membranes at the indentated side of the interdigitation. Two kinds of cytoplasmic interdigitation, each having a characteristic configuration, were demonstrated. The CID which was composed of a cytoplasmic projection from the endothelium to the pericyte had a dull-shaped cytoplasmic projection, while the CID which was composed of a cytoplasmic projection from the pericyte to the endothelium had a slender and long finger-like configuration.
对人肉芽组织中未成熟毛细血管进行的二维和三维电子显微镜观察显示，内皮细胞和周细胞之间存在细胞质相互交错（CID）。这些由细胞质突起和凹陷组成，并且在两个细胞膜之间存在没有基底膜样成分的间隙空间。质膜小泡经常位于相互交错凹陷侧的细胞膜下方和/或附着于该细胞膜。证实了两种具有特征性形态的细胞质相互交错。由内皮细胞向周细胞的细胞质突起组成的CID具有钝形的细胞质突起，而由周细胞向内皮细胞的细胞质突起组成的CID具有细长的手指状形态。
