An investigation was carried out to determine the fine three-dimensional structure of pericytes in excised human vocal fold mucosa, by means of scanning and transmission electron microscopic observation. The results are summarized as follows. 1) There were many pericytes around the true capillaries, arterial capillaries, and venous capillaries in the vocal fold mucosa. 2) Newborns had pericytes around the capillaries in the vocal fold mucosa. 3) The pericytes had bulged fusiform or polygonal cell bodies and branching processes. The branching processes consisted of long and relatively thick longitudinal ones and short circumferential ones. 4) The cell body and processes of the pericytes encircled the capillaries, and the tips of the processes formed intercellular tight junctions with endothelial cells and made a firm connection with them. 5) The pericytes had many cytoplasmic filaments. 6) The pericytes in the vocal fold mucosa appeared to support and protect capillary walls in the vibrating tissue.
通过扫描电子显微镜和透射电子显微镜观察，对切除的人声带黏膜中周细胞的精细三维结构进行了研究。结果总结如下：1）声带黏膜中的真毛细血管、动脉毛细血管和静脉毛细血管周围有许多周细胞。2）新生儿声带黏膜中的毛细血管周围有周细胞。3）周细胞具有膨出的梭形或多边形细胞体和分支突起。分支突起由长且相对较粗的纵向突起和短的环形突起组成。4）周细胞的细胞体和突起环绕着毛细血管，突起的尖端与内皮细胞形成细胞间紧密连接并与之牢固相连。5）周细胞有许多细胞质细丝。6）声带黏膜中的周细胞似乎对振动组织中的毛细血管壁起到支持和保护作用。
