应用相关光镜和电镜技术研究了灵长类牙龈粘膜默克尔细胞的形态和分布。牙龈粘膜由复层鳞状上皮和致密的结缔组织基质组成。上皮与下面的结缔组织相互交错，形成长的相互连接的网脊。默克尔细胞及其相关的轴突在牙龈粘膜中丰富，它们单独或成簇地位于上皮网脊的基部。这些细胞具有与其他人描述的硬腭、毛状皮肤、无毛皮肤和眼睑中的默克尔细胞相同的形态。虽然个别默克尔细胞被发现在整个牙龈粘膜，默克尔细胞簇是最多的下颌舌牙龈粘膜。当与其他研究者的数据，这一发现相关联，它似乎是默克尔细胞簇位于优先在咀嚼粘膜与舌头密切接触，因此可能作为一个重要的来源，提供有价值的信息，舌在口腔中的位置的体感反馈。
The morphology and distribution of Merkel cells in primate gingival mucosa have been studied by correlated light and electron microscopic techniques. The gingival mucosa is composed of a stratified squamous epithelium with a dense underlying connective tissue stroma. The epithelium interdigitates with the underlying connective tissue forming long interconnected rete ridges. Merkel cells and their associated axons are abundant in gingival mucosa where they are located, either individually or in clusters, at the base of epithelial rete ridges. These cells have an identical morphology to Merkel cells described by others in the hard palate, hairy skin, glabrous skin and eyelid. While individual Merkel cells are found throughout the gingival mucosa, Merkel cell clusters are most numerous in the mandibular lingual gingival mucosa. When correlating this finding with data from other investigators, it appears that Merkel cell clusters are located preferentially in the masticatory mucosa in intimate contact with the tongue and thus may function as an important source of somatosensory feedback providing valuable information regarding the position of the tongue in the oral cavity.
