A series of histochemical tests performed on the mantle of the northern quahog Mercenaria mercenaria L. suggest that the epithelium of the inner surface of the first fold and the underlying secretory cells function together in the formation of the periostracum in this mollusk. The secretory cells supply a phenolic substrate which, when oxidized, provides quinones capable of tanning the periostracum.
一系列针对北方圆蛤 Mercenaria mercenaria L. 套膜的组织化学测试表明，在这种软体动物中，第一褶皱内表面的上皮组织和下面的分泌细胞共同作用形成壳皮。分泌细胞提供酚类基质，基质氧化后产生醌类物质，能够鞣制壳皮。
