注射到睾丸网的胶体硫化汞粘附在上皮细胞的静纤毛上，随后进入顶端细胞质中高度发达的小管系统。在静纤毛之间产生的细胞表面小管内陷导致细胞质空泡聚集颗粒物质。静纤毛、小管和空泡的界膜被一层无定形物质覆盖。据推测，这可能与离子交换树脂一样结合颗粒、分子和离子，并且它可能以这种方式在细胞摄取和运输物质中充当载体。
Colloidal mercuric sulfide injected into the rete testis adhered to the stereocilia of the epithelial cells and subsequently moved into a highly developed canalicular system in the apical cytoplasm. The canalicular invaginations of the cell surface arising between the stereocilia lead to cytoplasmic vacuoles that concentrate the particulate matter. The limiting membrane of the stereocilia and of the canaliculi and vacuoles is covered by a layer of amorphous material. It is speculated that this may bind particles, molecules, and ions as does an ion exchange resin, and that it may, in this way, act as a carrier in the uptake and transport of substances by cells.
