Human sweat gland epithelial cells (SGECs) have been isolated and grown in vitro, However, slow proliferation makes the culture of these cells extremely difficult. The present study was carried out to explore the modified culture medium for SGECs in vitro. Full-thickness skin samples were minced (1 mm(3)) and digested overnight with type II collagenase. The gland coils were removed under an inverted phase-contrast microscope. An adherent culture method was used to isolate and culture SGECs. Staining with hematoxylin and eosin was performed, followed by observation of the morphologic features of these cells. Immunofluorescence staining with antibodies to cytokeratins CK7, CK18, and CK19 and carcinoembryonic antigen (CEA) was performed to verify the presence of SGECs. Growth curves by MTT were created for cells grown in serum-free keratinocyte medium and in modified keratinocyte medium containing 2.5% fetal bovine serum (FBS). One week after culturing, the cells grew well and were polygonal or irregular in shape by inverted phase contrast microscopy. Cell fusion, with a characteristic paving-stone arrangement, reached 100% after approximately 3 weeks in culture. Immunofluorescence staining indicated expression of CK7, CK18, CK19, and CEA. Compared with SGECs grown in serum-free keratinocyte medium, the proliferation of SGECs grown in modified culture medium with low concentration of FBS at days 6, 9, and 12 was significantly accelerated (p < 0.05). This study suggests that keratinocyte medium supplemented with 2.5% FBS is effective and suitable for the culture of SGECs.

A benign neoplasm derived from epithelial cells of sweat glands. (Stedman, 25th ed)
Sweat-producing structures that are embedded in the DERMIS. Each gland consists of a single tube, a coiled body, and a superficial duct.
A glandular epithelial cell or a unicellular gland. Goblet cells secrete MUCUS. They are scattered in the epithelial linings of many organs, especially the SMALL INTESTINE and the RESPIRATORY TRACT.
A cystic form of sweat gland adenoma (ADENOMA, SWEAT GLAND). It is produced by the cystic proliferation of apocrine secretory glands. It is not uncommon, occurring in adult life in no particular age group, with males and females equally affected. The commonest site is around the eye, particularly lateral to the outer canthus. It is cured by surgical removal. (Stedman, 25th ed; Rook et al., Textbook of Dermatology, 4th ed, p2410)
A benign, slow-growing tumor, most commonly of the salivary gland, occurring as a small, painless, firm nodule, usually of the parotid gland, but also found in any major or accessory salivary gland anywhere in the oral cavity. It is most often seen in women in the fifth decade. Histologically, the tumor presents a variety of cells: cuboidal, columnar, and squamous cells, showing all forms of epithelial growth.
