Abstract:
:Several models for preparing and isolating human and animal gallbladder epithelial cells, including low-grade gallbladder carcinoma cells, as well as proposed systems for culturing these isolated epithelial cells are reviewed here. Several reports concerning tissue culture of the gallbladder are also reviewed. The cell culture systems are divided into monolayer cell culture on collagen-coated or uncoated culture dishes or other culture substrate and three-dimensional cell culture in collagen gel. To prepare and isolate gallbladder epithelial cells, digestion of the gallbladder mucosa, abrasion of the mucosal epithelial cells, and excision of epithelial outgrowth of mucosal explants are applied. In monolayer cell culture, most of the specific biological features of isolated and cultured cells characteristic to the gallbladder are gradually lost after several passages, though quantitative and objective analyses of the pathophysiology of cultured cells and their secretory substances can be performed. Tissue culture using explants of the gallbladder has mainly been used for physiological studies of the gallbladder, such as investigating the transport of water and electrolytes. In this tissue culture system, quantitative assessment is difficult, though the original and specific biological and histological characteristics of the gallbladder are retained. Three-dimensional collagen gel culture could be an ideal model combining monolayer cell culture and tissue culture systems, and create controllable conditions or environments when several biologically active substances, such as growth factors, proinflammatory cytokines and adhesion molecules, are added to the culture medium. Advantages and shortcomings of individual cultivation models are discussed, and selecting the culture model most appropriate to the purpose of the study will facilitate investigations of the biology and pathogenetic mechanisms of gallbladder diseases such as cholelithiasis.
