✦ Synopsis

The lack of a suitable system to culture epithelial cells for a long period under a luminal-antiluminal medium gradient, was the reason to develop a new system. It consists of an interchangeable sheet of permeable support material, which is set in place by two tight fitting holding rings. For special demands the supports can be coated with extracellular matrix proteins improving cellular attachment and terminal differentiation. The handling of the sheets by forceps proceeds easily and quickly, thus fastening the transfer of cultured cells without additional manipulations. The sheets can be transferred to a newly developed microperfusion chamber on which an apical and a basal perfusion over a long culture period parallel to a transepithelial electrophysiological registration becomes possible. The chamber has an extremely low amount of fluid dead space. The separate perfusion of cultured cells under isotonic, hypotonic or hypertonic conditions opens new possibilities. Thus, culture can be performed under most natural conditions e.g., that found within the kidney.
