          Background: Development of the culture of renal epithelial cells in a serum-free growth medium was driven by the need to examine the effects of hormones and other effector molecules on differentiated cell function without interference from the complex mixture of substances in serum. The present report details this laboratory’s cumulative experience in the use of a defined growth medium for the propagation of epithelial cells from adult, fetal, and malignant human renal tissue. Methods: Routine cell culture technology was used to determine the capability of a defined growth medium to support the growth of renal epithelial cells isolated by collagenase dissociation of tissue from adult and fetal kidneys, renal cell carcinoma, and Wilms’ tumors. Results: The defined growth medium formulation consistently allows the isolation and growth of transporting renal epithelial cells from both normal adult and fetal kidneys. This growth medium only rarely supports the growth of epithelial cells from renal cell carcinomas and Wilms’ tumors. Conclusions: The method developed for the culture of human proximal tubule cells requires minimal cell culture expertise and equipment, and results in the repeatable isolation of transporting epithelial cell cultures that retain features of differentiated proximal tubule cells.

          Characterization of primary rabbit kidney cultures that express proximal tubule functions in a hormonally defined medium

          Primary cultures of rabbit-kidney epithelial cells derived from purified proximal tubules were maintained without fibroblast overgrowth in a hormone-supplemented serum-free medium (Medium RK-1). A hormone- deletion study indicated that the primary cultures derived from purified rabbit proximal tubules required all of the three supplements in Medium RK-1 (insulin, transferrin, and hydrocortisone) for optimal growth but did not grow in response to EGF and T3. In contrast, the epithelial cells in primary cultures derived from an unpurified preparation of rabbit kidney tubules and glomeruli grew in response to EGF and T3, as well as insulin, transferrin, and hydrocortisone. These observations suggest that kidney epithelial cells derived from different segments of the nephron grow differently in response to hormones and growth factors. Differentiated functions of the primary cultures derived from proximal tubules were examined. Multicellular domes were observed, indicative of transepithelial solute transport by the monolayers. The proximal tubule cultures also accumulated alpha- methylglucoside (alpha-MG) against a concentration gradient. However, little or no alpha-MG accumulation was observed in the absence of Na+. Metabolic inhibitor studies also indicated that alpha-MG uptake by the primaries is an energy-dependent process, and depends upon the activity of the Na+/K+ ATPase. Phlorizin at 0.1 mM significantly inhibited 1 mM alpha-MG uptake whereas 0.1 mM phloretin did not have a significant inhibitory effect. Similar observations have been made concerning the Na+-dependent sugar-transport system located on the lumenal side of the proximal tubule, whereas the Na+-independent sugar transporter on the peritubular side is more sensitive to inhibition by phloretin than phlorizin. The cultures also exhibited PTH-sensitive cyclic AMP synthesis and brush-border enzymes typical of proximal cells. However, the activities of the enzymes leucine aminopeptidase, alkaline phosphatase, and gamma-glutamyl-transpeptidase were lower in the cultures than in purified proximal-tubule preparations from which they are derived.
