Isolation of two distinct populations of cells from rat kidney cortex and their use in the study of chemical-induced toxicity.

Procedures for the isolation and enrichment of cell populations from suspensions of rat kidney cortical cells were developed. Using Percoll density-gradient centrifugation, two populations of cells were obtained; marker enzymes [alkaline phosphatase and gamma-glutamyltransferase for proximal tubular (PT) cells and hexokinase for distal tubular (DT) cells… (More)
