Molecular Characterization of Epidermal Cytokines -- A Potential In Vitro Assay for Contact Dermatitis

Current in vivo and in vitro tests that monitor whole kidney function assess proximal tubular functions. Recently, however, agents have been implicated in producing direct toxicity in the more distal portions of the nephron. Current nephrotoxicity tests which evaluate only the proximal tubular function would miss these other agents. Dr. Smith is endeavoring to develop the first in vitro model for the assessment of distal tubular injury.
