    Research Summary

    Dr. Arend's laboratory studies the mechanisms of mammalian kidney development. Specifically, their studies involve various cell and molecular biology techniques to determine the role of the bioactive sphingolipid, sphingosine-1-phosphate (S1P), in organogenesis of the kidney. Their research indicates that S1P may be involved in development of conditions such as cystic kidney disease and Meckel syndrome. They also study the pathologic aspects of other kidney disease by various morphologic techniques, including light, immunofluorescence and electron microscopy.
