Technique for cultivation of transitional epithelium from mammalian urinary bladder

A technique for initiating cultures of epithelial (urothelial) cells from mammalian urinary bladder has been described. Urothelial cells obtained by this method have been used to support replication of viruses and as controls for immunological, biochemical, chromosome, and electron microscopy studies. Both light and electron microscopic studies of cultured cells suggest that they are epithelial and not a mixed culture.
