title: The growth and histological characteristics of a series of human bladder cancer xenografts.
abstract: Xenografts from human transitional cell carcinoma of the bladder (TCC) have been successfully established in CBA mice which had previously been immune-deprived by thymectomy and whole body irradiation with cytosine arabinoside pre-treatment. Xenografts were established from 3/17 patients with histological grade 2 tumours, 3/19 patients with histological grade 3 tumours, and one from a patient with a mixed transitional cell and squamous cell carcinoma. No xenografts were established from patients with histological grade 1 tumours. All the xenografts maintained the histological characteristics of their parent tumours in early passage, but some developed more prominent squamous features in later generations. Many of the xenografts were cystic.
