title: Morphological responses of prostatic carcinoma to testosterone in organ culture.
abstract: Slices of human prostatic adenocarcinoma obtained by transurethral resection were maintained in organ culture for 4 days. Preservation of histological appearance was good with little evidence of necrosis within the viable tissue. Slices of tumour cultured in the presence of testosterone showed a morphological change to a more differentiated type of neoplasm whereas explants cultured in the absence of steroid hormone, or with stilboestrol diphosphate, showed no change. In the case of a relatively anaplastic tumour, testosterone produced a significant increase in the number of mitotic figures seen.
