A human tissue culture cell line from a transitional cell tumour of the urinary bladder: growth, chromosone pattern and ultrastructure.

Cell cultures were made from 18 human bladder tumours. Three cell lines were maintained for seven transfer generations, but all had a "fibroblastic" morphology and a normal diploid karyotype. A fourth line has been maintained for over 80 transfer generations. This was derived from a well differentiated papillary tumour of bladder. Morphologically the light and electron microscopic structure of the cells resembled that of bladder tumours. The cells formed tumour nodules, with a similar structure, when transplanted into hamster cheek pouches. There is a stem line chromosome number of 48. Karyotypes of 60% of the stem line cells had one extra chromosome in Group C and one in Group D.

The structure of tumours derived from mouse cells after "spontaneous" transformation in vitro.

The histological structure of 58 primary tumours derived from spontaneously transformed tissue culture cell lines from embryonic (14-16 days), young (3-20 days) and old (28-34 months) C3H and C57 mice is described. Although the cell lines were derived from a number of different organs the tumours were similar in morphology. The pattern was mixed, with "fibrosarcomatous", "myxoid", "epithelioid" and giant cell areas. The tumours resemble some types of haemangiopericytoma.
