Background: Although well-acknowledged in vivo, spontaneous death of cancer cells in vitro is less widely appreciated.

Materials And Methods: Colony formation was studied in untreated control plates of standard clonogenic assays and measurements of actual and potential doubling times performed in asynchronous cultures of human cancer cells lines. Western blotting of lung large cell carcinoma, COR-L23 cells actively undergoing spontaneous cell death was also carried out.

Tumour heterogeneity is becoming increasingly important as an obstacle to genomic and proteomic technologies designed to improve the diagnosis and treatment of human cancer. In a panel of 19 human in-vitro cancer cell lines, we show marked heterogeneity of proteomic expression of key genes responsible for the control of cell division and death. Patterns of expression of these proteins were unique for each cell line.
