The development of assays for measuring the survival of individual tumor cells revolutionized the study of experimental cancer therapy by enabling researchers to move from assessing the gross responses of tumors to measuring the survival of cells in the critical, clonogenic tumor-cell populations (1).

Nephron, 1978
A 15-year-old female with primary reninism presented with benign hypertension, normokalemia, normal aortagram and normal intravenous pyelogram. The diagnosis was suggested only by a remarkably elevated plasma renin activity (PRA). Selective catheterization of renal vein branches was necessary to make the diagnosis of a tumor.

Ghost cell tumors are a family of lesions that range in presentation from cyst to solid neoplasm and in behavior from benign to locally aggressive or metastatic. All are characterized by the presence of ameloblastic epithelium, ghost cells, and calcifications.

Ultrastructural Pathology, 1991
A case of islet cell tumor occurring in a patient with the multiple endocrine neoplasia type I syndrome is reported. Immunostaining for insulin was strongly positive in the tumor cells. Numerous dense-core granules of endocrine caliber were identified ultrastructurally.

Circulating tumor cells (CTCs) can be separated and characterized from normal hematopoietic cellular constituents by a variety of methods. Different strategies have included separation by physical characteristics, such as size or weight, or by biological characteristics, such as expression of epithelial or cancer-specific markers.

On the reversibility of tumor cells
Medical Hypotheses, 1981A review is given of several cases in which a neoplastic cell becomes a normal one. Emphasis is placed on the Lucké adenocarcinoma in the frog and on the case of terminal differentiation. The mysteries of cell fusion studies are discussed as well as the experiments of Mintz et al on teratocarcinoma of the mouse. In the case of the Lucké adenocarcinoma,

Investigations of cell clones isolated in vitro, or selected in vivo, have shown that tumor cell populations are heterogenous. The isolated cell clones or cell subpopulations originating from a single tumor may differ in a variety of biological and biochemical characteristics.

Current Opinion in Cell Biology, 2005
Invasion of cancer cells into surrounding tissue and the vasculature is an initial step in tumor metastasis. This requires chemotactic migration of cancer cells, steered by protrusive activity of the cell membrane and its attachment to the extracellular matrix.

Hematology/Oncology Clinics of North America, 1992
The development of modern surgical staging and effective chemotherapy regimens has markedly improved outcome of treatment of ovarian germ cell tumors. Almost all patients with completely resected tumors will survive their disease. Those with tumors other than dysgerminoma should all receive adjuvant chemotherapy. Patients with stage IA dysgerminoma can
