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.

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.

Cancer Stem cells (CSC) are defined as a population of cells found within a tumor that have characteristics similar to normal stem cells. Like normal stem cells they have the potential to self renew and differentiate. The cellular origin of these cancer stem cells--whether they originate from stem cells that have lost the ability to regulate ...

The cytoskeleton in tumor cells
Pathology - Research and Practice, 1982During the past few years several laboratories investigated the occurrence of cytoskeletal components in epithelial and mesenchymal cells by electron microscopy and/or immunocytochemical methods in a number of tumor types growing in vitro or in the body.

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.

Multiple myeloma and solitary plasmacytoma are common reticuloendothelial diseases. They involve primarily the bone marrow but have occasional extramedullary components. Numerous complications have been reported with these diseases. Despite modern modes of therapy, the prognosis remains grim. Myeloma and plasmacytoma are part of the continuum of B-Cell

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).

Imbalanced activity of the mechanism that controls cell division is a prerequisite for malignant transformation of a normal cell. The present review considers this multi-step mechanism, which is usually called the G1-S checkpoint. Besides, tumor cells are characterized by the presence of telomerase, an enzyme responsible for restoration of chromosome ...

Testicular cancer is rare, accounting for 1% to 2% of all male malignancies. Nearly 90% to 95% of tumors arising in testis are germ cell in origin. Other sites of malignant germ cell tumors include the retroperitoneum, mediastinum, sacrococcygeal region, and pineal gland. The highest incidence is seen in Scandinavian countries, particularly Denmark (1).

This review provides an overview of some of the recent pre-clinical and clinical developments in germ cell tumors.Recent epidemiological studies highlight the variations in the geographic and ethnic distribution of germ cell tumors and the changing incidence of seminoma versus nonseminoma in the population. Additional studies are continuing to identify
