Distinction between 5-bromodeoxyuridine labeled and unlabeled mitotic cells by flow cytometry

Evaluation of DNA-content of Peritoneal Lavage Cells by Flow Cytometry in Patients with Gasteric Cancer

Background & Aims: Gastric cancer is the second common cancer in Iran and it has unfortunately no diagnostic signs in early stages. Considering the role of genetic and environmental factors in the development of gastric cancer, this study aimed at evaluating DNA-content of stomach cells in patients with gastric cancer in order to find a reliable index for prediction of disease prognosis and pro...

Suppression of Pigmentation in Mouse Melanoma Cells by 5-bromodeoxyuridine

Low concentrations (1-3 microg/ml) of 5-bromodeoxyuridine (BrdU) reversibly suppress pigmentation in a highly pigmented clone (B(5)59) of cultured B16 mouse melanoma cells. We have found that unpigmented cells (clone C(3)471), derived by long-term culture of B(5)59 cells in 1 microg of BrdU/ml, were completely amelanotic with no biochemically or cytochemically detectable tyrosinase activity or ...

Tumor distribution of bromodeoxyuridine-labeled cells is strongly dose dependent.

Bromodeoxyuridine (BrdUrd) is used extensively to measure the fraction of proliferating cells in tumors. Unlike endogenous markers of proliferation such as proliferating cell nuclear antigen (PCNA) and Ki-67, BrdUrd is exogenously administered and reaches the tumor via vasculature where it must then diffuse throughout the tissue to label S-phase cells. In this study, we examine the dose depende...

Cell kinetics in human malignancies studied with in vivo administration of bromodeoxyuridine and flow cytometry.

Bromodeoxyuridine (BrdUrd) is a pyrimidine analogue which is incorporated into the DNA of proliferating cells. When in vivo BrdUrd infusion is coupled with bivariate flow cytometry to measure cell BrdUrd incorporation and DNA content, both the percentage of DNA-synthesizing cells [BrdUrd-labeling index (LI)] and the DNA synthesis time (TS) can be determined on the same tissue sample. From exper...
