Introduction: This study was designed to investigate the effects of granulocyte colony-stimulating factor (G-CSF) administration in rats for 6 weeks after traumatic brain injury (TBI). Methods: Adult male Wistar rats (n = 30) were injured with controlled cortical impact device and divided into four groups. The treatment groups (n = 10 each) were injected subcutaneously with recombinant human...

The local lymph node assay using 5-bromo-2-deoxyuridine (BrdU) with flow cytometry (LLNA: BrdU-FCM) is a modified LLNA that is used to identify skin sensitizers by counting BrdU-incorporated lymph node cells (LNCs) with flow cytometry. Unlike other LLNA methods (OECD TG 429, 442A and 442B) in which the CBA/J mouse strain is used, LLNA: BrdU-FCM was originally designed to be compatible with BALB...

To study naive and memory CD8 T cell turnover, we performed BrdU incorporation experiments in adult thymectomized C57BL/6 mice and analyzed data in a mathematical framework. The following aspects were novel: 1) we examined the bone marrow, in addition to spleen and lymph nodes, and took into account the sum of cells contained in the three organs; 2) to describe both BrdU-labeling and -delabelin...

We investigated nucleotide-labeling patterns during ongoing hair cell regeneration in the avian vestibular epithelium and during drug-induced regeneration in the avian auditory epithelium. For utricle experiments, post-hatch chicks received an injection of bromodeoxyuridine (BrdU) and were allowed to survive from 2 hours to 110 days after the injection. Utricles were fixed and immunoreacted to ...

Infection of biomedical devices is characterized by biofilm formation and colonization of surrounding tissue by the causative pathogens. To investigate whether bacteria detected microscopically in tissue surrounding infected devices were viable, we used bromodeoxyuridine (BrdU), a nucleotide analogue that is incorporated into bacterial DNA and can be detected with antibodies. Infected human tis...

Microbes are major agents mediating the degradation of numerous dissolved organic carbon (DOC) substrates in aquatic environments. However, identification of bacterial taxa that transform specific pools of DOC in nature poses a technical challenge. Here we describe an approach that couples bromodeoxyuridine (BrdU) incorporation, fluorescence activated cell sorting (FACS), and 16S rRNA gene-base...

These studies were designed to determine whether adult neurogenesis occurs in the dentate gyrus of the tree shrew, an animal phylogenetically between insectivores and primates, and to explore the possibility that this process is regulated by stressful experiences and NMDA receptor activation. We performed immunohistochemistry for cell-specific markers and the thymidine analog bromodeoxyuridine ...

The rat adrenal medulla consists mainly of low proliferating, highly differentiated parenchymal cells. By immunocytochemical techniques, two types of parenchymal cells can be identified, norepinephrine (NE)- and epinephrine (E)-storing cells. Bromodeoxyuridine (BrdU), a thymidine analogue often used to identify proliferating cells, can also be detected by immunocytochemical techniques. We devel...

Several recent findings indicate that intensity of neurogenesis in adult brain might be regulated by enzymes involved in the cell cycle. Therefore, in the present study, we investigated whether the inhibition of cyclin-dependent kinases (CDKs) evoked by intraventricular administration of purvalanol A may influence the proliferation of cells in the dentate gyrus (DG) of the rat hippocampus. Purv...

We have determined the in vivo effect of 5-bromodeoxyuridine (BrdU) administered to mice in the drinking water for various lengths of time on the performance of T and B lymphocytes in a number of experimental protocols. Young mice continuously exposed to BrdU fail to gain weight, and the lymphocytes recovered after a prolonged period of exposure are fewer in number than in control mice. The rec...
