Objective(s): Intracerebral injection of bone marrow stromal cells (BMSCs) is being investigated as a therapeutic tool to prevent Alzheimer's disease (AD). Our aim was to investigate the effects of BMSCs by intrathecal injection in AD rat model. Materials and Methods: BMSCs were obtained from the bone marrow of Wistar rat and transplanted into AD rat model via intrathecal injection. The rat mod...

background: various responses and different prognosis to specific treatment in different patients from one hand, and importance of ifn-γ producer cells on the other hand impressed us to study tc1. methods: the study was conducted in ghaem medical center and bu-ali research institute, mashhad university of medical sciences, iran from 2001 to 2002. lymphocytes of 36 patients were counted and cult...

Immunofluorescence and immunoperoxidase techniques were used to localize a cell surface chondroitin-sulfate proteoglycan antigen, termed NG2, in the developing and adult rat cerebellum. In the adult, both polyclonal and monoclonal anti-NG2 antibodies labeled cells throughout the cerebellar cortex, with the labeled cells being especially prominent in the molecular layer. The labeled cells had sm...

We have investigated the spatial pattern of epithelial cell cycling in a mutant strain of Hydra magnipapillata (sf-1). This strain has temperature sensitive interstitial stem cells and thus polyps containing only epithelial cells can be obtained by growth at the restrictive temperature. Epithelial animals were pulse labeled with the thymidine analog 5'-bromo-2'-deoxyuridine (Brdu) and stained w...

Stem cells appear to retain labeled DNA for extended periods because of their selective segregation of template DNA strands during mitosis. In this study, proliferating cells in the prepubertal bovine mammary gland were labeled using five daily injections of 5-bromo-2-deoxyuridine (BrdU). Five weeks later, BrdU-labeled mammary epithelial cells were still evident. The percentage of BrdU-labeled ...

Giant HeLa cells, having a spread diameter of about 200 micrometers, were briefly surface-labeled at 0 degree C with 125I-labeled transferrin, low density lipoprotein, anti-HeLa cell antibody, or concanavalin A. The cells were washed at 0 degree C, fixed, and autoradiographed. The distribution of grains when either anti-HeLa cell antibodies or concanavalin A was used was roughly as expected: th...
