CD31(+) T cells, or so-called "angiogenic T cells," have been shown to demonstrate vasculoprotective and neovasculogenic qualities. The influence of age on CD31(+) T-cell number and function is unclear. We tested the hypothesis that circulating CD31(+) T-cell number and migratory capacity are reduced, apoptotic susceptibility is heightened, and telomere length is shortened with advancing age in...

The use of autologous cells harvested and subsequently transplanted in an intraoperative environment constitutes a new approach to promote regeneration. Usually cells are isolated by selection methods such as fluorescence- or magnetic- activated cell sorting with residual binding of the antibodies or beads. Thus, cell-based therapies would benefit from the development of new devices for cell is...

background : immunological response of host and parasite play a key role in developing vaccina­tion and immunization. the present study deals with the immune response and effecter mechanism, which was confirmed by migration inhibition factor (mif).  methods : the present work was conducted in parasitological lab of postgraduate department of zool­ogy, government holkar science college, indore (...

Stromal stem cells proliferate in vitro and may be differentiated along several lineages. Freshly isolated, these cells have been too few or insufficiently pure to be thoroughly characterized. Here, we have isolated two populations of CD45-CD34+CD105+ cells from human adipose tissue which could be separated based on expression of CD31. Compared with CD31+ cells, CD31- cells overexpressed transc...

BACKGROUND Angiogenesis plays a role in the progression of osteosarcoma, as well as in other mesenchymal tumors and carcinomas, and it is most commonly assessed by vascular endothelial growth factor (VEGF) expression or tumor CD31-positive microvessel density (MVD). Tumor VEGF expression is predictive of poor prognosis, and chemotherapy can affect the selection of angiogenic pattern. The aim of...

Background: Alcoholic liver disease (ALD) remains a major cause of morbidity and mortality world - wide. Liver biopsy is the gold standard method to assess presence fibrosis , useful in determining staging severity hepatic injury. To interpret biopsies, Reticulin stain, CD31,an immunohistochemical marker, which plays an important role degree disease, were used evaluation it. Methods: 50 Disease...
