BACKGROUND Laboratory large animal models are important for establishing the efficacy of stem cell therapies that may be translated into clinical use. The similarity of ovine and human cardiovascular systems provides an opportunity to use the sheep as a large animal model in which to optimize cell-based treatments for the heart. Recent clinical trials in humans using endogenous cardiovascular p...

Brush-shaped amphiphilic block copolymers were conjugated with a monoclonal antibody against CD105 (i.e., TRC105) and a macrocyclic chelator for (64)Cu-labeling to generate multifunctional theranostic unimolecular micelles. The backbone of the brush-shaped amphiphilic block copolymer was poly(2-hydroxyethyl methacrylate) (PHEMA) and the side chains were poly(L-lactide)-poly(ethylene glycol) (PL...

Angiogenesis, development of new blood vessels from previous blood vessels, is necessary for tumor growth and metastasis. During recent years, a lot of effort has been put into identifying markers of angiogenesis (Meng et al., 2012). CD105 is not only a marker that has an important role in angiogenesis (Nassiri et al., 2011) but also it is essential for proliferation of endothelial cells and st...

BACKGROUND Intraductal papillary-mucinous neoplasm (IPMN) of the pancreas is an increasingly diagnosed entity since its definition by the World Health Organization in 1996. It has a broad clinical spectrum ranging from benign to malignant tumors. Optimum treatment is controversial and a better understanding of the development of IPMN of the pancreas and identification of potential prognostic fa...

The possible different therapeutic efficacy of human mesenchymal stem cells (hMSC) derived from umbilical cord blood (CB), adipose tissue (AT) or bone marrow (BM) for the treatment of myocardial infarction (MI) remains unexplored. This study was to assess the regenerative potential of hMSC from different origins and to evaluate the role of CD105 in cardiac regeneration. Male SCID mice underwent...

Synovial membrane and synovial fluid represent a good source of mesenchymal stem cells. They have been regarded as a promising therapeutic tool for musculoskeletal regeneration. Synovium-derived mesenchymal stem cells have higher expression of CD44 and better chondrogenic potential in vitro than mesenchymal stem cells from other tissues. In this study we compared mesenchymal stem cells from syn...

Recent studies suggest that tumor-derived microvesicles (MV) act as a vehicle for exchange of genetic information between tumor and stromal cells, engendering a favorable microenvironment for cancer development. Within the tumor mass, all cell types may contribute to MV shedding, but specific contributions to tumor progression have yet to be established. Here we report that a subset of tumor-in...

Purpose: Angiogenesis is an important step in the process of cancer growth. The purpose of this study was to determine the neoangiogenesis with CD31, CD34 and CD105, and tried to observe the differences between these three antibodies. Material/Methods: The blood vessels stained with CD31, CD 34 and CD105 were counted, and we reported their number per square millimeter to obtain microvascular de...

background and objectives: angiogenesis is essential for growth and metastasis of solid malignancies. tumor vessel count and expression of vascular endothelial growth factor (vegf), a potent angiogenic factor, have been associated with prognosis. this study was designed to assess vessels density by using cd31 and cd105 (endoglin) and their correlation with expression of vegf and proliferative i...

BACKGROUND Both VEGF and CD105 (endoglin) have been identified as markers of tumor angiogenesis and prognosis in breast cancer. They have always been studied in this kind of tumor by means of immunological methods. OBJECTIVE To study, by means of reverse-transcription polymerase chain reaction (RT-PCR), the expression of VEGF and CD105 (endoglin) at the mRNA level in a series of breast cancer...
