Angiogenesis is essential for tumor growth and metastasis. There are conflicting reports as to whether microvessel density (IMD) in breast cancers is associated with prognosis. This could be due to the use of different antibodies to endothelial cell markers, variation in tissue pretreatment protocols, and nonstandardized counting methods. We have assessed the IMD in 106 breast carcinomas using ...

Introduction An increased number of tumor infiltrative lymphocytes (TILs) is considered a favorable prognostic factor in various cancers because it is a marker of antitumoral activity of the immune system. In this prospective, non-randomized clinical trial, we evaluated the impact of preoperative immunonutrition on tumor infiltrative lymphocytes and neoangiogenesis in cancerous tissue in patien...

Endoglin (CD105), a receptor of the transforming growth factor-β superfamily, has been reported to identify functional long-term repopulating hematopoietic stem cells, and has been detected in certain subtypes of acute leukemias. Whether this receptor plays a functional role in leukemogenesis remains unknown. We identified endoglin expression on the majority of blasts from patients with acute m...

Recent research has confirmed the presence of Mesenchymal stem cell (MSC)-like progenitors (MPC) in both normal and osteoarthritic cartilage. However, there is only limited information concerning how MPC markers are expressed with osteoarthritis (OA) progression. The purpose of this study was to compare the prevalence of various MPC markers in different OA grades. Human osteoarthritic tibial pl...

Angiogenesis in the peritumor tissue of glioblastoma (GBM) is still an open field of research. This study investigates neovascularization in the tumor surrounding areas by examining CD105 and nestin expression along with microvessel density (MVD) with the aim of establishing their possible prognostic significance. Angiogenesis was also confirmed by investigating, in vessel walls, the presence o...

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...

Mesenchymal stem cells are being the focus of connective tissue technology and regenerative medicine, presenting a good choice cell source for improving old and well recognized techniques of cartilage defect repair. For instance, the autologous chondrocyte transplantation using new concepts of regenerative medicine. The present study investigated the risk of xenogenicity of human synovial membr...

Introduction Identification and purification of mesenchymal stem cells (MSCs) expanded in culture for therapeutic use is crucial improved yield optimal results. Fibroblasts are the most common cell type connective tissue commonly found as contaminants MSC cultures, affecting potentially causing tumor formation after transplantation. In current study, we wished to identify surface markers that c...

BACKGROUND & OBJECTIVES Breast cancer is the second most common malignancy in Indian women. Among the members of the steroid receptor superfamily the role of estrogen and progesterone receptors (ER and PR) is well established in breast cancer in predicting the prognosis and management of therapy, however, little is known about the clinical significance of androgen receptor (AR) in breast carcin...
