Administration of in vitro expanded mesenchymal stromal cells (MSCs) represents a promising therapy for regenerative medicine and autoimmunity. Both mouse and human MSCs ameliorate autoimmune disease in syn-, allo- and xenogeneic settings. However, MSC preparations are heterogeneous which impairs their therapeutic efficacy and endorses variability between experiments. This heterogeneity has als...

CD105, a marker of endothelial cells, is abundantly expressed in tissues undergoing angiogenesis and is a receptor for transforming growth factorbeta. The pivotal role of CD105 in the vascular system was demonstrated by the severe vascular defects that occur in CD105-knockout mice, but the exact mechanisms for CD105 regulation of vascular development have not been fully elucidated. In light of ...

The present study aimed to investigate the feasibility of isolating adipose-derived stem cells (ADSCs) by selecting cells that express the surface receptor CD105. Surface antigen expression of the unsorted cells was undertaken using FACS analysis. Primary adipose-derived cells were isolated. The second passage cells were incubated with anti-CD105 magnetic beads, and separated using a magnetic s...

CD105, a receptor for TGF-b1 and -b-3 modulates TGF-b signaling by interacting with TGF-bRI and/or II. It is now emerging as a prime vascular target of antiangiogenetic cancer therapy. In the present study, we investigate the efficacy of CD105 in colorectal cancer models. We found decreases in tumor size and in the number of metastatic foci to lung in a xenograft cancer model in scid mouse that...

Background. The role of endoglin in the Dukes B rectal cancer is still unexplored. The aim of this study was to examine the expression of endoglin (CD105) in resected rectal cancer and to evaluate the relationship between microvessels density (MVD), clinicopathological factors, and survival rates. Methods. The study included 95 primary rectal adenocarcinomas, corresponding to 67 adjacent and 73...

Transforming growth factor beta (TGF-b) inhibits T cell activation and alters differentiation of naive T cells into effector cells. Although four main cell-surface proteins can interact with TGF-b, only the signaling receptors type I (TGF-bR type I) and type II (TGF-bR type II) have so far been described on T cells. The aim of the present study was to investigate the expression of the ancillary...

BACKGROUND The epithelial-mesenchymal transition (EMT) generates cells with properties of stem cells, if that happened, the stem cell should be with mesenchymal property. This study aimed to identify a group of cells with mesenchymal stem cell (MSC)-like characteristics in breast cancer bone metastatic cell line MDA-MB-231, moreover, the relevance between breast cancer stem cells and the EMT wa...

AIM To compare endoglin (CD105) and the pan-endothelial marker CD31 in the assessment of angiogenesis in glioblastoma and to evaluate their values in the prognosis of this malignancy. METHODS Forty-six cases of glioblastoma were included in this retrospective study. All cases were immunohistochemically stained for endoglin (CD105), CD31, vascular endothelial growth factor (VEGF), and MIB-1 (K...

AIM The expression pattern of endoglin (CD105) in hepatocellular carcinoma (HCC) has not been reported so far. We hypothesized that CD105 could differentially highlight a subset of microvessels in HCC, and intratumoral microvessel density (IMVD) by CD105 immunostaining (IMVD-CD105) could provide better prognostic information than IMVD by CD34 immunostaining (IMVD-CD34). METHODS Paraffin block...

The present study aimed to develop a quick and efficient method for purification of newborn endothelial cells from tumor tissues. Fresh tissues were separated from C57BL/6 mice bearing tumors derived from mouse lung cancer Lewis cells, fully minced and divided into two parts. One part was subjected to collagenase type I digestion with a vortex to form a single-cell suspension, while another par...
