The T lineage glycoprotein CD6 is generally considered to be a costimulator of T-cell activation. Here, we demonstrate that CD6 significantly reduces early and late T-cell responses upon superantigen stimulation or TCR triggering by Abs. Measuring calcium mobilization in single cells responding to superantigen, we found that human T cells expressing rat CD6 react significantly less well compare...
Metastatic colorectal cancer remains a serious health concern with poor patient survival. Although 5-Fluorouracil (5-FU) or 5-FU plus oxaliplatin (FOLFOX) is the standard therapy for colorectal cancer, it has met with limited success. Recurrence of the tumor after chemotherapy could partly be explained by the enrichment of the chemo-resistant sub-population of cancer stem cells (CSCs) that poss...
about 3 decades ago cd6 identified as one of the first antigens expresses on the majority of t cells and a subset of b cells. cd6 regulates cellular adhesion migration across the endothelial and epithelial cells. in recent years researches indicate its role in pathogenesis of autoimmune diseases. many researches have been done in recent years to block cd6 by cd6 mono clonal antibodies, ior-t1 a...
Mesenchymal stem cells (MSCs) provide a novel option in cellular therapy and tissue engineering. Recent studies indicated that it is possible to obtain MSCs from peripheral blood by attachment ability to plastic surface. To evaluate adherent cells derived from peripheral blood, their expression profile and surface markers were investigated. The results of RT-PCR indicated that these cells expre...
A portion of osteoarthritis (OA) patients with total knee arthroplasty (TKA) had monocondylar destruction in medial femoral condyle, but healthy-appearant cartilage in lateral side. However, there is limited information concerning functional differences of cartilage derived mesenchymal stem cell (CMSC) between these two locations in the same donor and its possible role in the pathogenesis of OA...
BACKGROUND & AIMS Tumor-initiating cells are a subset of tumor cells with the ability to form new tumors; however, they account for less than 0.001% of the cells in colorectal or other types of tumors. Mesenchymal stem cells (MSCs) integrate into the colorectal tumor stroma; we investigated their involvement in tumor initiation. METHODS Human colorectal cancer cells, MSCs, and a mixture of bo...
