The human AC133 antigen and mouse prominin are structurally related plasma membrane proteins. However, their tissue distribution is distinct, with the AC133 antigen being found on hematopoietic stem and progenitor cells and prominin on various epithelial cells. To determine whether the human AC133 antigen and mouse prominin are orthologues or distinct(More)
Haemophilus influenzae (Hi), a commensal of the human respiratory mucosa, is an important cause of localized and systemic infections. We show that distinct strains belonging to typable (THi) and non-typable (NTHi) H. influenzae target human carcinoembryonic antigens (the membrane associated CEA family of cell adhesion molecules, are now termed CEACAMs). All(More)
AIMS To provide systematic assessment of the safety and efficacy of autologous bone marrow-derived stem cell (BMSC) transplantation in acute myocardial infarction (AMI) based on clinical evidence. METHODS AND RESULTS The search strategy included MEDLINE, EMBASE, the Cochrane Library, and Current Controlled Trials Register through to August 2007 for(More)
Malarial anemia is a global public health problem and is characterized by a low reticulocyte response in the presence of life-threatening hemolysis. Although cytokines, in particular tumor necrosis factor-alpha (TNF-alpha), can suppress erythropoiesis, the grossly abnormal bone marrow morphology indicates that other factors may contribute to ineffective(More)
Here we describe a procedure for cloning pigs by the use of in vitro culture systems. Four healthy male piglets from two litters were born following nuclear transfer of cultured somatic cells and subsequent embryo transfer. The initiation of five additional pregnancies demonstrates the reproducibility of this procedure. Its important features include(More)
Using COS (African green monkey kidney) cells transfected with cDNAs encoding human cell surface molecules, we have identified human cellular receptors for meningococcal virulence-associated Opa proteins, which are expressed by the majority of disease and carrier isolates. These receptors belong to the immunoglobulin superfamily of adhesion molecules and(More)
Opa protein-expressing pathogenic neisseriae interact with CD66a-transfected COS (African green monkey kidney) and CHO (Chinese hamster ovary) cells. CD66a (BGP) is a member of carcinoembryonic antigen (CEA, CD66) family. The interactions occur at the N-terminal domain of CD66a, a region that is highly conserved between members of the CEA subgroup of the(More)
BACKGROUND AND OBJECTIVES Mesenchymal stem/progenitor cells (MSCs) are multipotent progenitors that differentiate into such lineages as bone, fat, cartilage and stromal cells that support haemopoiesis. Bone marrow MSCs can also contribute to cardiac repair, although the mechanism for this is unclear. Here, we examine the potential of MSCs from different(More)
BACKGROUND Stem cell therapy offers a promising approach to the regeneration of damaged vascular and cardiac tissue after myocardial infarction (MI). This has resulted in multiple randomised controlled trials (RCTs) worldwide. OBJECTIVES To critically evaluate evidence from RCTs on the effectiveness of adult bone marrow-derived stem cells (BMSC) to treat(More)
