Stem cell research, Volume 6, Issue 3, 28 4 2011, Pages 206-214 Human mesenchymal stem cell-conditioned medium improves cardiac function following myocardial infarction. Timmers L, Lim SK, Hoefer IE, Arslan F, Lai RC, van Oorschot AA, Goumans MJ, Strijder C, Sze SK, Choo A, Piek JJ, Doevendans PA, Pasterkamp G, de Kleijn DP

Recent studies suggest that the therapeutic effects of stem cell transplantation following myocardial infarction (MI) are mediated by paracrine factors. One of the main goals in the treatment of ischemic heart disease is to stimulate vascular repair mechanisms. Here, we sought to explore the therapeutic angiogenic potential of mesenchymal stem cell (MSC) secretions. Human MSC secretions were collected as conditioned medium (MSC-CM) using a clinically compliant protocol. Based on proteomic and pa... Abstract

Molecular therapy : the journal of the American Society of Gene Therapy, Volume 19, Issue 7, 25 4 2011, Pages 1331-1341 Transcription factor rational design improves directed differentiation of human mesenchymal stem cells into skeletal myocytes. Gonçalves MA, Janssen JM, Nguyen QG, Athanasopoulos T, Hauschka SD, Dickson G, de Vries AA

There is great interest in transdifferentiating cells from one lineage into those of another and in dedifferentiating mature cells back into a stem/progenitor cell state by deploying naturally occurring transcription factors (TFs). Often, however, steering cellular differentiation pathways in a predictable and efficient manner remains challenging. Here, we investigated the principle of combining domains from different lineage-specific TFs to improve directed cellular differentiation. As proof-of... Abstract

PloS one, Volume 6, Issue 1, 24 4 2011, Pages e16118 A sensitive assay for virus discovery in respiratory clinical samples. de Vries M, Deijs M, Canuti M, van Schaik BD, Faria NR, van de Garde MD, Jachimowski LC, Jebbink MF, Jakobs M, Luyf AC, Coenjaerts FE, Claas EC, Molenkamp R, Koekkoek SM, Lammens C, Leus F, Goossens H, Ieven M, Baas F, van der Hoek L

In 5-40% of respiratory infections in children, the diagnostics remain negative, suggesting that the patients might be infected with a yet unknown pathogen. Virus discovery cDNA-AFLP (VIDISCA) is a virus discovery method based on recognition of restriction enzyme cleavage sites, ligation of adaptors and subsequent amplification by PCR. However, direct discovery of unknown pathogens in nasopharyngeal swabs is difficult due to the high concentration of ribosomal RNA (rRNA) that acts as competitor.... Abstract

Familial Mediterranean fever is an autosomal recessive disease characterized by recurrent self-limited attacks of fever accompanied by peritonitis, pleuritis, and arthritis. Approximately 5% of individuals with familial Mediterranean fever have been reported to have Henoch-Schonlein purpura and about 1% to have polyarteritis nodosa. A 7-year-old girl presenting with complaints of purpuric rash, abdominal pain, arthritis, hematuria, and proteinuria and having IgA depositions on renal biopsy was d... Abstract

New TB vaccines are urgently needed because of the apparent lack of effect of the BCG vaccine on rates of adult contagious pulmonary tuberculosis and the risk of disseminated BCG disease in immunocompromised individuals. Since BCG appears to protect children, the primary target for vaccine development is a booster vaccine for adults but such vaccines ideally need to be able to efficiently prime mycobacterially naïve individuals as well as boost individuals previously vaccinated with BCG and thos...

The pharmacogenomics journal, Volume 12, Issue 3, 18 3 2011, Pages 233-237 Differential effect of the rs4149056 variant in SLCO1B1 on myopathy associated with simvastatin and atorvastatin. Brunham LR, Lansberg PJ, Zhang L, Miao F, Carter C, Hovingh GK, Visscher H, Jukema JW, Stalenhoef AF, Ross CJ, Carleton BC, Kastelein JJ, Hayden MR

Statins reduce cardiovascular morbidity and mortality in appropriately selected patients. However, statin-associated myopathy is a significant risk associated with these agents. Recently, variation in the SLCO1B1 gene was reported to predict simvastatin-associated myopathy. The aim of this study was to replicate association of the rs4149056 variant in SLCO1B1 with severe statin-associated myopathy in a cohort of patients using a variety of statin medications and to investigate the association wi...

Cardiovascular research, Volume 90, Issue 2, 13 2 2011, Pages 295-304 Antiproliferative treatment of myofibroblasts prevents arrhythmias in vitro by limiting myofibroblast-induced depolarization. Askar SF, Ramkisoensing AA, Schalij MJ, Bingen BO, Swildens J, van der Laarse A, Atsma DE, de Vries AA, Ypey DL, Pijnappels DA

Aims: Cardiac fibrosis is associated with increased incidence of cardiac arrhythmias, but the underlying proarrhythmic mechanisms remain incompletely understood and antiarrhythmic therapies are still suboptimal. This study tests the hypothesis that myofibroblast (MFB) proliferation leads to tachyarrhythmias by altering the excitability of cardiomyocytes (CMCs) and that inhibition of MFB proliferation would thus lower the incidence of such arrhythmias. Methods and results: Endogenous MFBs in neon... Abstract

Aims: The risk of infective endocarditis (IE) in adults with congenital heart disease is known to be increased, yet empirical risk estimates are lacking. We sought to predict the occurrence of IE in patients with congenital heart disease at the transition from childhood into adulthood.

Intramyocardial bone marrow cell injection is currently being investigated as a new therapeutic option for the treatment of chronic myocardial ischemia. Experimental studies and early phase clinical trials established a favorable safety profile of this approach and suggested that bone marrow cell injection was associated with clinical and functional improvements. Recently, a randomized, double-blind, placebo-controlled trial demonstrated that intramyocardial bone marrow cell injection was associ... Abstract

European journal of surgical oncology : the journal of the European Society of Surgical Oncology and the British Association of Surgical Oncology, Volume 37, Issue 3, 6 1 2011, Pages 252-257 Intraoperative near-infrared fluorescence imaging of colorectal metastases targeting integrin α(v)β(3) expression in a syngeneic rat model. Hutteman M, Mieog JS, van der Vorst JR, Dijkstra J, Kuppen PJ, van der Laan AM, Tanke HJ, Kaijzel EL, Que I, van de Velde CJ, Löwik CW, Vahrmeijer AL

Aim: Near-infrared (NIR) fluorescence optical imaging is a promising technique to assess the extent of colorectal metastases during curative-intended surgery. However, NIR fluorescence imaging of liver metastases is highly challenging due to hepatic uptake and clearance of many fluorescent dyes. In the current study, the biodistribution and the ability to demarcate liver and peritoneal metastases were assessed during surgery in a syngeneic rat model of colorectal cancer using an integrin α(v)β(3...

Background: Mesenchymal stem cells (MSCs) are multipotent cells residing in the connective tissue of many organs and holding great potential for tissue repair. In culture, human MSCs (hMSCs) are capable of extensive proliferation without showing chromosomal aberrations. Large numbers of hMSCs can thus be acquired from small samples of easily obtainable tissues like fat and bone marrow. MSCs can contribute to regeneration indirectly by secretion of cytokines or directly by differentiation into sp... Abstract
