Small-diameter vascular grafts currently in use have limitations, including restricted availability, requirements for anticoagulant therapy under specific circumstances, neoin-timal hyperplasia, and aneurysm formation. This review provides an overview of the history and recent studies in the field of small-diameter vascular grafts, including arterial and(More)
One of the most promising approaches in tissue engineering is the application of 3D scaffolds, which provide cell support and guidance in the initial tissue formation stage. The porosity of the scaffold and internal pore organization influence cell migration and play a major role in its biodegradation dynamics, nutrient diffusion and mechanical stability.(More)
It must be assumed that current petri dish primary hepatocyte culture models do not supply sufficient amounts of oxygen and thus cause anaerobic metabolism of the cells. This is contrary to the physiologic state of the cells. In vivo the liver is a highly vascularized organ with a rather high blood flow rate of a mixture of arterial and venous blood. The(More)
INTRODUCTION Myocardial infarction followed by heart failure represents one of the major causes of morbidity and mortality, particularly in industrialized countries. Engineering and subsequent transplantation of contractile artificial myocardial tissue and, consequently, the replacement of ischemic and infarcted areas of the heart provides a potential(More)
BACKGROUND Bleeding diathesis after aortic valve operation and ascending aorta replacement (AV-AA) is managed with fresh-frozen plasma (FFP) and platelet concentrates. The aim was to compare haemostatic effects of conventional transfusion management and FIBTEM (thromboelastometry test)-guided fibrinogen concentrate administration. METHODS A blood products(More)

BACKGROUND The risk of interspecies transmission of retroviruses during xenotransplantation is suggested by reports of pig endogenous retrovirus (PERV) released from porcine cell lines productively infecting human cell lines in vitro and of infectious PERV being released from pig peripheral blood mononuclear cells after mitogenic stimulation. Endothelial(More)
We investigated the gene expression of the nuclear transcription factors c/EBPalpha, GATA-2, and the silencer Oct-1 in conjunction with the gene expression of all major cytochrome P450 genes and of eNOS in cultures of endothelial cells of the rat. The purity of cultured endothelial cells was also confirmed by flow cytometry measurements of PECAM-1, a(More)
To harness the potential of human pluripotent stem cells (hPSCs), an abundant supply of their progenies is required. Here, hPSC expansion as matrix-independent aggregates in suspension culture was combined with cardiomyogenic differentiation using chemical Wnt pathway modulators. A multiwell screen was scaled up to stirred Erlenmeyer flasks and subsequently(More)
BACKGROUND Cold flush and static cold storage is the standard preservation technique for donor lungs before transplantations. Several research groups have assessed normothermic perfusion of donor lungs but all devices investigated were non-portable. We report first-in-man experience of the portable Organ Care System (OCS) Lung device for concomitant(More)
OBJECTIVES Understanding patients' perceptions and responses to immunosuppression-related symptom experiences following solid organ transplantation increases the likelihood that interventions can be designed to support long-term graft survival. METHODS This review summarizes and integrates evidence on transplant patients' symptom experiences related to(More)
