III Kardiologie und Kreislauferkrankungen So far, platelets were regarded static cells without further movement once they were adherent to fibrinogen or other extracellular matrices.

Migration of adherent platelets has not been discussed by the scientific audience so far. Methods and Results: 2-dimensional Verkalkungen in der Prostata diffus of platelets revealed that fibrinogen-adherent platelets synthesize or modify multiple proteins.

Most of these proteins include cytoskeletal proteins and proteins of the migration apparatus. We concluded that adherent platelets might be able to migrate on the surface of an extracellular matrix or endothelium. To demonstrate platelet migration we exposed fibrinogen-coated coverslips with adherent platelets to continuous flow under high shear rates as in the arterial vascular system.

All non-adherent platelets were removed from the experiment. Under continuous flow we observed shear stress induced mechanotaxis of human platelets some of which started to actively migrate along the direction of flow. Migrating platelets were still tightly adherent to the extracellular matrix and would have otherwise been swept away by the continuous flow. We found, that these migrating platelets underwent cytoskeletal rearrangement and formed pseudopodia.

We created a chemokine source constantly releasing chemokines and thereby generating a gradient. Platelets were actively migrating for several hours in this in-vitro setting. During migration platelets polarized and formed pseudopodia with modification of several proteins of the migratory aparatus under SDF1 exposure. When the SDF-1 source was removed, platelets migrated without a specific direction. We are currently performing inhibitory experiments on different levels of cell signalling to characterize the migratory apparatus of platelets.

We apply immunofluorescence, Western-Blot, 2-dimensional gel electrophoresis and mass spectrometry to differentiate the migratory apparatus of migrating cells. Conclusion: Platelets that adhere to fibrinogen are not irreversibly fixed on matrix surface. They are able to move into a specific direction guided by shear stress induced mechanotaxis or directed along a chemokine gradient.

By these mechanisms, platelets might be able to migrate into a platelet clot to further stabilize the hemostatic plug. Moreover, platelet migration may be a physiological mechanism to precisely cover denuded vascular lesions and further play a role in Verkalkungen in der Prostata diffus recruitment of platelets to the site Verkalkungen in der Prostata diffus vascular lesions or inflammation. Verkalkungen in der Prostata diffus Comparing groups according to genotype for each gene separately revealed a significantly greater reduction of body weight and BMI in carriers of at least on mutant allele in CB1 as well Verkalkungen in der Prostata diffus a greater reduction in triglycerides Verkalkungen in der Prostata diffus resistin mutant allele carriers.

We furthermore investigated gene-to-gene interaction: adding FAAH mutant alleles to carriers of at least one mutant allele in CB1, or resistin significantly influenced triglycerides, total- or LDL- cholesterol levels respectively.

Discussion: Our results support the hypothesis of obesity as a complex Verkalkungen in der Prostata diffus disorder with several genes involved in the development of an obese phenotype and obesity related comorbidities. Schäffler1, P.

PS4 Renal tubular cells induce epithelial differentiation of human mesenchymal stem cells PS2 Influence of genetic variation in four obesity candidate genes on body mass index and metabolism J. Aberle1, P. Peitsmeyer1, N. Beck1, F. Beil1 Medizinische Klinik, Universitätsklinikum Hamburg-Eppendorf, Hamburg Objective: It is believed that is in most cases obesity derives from an obesogenic environment on the basis of a genetic predisposition.

A large number of genes and genetic variations have been associated with obesity. Baer1, H. Geiger1 1Medical Clinic, Nephrology, J. Goethe-University, Frankfurt Objective: In the kidney, mesenchymal-epithelial interactions play a pivotal role in tubular cell morphogenesis and organ integrity.

During renal repair similar mechanisms may regulate cellular re-organisation and differentiation. Human mesenchymal stem cells MSC and renal tubular Verkalkungen in der Prostata diffus cells TEC are a specific in vitro system to analyse these interactions and differentiation mechanisms. Methods: MSC were isolated from lipoaspirates. TEC were separated from kidney sections from nephrectomies. Proliferation was measured by a fluorimetric assay and by MTT assay after days. Cellular differentiation of MSC was assessed by microscopic assessment morphologyWestern blotting cytokeratin 18and flow cytometric analysis CD Results: MSC morphology became more like an epithelial monolayer.

Similiarly, proliferation was induced short time effect, d incubation. When MSC were cultured in the presence of CM for 12 days long time effectdifferentiation was promoted as seen by a change in cellular morphology and the de novo expression of cytokeratin 18 as a marker of the epithelial lineage.

On the other hand, CD90 expression was diminished, but not totally discontinued. Conclusions: The study clearly demonstrates that secreted factors of TEC induce signal transduction, proliferation, and differentiation of mesenchymal stem cells towards the epithelial lineage. These mesenchymal-epithelial interactions may play an important role during renal repair mechanisms — either in normal tissue regeneration or after mesenchymal stem cell Verkalkungen in der Prostata diffus.

Da durch die Promotormutationen sowohl Bindungsstellen für Transkriptionsfaktoren zerstört werden, aber auch gleichzeitig neue entstehen, muss durch Messung des Verkalkungen in der Prostata diffus IL in den Patienten geklärt werden, wie sich diese Polymorphismen auf die IL Spiegel auswirken und ob eine genetisch bedingte erhöhte IL Produktion protektiv oder schädlich für die Transplantatniere ist.

Knedla1, Chr. Tennie1, I. Tarner1, H. Stürz2, J. Steinmeyer3, S. Gay4, U. Müller-Ladner1, E. Alternativ wurde zunächst Knorpel implantiert, 14 Tage später RASF intravenös ivsubkutan sc oder intraperitoneal ip injiziert.

Sie invadieren diesen unabhängig von der Art der Applikation. Am murinen Ohrknorpel sowie im Gelenk konnten teilweise humane Zellen, jedoch noch keine Destruktion des Knorpels nachgewiesen werden. Da RASF sowohl nekrotischen als auch bovinen Knorpel invadieren, erfolgt die Knorpeldestruktion offensichtlich unabhängig von der Vitalität der Chondrozyten und dem Spezies-Hintergrund zu erfolgen.
