Extracellular vesicles (EVs), such as exosomes and microvesicles, are released by different cell types and participate in physiological and pathophysiological processes. EVs mediate intercellular communication as cell-derived extracellular signalling organelles that transmit specific information from their cell of origin to their target cells. As a result(More)
Hematopoietic stem and progenitor cells (HSPCs) can self-renew and create committed progenitors, a process supposed to involve asymmetric cell divisions (ACDs). Previously, we had linked the kinetics of CD133 expression with ACDs but failed to detect asymmetric segregation of classical CD133 epitopes on fixed, mitotic HSPCs. Now, by using a novel anti-CD133(More)
PURPOSE Due to their minimal-invasive yet potentially current character circulating tumor cells (CTC) might be useful as a "liquid biopsy" in solid tumors. However, successful application in metastatic renal cell carcinoma (mRCC) has been very limited so far. High plasticity and heterogeneity of CTC morphology challenges currently available enrichment and(More)
Somatic stem cells are rare cells with unique properties residing in many organs and tissues. They are undifferentiated cells responsible for tissue regeneration and homeostasis, and contain both the capacity to self-renew in order to maintain their stem cell potential and to differentiate towards tissue-specific, specialized cells. However, the knowledge(More)
The increasing incidence of acyclovir (ACV) and multidrug-resistant strains in patients with corneal HSV-1 infections leading to Herpetic Stromal Keratitis (HSK) is a major health problem in industrialized countries and often results in blindness. To overcome this obstacle, we have previously developed an HSV-gB-specific monoclonal antibody (mAb 2c) that(More)
Via different committed progenitors, hematopoietic stem cells produce all mature blood cells. The classical model of hematopoiesis predicts multiple binary bifurcations, the first of it resulting in the separation of lymphoid and myeloid cell lineages. Combining complex flow cytometric analyses, fluorescent cell sorting and functional single cell analyses,(More)
Widespread metastasis is the leading course of death in many types of cancer, including malignant melanoma. The process of metastasis can be divided into a number of complex cell biological events, collectively termed the "invasion-metastasis cascade." Previous reports have characterized the capability of anchorage-independent growth of cancer cells in(More)
Heart and vascular endothelial cells from human pluripotent stem cells are of interest for applications in cell therapy and cardiovascular disease. Differentiation protocols are now sufficiently refined that production of cardiomyocytes, endothelial-and smooth muscle cells is fairly efficient and reproducible. Genetically marked hESCs have been produced in(More)
