Abstract: A column-based device and method for retrieving cells of interest were enclosed. The said device comprises a column comprising (i) an inner wall defining an inner chamber with inlet and outlet openings, (ii) a perforated plug disposed adjacent to the outlet opening, (iii) a sleeve insert with a channel and disposed within the chamber and adjacent to the perforated plug, and (iv) a filtering means housed within sleeve insert sandwiched between two sealing means. In particular, Tumor-derived endothelial cell clusters (TECCs) as characterized multiple nuclei, expression of endothelial markers (PECAM1, VWF and CDH5), and non-expression of leukocyte, megakaryocyte and platelets markers, may be retrieved using the disclosed device.

Abstract: The present invention relates to cell-based methods for determining the biological activity of defibrotide. In particular, the invention provides a method for assessing the potency of defibrotide by assessing the viability of mammalian cells in the presence of at least one cytotoxic agent and one or more concentrations of defibrotide. Such methods are particularly useful for standardizing pharmaceutical compositions comprising defibrotide.

Abstract: The present disclosure relates to an in-vitro method for identifying and analyzing ion channels and/or water channels and/or receptors of signal transduction, in which a three-dimensional sweat gland equivalent having from about 500 to about 500,000 sweat gland cells and a diameter of from about 100 to about 6,000 μm is firstly provided and then any ion channels and/or water channels and/or receptors of signal transduction present in this equivalent are infected and analysed. In a further method step c) the influence of test substances on the proteins identified previously in step b) is examined. Since the three-dimensional sweat gland equivalents used in step a) comprise differently differentiated cells and portray the in-vivo situation well, the measurement data obtained with the in-vitro method as contemplated herein can be transferred well to the in-vivo situation.

Abstract: Inflammatory cell recruitment to local sites of tissue injury and/or infection is controlled by many signaling processes influencing cell-to-cell interactions between vascular endothelial cells (EC) in post-capillary venules and circulating leukocytes. Here we report that the ATP-release channel Pannexin1 (Panx1) opens downstream of EC activation by tumor necrosis factor α (TNF α). This process involves activation of Type 1 TNF receptors, recruitment of Src Family Kinases (SFK), and SFK-dependent phosphorylation of Panx1. We report a previously unidentified role for Panx1 channels in promoting leukocyte adhesion and emigration through the venous wall during acute systemic inflammation. The present application further discloses that Panx IL2 peptide consisting of amino acid sequence KYPIVEQYLKYGRKKQRR (SEQ ID NO: 3) or 10Panx1 peptide consisting of amino acid sequence WRQAAFVDSY (SEQ ID NO: 8) are inhibitors of leukocyte adhesion.

Abstract: A method and device are disclosed for inducing mechanical stress in a cellular sample to evaluate mechanotransduction in the cellular sample. In one embodiment, the mechanical stress is induced by generating a microcavitation bubble in the cellular sample using a pulsed energy. The microcavitation bubble creates a microtsunami, which provides a transient, impulsive mechanical stress on the cellular sample, forming a gradient of effects at distances away from the microcavitation bubble.
