Patent number: 8216342Abstract: A method for producing membranes which contain at least one solid layer on one side of a porous substrate by treating the side of the support, which is to be coated, with a synthetic solution that forms the solid layer. The inventive method is characterized in that the space located behind the side of the porous support, which is not to be coated, is filled with an inert fluid during the production of the solid layer on the porous support, “behind” being from the perspective of the support. The pressure and/or the temperature of the fluid is/are selected such that the synthetic solution is essentially prevented from entering in contact with the side of the porous support, which is not to be coated.Type: GrantFiled: January 13, 2005Date of Patent: July 10, 2012Assignee: BASF SEInventors: Stefan Bitterlich, Hartwig Voβ, Gunter Schuch, Armin Diefenbacher, Manfred Noack, Ronald Schäfer, Ingolf Voigt, Hannes Richter, Jürgen Caro

Patent number: 7666393Abstract: We have discovered that endothelial progenitor cells (EPC) are particularly suitable for use in a sensitive assay for antiangiogenic factors. We have found that EPC mobilization and differentiation is greatly inhibited by antiangiogenic factors as evidenced in vivo by VEGF inducing a massive mobilization of EPC into the blood circulation which effect is significantly inhibited by endostatin treatment, and, in vitro, human blood-derived EPC forming adherent colonies, which colonies, in the presence of angiogenic factors, give rise to differentiated EC, and which differentiation is disrupted and cell growth is inhibited in the presence of angiostatin and endostatin.Type: GrantFiled: May 9, 2002Date of Patent: February 23, 2010Assignee: Children's Medical Center CorporationInventors: Shay Soker, Anthony Atala, Gunter Schuch
