Publication number: 20140273096Abstract: The present invention relates to nucleic acid sequences coding for modified coagulation factors, preferably coagulation factor VIII, and their derivatives; recombinant expression vectors containing such nucleic acid sequences; host cells transformed with such recombinant expression vectors; and recombinant polypeptides and derivatives coded for by said nucleic acid sequences, whereby said recombinant polypeptides and derivatives have biological activities and prolonged in vivo half-lives compared to the unmodified wild-type proteins. The invention also relates to corresponding sequences that result in improved in vitro stability. The present invention further relates to processes for the manufacture of such recombinant proteins and their derivatives. The invention also relates to a transfer vector for use in human gene therapy, which comprises such nucleic acid sequences.Type: ApplicationFiled: April 9, 2014Publication date: September 18, 2014Applicant: CSL Behring GmbHInventors: Stefan SCHULTE, Thomas WEIMER, Hubert METZNER

Publication number: 20140256036Abstract: A model of tissue is produced by steps comprising seeding cells at a selected concentration on a support to form a cell spot, incubating the cells to allow the cells to partially attach, rinsing the cells to remove any cells that have not partially attached, adding culture medium to enable the cells to proliferate at a periphery of the cell spot and to differentiate toward a center of the cell spot, and further incubating the cells to form the tissue. The cells may be C2C12 cells or other subclones of the C2 cell line, H9c2(2-1) cells, L6 cells, L8 cells, QM7 cells, Sol8 cells, G-7 cells, G-8 cells, other myoblast cells, cells from other tissues, or stem cells. The selected concentration is in a range from about 1×105 cells/ml to about 1×106 cells/ml.Type: ApplicationFiled: May 20, 2014Publication date: September 11, 2014Inventors: Michele L.
