AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Human neural progenitor cells (hNPCs) have been proposed as a potential source of cells for ex vivo gene therapy. In this pilot study, three 5-year-old female cynomolgus monkeys received a single intracarotid infusion of MPTP, followed 1 week later by MRI- ...
Recombinant proteins are gaining in importance for therapeutic applications. The proteins are expressed in stable cell lines, within which recombinant DNA has incorporated into the host cells genome. Identification and isolation of extremely high producers ...
Angiogenic tumor vessels are promising targets for the activity and the selective delivery of cancer therapeutics. The bone marrow contributes different cell types to the tumor stroma, including hematopoietic cells and, as recently suggested, vascular endo ...
Adeno-associated virus (AAV) is a small non-enveloped virus and as a member of the parvovirus family, it contains a single stranded DNA genome. AAV's life cycle in vitro is strongly dependent not only on cellular factors but also on helper functions provid ...
Allogeneic cells are the most attractive source for cell transplantation, as the use of xenogeneic cells is hampered by safety concerns and the use of autologous cells involves practical difficulties. The immune rejection of allogeneic cells can be overcom ...
Recently, using HIV-1-derived lentivectors, we obtained efficient transduction of primary human B lymphocytes cocultured with murine EL-4 B5 thymoma cells, but not of isolated B cells activated by CD40 ligation. Coculture with a cell line is problematic fo ...
Exposure to human serum induces the lysis of xenogeneic cells through natural antibodies and complement activation. The carbohydrate Galactose-alpha1,3-Galactose (Gal-alpha1,3-Gal) epitope, has been shown to be the principal antigenic determinant on target ...
Human neural progenitor cells (hNPC) hold great potential as an ex vivo system for delivery of therapeutic proteins to the central nervous system. When cultured as aggregates, termed neurospheres, hNPC are capable of significant in vitro expansion. In the ...
We have developed a novel method called Calfection for gene delivery to and protein expression from suspension-cultivated mammalian cells. Plasmid DNA was simply diluted into a calcium chloride solution and then added to the cell culture for transfection. ...
Transient transfection allows for fast production of recombinant proteins. However, the current bottlenecks in transient transfection are low titers and low specific productivity compared to stable cell lines. Here, we report an improved transient transfec ...
