  • Patent number: 8168588
    Abstract: Pharmaceutical polypeptide compositions promote the survival of cardiac cells, recruit cardiac cells to the cardiac area, stimulate the differentiation of cardiac cells, stimulate the proliferation of cardiac cells, and promote the activity of cardiac cells, thereby treating cardiac conditions. Methods of providing these compositions to the cardiac area include catheterization and direct injection. In preferred embodiments, the compositions comprise one of more of the following growth factors: EGF, bFGF, cardiotrophin-1, thrombin, PDGF-BB, amphiregulin, epiregulin, HB-EGF, TGFalpha, betacellulin, heregulin alpha, NRG-1-beta1-HRG-beta1, FGF 9.

  • Publication number: 20110281302
    Abstract: The invention provides FGFR fusion proteins, methods of making them, and methods of using them to treat proliferative disorders, including cancers and disorders of angiogenesis. The FGFR fusion molecules can be made in CHO cells and may comprise deletion mutations in the extracellular domains of the FGFRs which improve their stability. These fusion proteins inhibit the growth and viability of cancer cells in vitro and in vivo. The combination of the relatively high affinity of these receptors for their ligand FGFs and the demonstrated ability of these decoy receptors to inhibit tumor growth is an indication of the clinical value of the compositions and methods provided herein.

  • Publication number: 20080147909
    Abstract: Machine-readable media, methods, apparatus and system are described. In some embodiments, a host platform may receive a first USB command from a client platform, wherein the first USB command notifies the host platform that a USB device is plugged into the client platform. The host platform may further create a virtual USB device as a virtualization of the USB device in response to the first USB command, and may establish a USB device driver in response to the creation of the virtual USB device. The USB device driver may control the USB device in the client platform.

  • Publication number: 20080112937
    Abstract: Aspects of the present invention relate to compositions and methods of reprogramming a somatic cell to give rise to an autologous embryonic stem cell. These methods involve providing a somatic cell of a donor subject, introducing the somatic cell into an embryo of a recipient subject to produce a chimeric embryo, allowing the chimeric embryo to develop further wherein the somatic cell will reprogram, and then selecting an autologous embryonic stem cell that has developed from the somatic cell. The methods and composition of producing pluripotent embryonic stem cells from a donor's own somatic cells invite the possibility of a number of therapeutic applications, including organ transplant and treatment of autoimmune diseases, cancer, and degenerative disorders such as diabetes, Alzheimer's, and Parkinson's.

  • Publication number: 20060035373
    Abstract: A stem cell library is created by genetically modifying stem cells with nucleic acids encoding polypeptides which can promote stem cell differentiation into specific cell types. Alternatively, the stem cell library is exposed to an externally added factor that promotes stem cell differentiation into a desired cell line, e.g., neuronal or muscle. The library is used to determine the effect of the encoded protein on the differentiation process. The library is also used to produce nucleic acids for insertion into embryonic stem cells to produce transfected embryonic stem cells. The nucleic acids are inserted into a locus that permits widespread expression of the encoded polypeptide in animals produced from blastocysts that incorporate the transfected cells. Non-human chimeric animals produced by combining blastocysts derived from animal models of human disease and embryonic stem cells transfected with molecules from the library provide an in vivo system for therapeutic design.
