Abstract: The present technology provides methods and compositions for the treatment of inflammatory and/or tissue damage conditions. In particular, the use of Smad7 compositions delivered locally or systemically to a site of inflammation and/or tissue damage is described. Other specific embodiments concern treatment or prevention of side effects caused by radiation and/or chemotherapy, including but not limited to oral and gastric mucositis. Also provided are codon-optimized nucleic acids encoding for Smad7 fusion proteins.

Abstract: Disclosed are methods for manipulating and expanding stem cell populations, including adult stem cells, the cells produced by such methods, and various protein constructs related thereto.

Abstract: The present disclosure relates to the production of red blood cells from hematopoietic stem cells, by differentiating such cells in the presence of a protein that induces cell survival and proliferation.

Abstract: This invention generally relates to methods for the production of antibody producing cells and antibodies in protooncogene expressing animals. The invention also relates to methods for the efficient production of antibodies specific for antigens that are normally subject to immunological constraints such as self tolerance. The invention further relates to the production of antibody producing cells and antibodies without the need for the conventional fusing of antibody producing B cells with a myeloma fusion partner.

Abstract: The present invention provides methods for the generation of xenochimaeric animals; for example, xenochimaeric mice, comprising bone marrow progenitor cells and tumors from a heterologous animal. In some aspects, the invention provides xenochimaeric mice bearing humanized bone marrow and human tumors. Such animals are a model system for the study of human tumor stroma, for drug discovery, and for the treatment of human cancers.

Abstract: Disclosed are non-human animal models, and preferably, rodent models, and more preferably, mouse models, of B-cell Non-Hodgkin's Lymphoma (NHL). In particular, the present invention provides animal models of B cell NHL including, B cell chronic lymphocytic leukemia/lymphoma (B-CLL), Burkitt's lymphoma (BL), Follicular-like lymphoma (FLL) and Diffuse large B-cell lymphoma (DLBCL), as well as various methods for producing these non-human animal models. These animal models, as well as cell lines produced from or derived from these models, are useful tools for a variety of methods, including, but not limited to, preclinical testing of drug candidates, and particularly drug candidates that are specific for human proteins, and any research, development, pharmaceutical, or clinical purpose, including but not limited to, the identification, development, and/or testing of drugs (therapeutics, prophylactics, etc.
