Patents by Inventor Mark C. Poznansky

Mark C. Poznansky has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7951364
    Abstract: This invention relates to methods and compositions for modulating movement of eukaryotic cells with migratory capacity. More specifically, the invention relates to methods and compositions for modulating movement of CaR receptor expressing cells of hematopoietic, neural, epithelial, endothelial, or mesenchymal origin, in a specific site in a subject. The foregoing are useful, inter alia, in the treatment of conditions characterized by a need to modulate migratory-cell movement associated with specific sites in a subject. Specific sites include sites of inflammation and modulation of migratory-cell movement is movement away from an agent source, or repulsion. The invention also relates to methods for manipulating hematopoeitic progenitor cells and related products.

  • Publication number: 20100266561
    Abstract: The present invention relates generally to systems and methods of enhancing recovery of function of injured tissue through administration of a composition comprising a relatively pure populations of B lymphocyte cells in a pharmaceutically acceptable carrier to the injured tissue. Kits are provided to aid in purification of B cells from heterogeneous mixtures of cells and administration of B cells to injured tissue.

  • Patent number: 7745578
    Abstract: This invention relates to compositions and methods that modulate the movement of cells with migratory capacity. More specifically, the invention relates to compositions and methods for promoting migratory movement, fugetaxis, of cells from a specific site in a subject. The foregoing are useful, inter alia, in the treatment of conditions characterized by a need to promote migratory cell movement away from specific sites in a subject. Specific sites include sites of inflammation, infection, an autoimmune reaction, a tumor and a transplanted organ or tissue.

  • Patent number: 7192769
    Abstract: The invention relates to a method for lymphoid tissue-specific cell production from hematopoietic progenitor cells in unique, three-dimensional culture devices, in the presence of antigen presenting cells and lymphoreticular stromal cells, and in the absence of exogenously added growth factors. The resulting lymphoid tissue-specific cells may be isolated at any sequential stage of differentiation and further expanded. The lymphoid tissue-specific cells also may be genetically altered at any stage of the process.
