  • Publication number: 20250019656
    Abstract: The present disclosure provides distinct therapeutic populations of cells that form a pharmaceutical composition useful in hematopoietic stem/progenitor cell transplant. For example, the present disclosure provides a therapeutic population of cells, comprising an enriched population of hematopoietic stem/progenitor cells, memory T cells, regulatory T cells, and wherein the population of cells is depleted of naïve conventional ??-T cells. The present disclosure further provides methods of treatment using the therapeutic population of cells. In other embodiments, the present disclosure provides methods of producing a therapeutic population of cells.

  • Publication number: 20240408198
    Abstract: Embodiments of the disclosure provide compositions, kits, and methods for allogeneic hematopoietic cell transplantation (alloHCT) to patients. In an embodiment, a therapeutic composition for alloHCT includes at least first and second populations of isolated CD45+ cells (ICC). At least a portion of the CD45+ cells in the first population may have an antibody bound to a marker on the cell surface which is used to separate CD34+ cells from a mixture of nucleated cells (MNC) from donor or invitro produced blood. The MNC may comprise various cell types in various amounts, for example, about 70% CD34+ cells, less than about 5% CD3+ cells and less about 20% granulocytes. The ICC's in the second population include regulatory T cells which are typically at least about 50% of the population. Embodiments of the disclosure are particularly useful for treatment of hematologic cancers (e.g., leukemia, lymphoma), sickle cell anemia, GVHD, autoimmune and other diseases.

  • Patent number: 10934355
    Abstract: Aspects of the present disclosure include methods of treating a subject to reduce adhesion formation, the method comprising administering to a subject in need of thereof an agent that that targets adhesion-formation by injured mesothelial cells. The agent can act at a variety of checkpoints in the development of adhesions by injured mesothelial cells, including: targeting the injured mesothelial cells for destruction, recruiting inflammatory macrophages to the site of adhesion, preventing neutrophil recruitment to the site of adhesion, and/or inhibiting the expression or activity of a gene product whose expression is induced in the injured mesothelial cells. Compositions and kits for performing the methods are also provided.
