  • Patent number: 9958446
    Abstract: Disclosed is a therapeutic method including administering a TIM-3 antibody or its TIM-3 binding fragment to a subject who is suspected to be suffering from blood tumor and in whom TIM-3 has been expressed in a Lin(?)CD34(+)CD38(?) cell fraction of bone marrow or peripheral blood or a subject who has been received any treatment for blood tumor. Conceived diseases include those diseases which can be treated through the binding or targeting of the TIM-3 antibody or its TIM-3 binding fragment to blood tumor cells (AML cells, CML cells, MDS cells, ALL cells, CLL cells, multiple myeloma cells, etc.), helper T cell (e.g., Th1 cells, Th17 cells), and antigen-presenting cells (e.g., dendritic cells, monocytes, macrophages, and cells resembling to the aforementioned cells (hepatic stellate cells, osteoclasts, microglial cells, intraepidermal macrophages, dust cells (alveolar macrophages), etc)).

  • Patent number: 7618654
    Abstract: A substantially enriched mammalian hematopoietic cell subpopulation is provided, which is characterized by progenitor cell activity for myeloid lineages, but lacking the potential to differentiate into lymphoid lineages. This population is further divided into specific myeloid progenitor subsets, including a common myeloid progenitor cells (CMP), megakaryocyte/erythroid progenitor cells (MEP) and granulocyte/monocyte lineage progenitor (GMP). Methods are provided for the isolation and culture of these subpopulations. The CMP population gives rise to all myeloid lineages, and can give rise to the two additional and isolatable progenitor populations that are exclusively committed to either the erythroid/megakaryocytic or myelomonocytic lineages. T?? ???? ????????? ????o?? ????o???????? ???? ??????????o????? T??-1; ???I?-7 P?, in conjunction with other markers expressed on lineage committed cells.

  • Patent number: 7297329
    Abstract: A substantially enriched mammalian hematopoietic cell subpopulation is provided, which is characterized by progenitor cell activity for lymphoid lineages, but lacking the potential to differentiate into myeloid and erythroid lineages. Methods are provided for the isolation and culture of this common lymphoid progenitor cell (CLP). The cell enrichment methods employ reagents that specifically recognize CDw127 (IL-7 receptor ?); CD117 (c-kit) protein, in conjunction with other markers expressed on lineage committed cells. The murine cells are also characterized as expressing low levels of sca-1 (Ly-6E and Ly-6A). The CLPs are predominantly cycling, blast cells. These cells give rise to B cells, T cells and natural killer cells, as evidenced by their growth and differentiation in vitro and in vivo.
