摘要:
Methods are provided for treatment of lung cancers, particularly small cell lung cancer with targeted therapy, which optionally includes an agent that selectively blocks CD47 binding to SIRPα.
摘要:
Methods are provided to manipulate phagocytosis of cells, including hematopoietic cells, e.g. circulating hematopoietic cells, bone marrow cells, etc.; and solid tumor cells. In some embodiments of the invention the circulating cells are hematopoietic stem cells, or hematopoietic progenitor cells, particularly in a transplantation context, where protection from phagocytosis is desirable. In other embodiments the circulating cells are leukemia cells, particularly acute myeloid leukemia (AML), where increased phagocytosis is desirable.
摘要:
Methods are provided for treatment of lung cancers, particularly small cell lung cancer with targeted therapy. The therapy is targeted at one or more cell-surface antigens, including CD24, CD166, CD56, CD326, CD298, CD29, CD63, CD9, CD164, CD99, CD46, CD59, CD57, CD165, and EpCAM, which optionally includes an agent that selectively blocks CD47 binding to SIRPa.
摘要:
Markers of acute myeloid leukemia stem cells (AMLSC) are identified. The markers are differentially expressed in comparison with normal counterpart cells, and are useful as diagnostic and therapeutic targets.
摘要:
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. The cell enrichment methods employ reagents that specifically recognize CDw127 (IL-7 receptor α); CD117 (c-kit) protein, in conjunction with other markers expressed on lineage committed cells. These cells give rise to a variety of myeloid cells, including megakaryocytes, granulocytes, dendritic cells and erythroid cells, as evidenced by their growth and differentiation in vitro and in vivo.
摘要:
Reagents that block the extracellular activation of β-catenin are used to induce quiescence in normal stem cells, in order to reduce the killing of stem cells by anti-proliferative agents.
摘要:
A substantially enriched mammalian hematopoietic cell population is provided, which is characterized as a progenitor cell committed to the megakaryocyte lineage. Methods are provided for the isolation and culture of these cells. The cell enrichment methods employ reagents that specifically recognize CD9 and CD41, in conjunction with other markers expressed on lineage committed progenitor cells. These cells give rise exclusively to megakaryocytes and platelets, as evidenced by their growth and differentiation in vitro and in vivo.
