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 &agr;); 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： This invention provides a reagent capable of binding to T cells and having specificity for a unique sequence within the variable region of the .beta. chain of the T cell receptor, the presence of increased number of T cells carrying the unique sequence relative to the number of T cells carrying the sequence present in a normal subject being associated with a specific disease. Specific diseases such as human cancers, e.g. lymphomas; autoimmune diseases, e.g. rheumatoid arthritis; Alzheimer's disease; infectious diseases, e.g. those caused by bacteria, yeast or parasite; or allergies, may be diagnosed as follows. A suitable sample containing T cells is obtained from a subject. The sample is contacted under appropriate conditions with such a reagent. If the subject's cells contain the unique sequence, a detectable complex is formed between the reagent and T cells which contain the sequence. By quantitatively determining the number of T cells containing the sequence present in the complex formed and comparing this number with the number of T cells carrying the sequence determined for a normal subject, the disease with which the unique sequence is associated may be diagnosed. Similar reagents and methods may also be used to detect organ transplant rejection.

摘要： 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.

摘要： Composition and methods are provided for the prospective enrichment of human cardiovascular progenitor cells, which can be differentiated into cardiomyocytes, from in vitro cultures of stem cells. The stem cells are cultured in conditions permissive for differentiation into cardiovascular progenitor cells, and cardiovascular progenitor cells are sorted for expression of one or more of the markers ROR2, CD13, KDR and PDGFαR, where the progenitor cells positively express these markers. Highly enriched populations of cardiomyocyte lineage cells can be obtained.

摘要： Isolated populations of leukemic stem cells are provided. The cells are useful for experimental evaluation, and as a source of lineage and cell specific products, and as targets for the discovery of factors or molecules that can affect them. Detection of leukemic stem cells is useful in predicting disease progression, relapse, and development of drug resistance. Proliferation of LSC may be inhibited through interfering with activation of the β-catenin pathway. Methods are provided for the clinical staging of pre-leukemia and leukemias by differential analysis of hematologic samples for the distribution of one or more hematopoietic stem or progenitor cell subsets.
