26. Studies on myeloid differentiation: cytokine influence and identification of a novel marker gene
Sammanfattning : Hematopoiesis is a highly complex process by which a range of specialized blood cells are generated from a small pool of multipotent stem cells in the bone marrow. The survival, proliferation, and differentiation of hematopoietic stem cells are tightly regulated by both soluble and membrane-bound cytokines produced within the bone marrow microenvironment.

27. Characterization of human myeloid progenitors and their differentiation
Sammanfattning : All hematopoietic cells are derived from the hematopoietic stem cells (HSCs) in a continuous and dynamic process, regulated by a network of transcription factors in different combinations and extrinsic signals from growth factors (GFs) and other factors in the microenvironment. In the initial stages of hematopoiesis HSCs differentiate to progenitor cells with gradually more restricted lineage potential and according to the most accepted model the first restriction in developmental potential results in commitment to either the lymphoid or the myeloid branch, in the latter followed by commitment to the neutrophil/monocyte and erythrocyte/megakaryocyte lineages.

28. Lineage commitment to a T
Sammanfattning : he hematopoietic development is a highly dynamic but tightly regulated process. The flexibility to produce blood cells through more than one route will allow the blood system to respond rapidly in stress situations such as infections. LÄS MER
29. Consequences of Shb Deficiency on Hematopoietic Cell Function
Sammanfattning : The adaptor protein Shb has been implicated in the signaling of several tyrosine kinase receptors and previous studies have suggested a role for Shb in the signal transduction of T cells. Shb associates with the T cell receptor (TCR) and partakes in the signal propagation of activated T lymphocytes. LÄS MER
30. The Wilms' tumor gene 1 (WT1) and leukemia -new insights and further complexity
Sammanfattning : The Wilms tumor gene 1 (WT1) encodes a zinc-finger containing transcription factor which is highly expressed in immature hematopoietic progenitor cells. A high expression of WT1 and the presence of somatic mutations in acute leukemia indicate a role for WT1 in the pathogenesis of leukemia. LÄS MER
