Background: MSCs have been isolated from a variety of mammals by the plastic adherence method. However, this method can be problematic due to the unwanted growth of hematopoietic cells and non-MSCs. The potential of MSCs to differentiate along multiple lineages is the key to the identification of stem cell populations in the absence of molecular markers. In the present study, we describe a homo...
The ability of the many cell types within the adult blood system to be constantly replenished and renewed from hematopoietic stem cells is an interesting problem in development and differentiation and has led to questions concerning how, when and where these stem cells for the adult hematopoietic system are generated within the embryo. During embryonic development many mature hematopoietic cell...
Acute myeloid leukemia (AML) is a disease characterized by neoplastic transformation and abnormality of progenitor cells differentiation from cells. In AML there heterogeneous in hematopoietic cells, this has been identified affects the balance between proliferation, survival body Mutation FMS-like tyrosin kinase 3 (FLT3) gene causes overexpression which one most often found mechanism that coul...
Human foamy virus can establish persistent infections in human hematopoietic cell lines, such as H92.1.7 (erythroblastoid cells), Jurkat (CD4+ T cells), and U937 (myeloid-monocytic cells). The infection is characterized by constant production of infectious viruses (for > 2 1/2 years) with no cytopathic effects on the host cells. Electron microscopy of the infected cells showed a viral morpholog...
Interleukin-3 (IL-3) is capable of supporting the proliferation of a broad range of hematopoietic cell types, whereas granulocyte colony-stimulating factor (G-CSF) and macrophage CSF (M-CSF) represent critical cytokines in myeloid differentiation. When this was investigated in a pluripotent-stem-cell-based hematopoietic differentiation model, IL-3/G-CSF or IL-3/M-CSF exposure resulted in the co...
PU.1 is a member of the Ets family of transcription factors and plays an essential role in the development of both myeloid and lymphoid cells. To examine zebrafish pu.1 (zpu.1) expression in subpopulations of blood cells during zebrafish development, we linked a 9-kb zebrafish genomic fragment upstream of the zpu.1 initiator codon to green fluorescent protein (GFP) and microinjected this constr...
Plumbum (Pb) is a heavy metal toxin that causes many pathophysiological effects in various systems of the human body. It has previously been reported that excessive lead trioxide causes hematopoietic system toxicity. Mesenchymal stem cells (MSCs), as cells with self-renewal and multipotent differentiation potential, play a supportive role in hematopoietic function. Lead is well known to interfe...
The utility of flow cytometry as a useful diagnostic modality for the assessment of hematopoietic neoplasms has been established beyond doubt. In fact, it is now an integral part of the diagnosis and classification of various diseases like leukemias and lymphomas along with molecular studies and cytogenetics. Prognostication and disease monitoring by flow cytometry is also being recognized incr...
HSCs are rare cells that have the unique ability to self-renew and differentiate into cells of all hematopoietic lineages. The lack of donors and current inability to rapidly and efficiently expand HSCs are roadblocks in the development of successful cell therapies. Thus, the challenge of ex vivo human HSC expansion remains a fertile and critically important area of investigation. Here, we show...
