Cultures of Friend erythroleukemia cells were subjected to the antibiotics trimethoprim (T) and sulfamethoxazole (S) at levels equal to or below the usual therapeutic range. At T 8 microgram/ml and S 40 microgram/ml, cell growth was arrested, cells appeared megaloblastic, and the examination of cell-cycle distribution by flow microfluorimetry revealed arrest in S phase. With a tenfold reduction...

Starting point for the present work was the assumption that the cell line MuMac-E8 represents a murine cell population with stem cell properties. Preliminary studies already pointed to the expression of stem-cell associated markers and a self-regenerative potential of the cells. The cell line MuMac-E8 should be examined for their differential stage within stem cell hierarchy. MuMac-E8 cells wer...

One of the most important tasks biotechnology and regenerative medicine is to achieve long-term expansion hematopoietic stem cells. promising approaches optimizing cultures cells creation a microenvironment in form feeder stromal layers, which allows for reproduction combination soluble cytokines growth factors necessary hematopoiesis promotes an increase their proliferation [1,2].

Background  The mammary gland in humans is a dynamic organ that undergoes significant developmental changes during pregnancy, lactation, and involution. Stem cells derived from human breast milk possess the adult stem cell-like characteristics such as self-renewal, proliferative and differentiate potential. This source of stem cells avoids invasive procedures and the ethical controversy of emb...

The BCR/ABL oncogene causes human chronic myelogenous leukemia (CML), a myeloproliferative disease characterized by massive expansion of hematopoietic progenitor cells and cells of the granulocyte lineage. When transfected into murine hematopoietic cell lines, BCR/ABL causes cytokine-independence and enhances viability. There is also growing evidence that p210(BCR/ABL) affects cytoskeletal stru...

Background: Chronic myeloid leukemia (CML) is a myeloproliferative hematopoietic malignancy with a heterogeneous proliferation of hematopoietic cells in the bone marrow. The ocular manifestations are rare symptoms of CML. In this case report, a CML patient with retinal hemorrhage is reported as an uncommon symptom. Case presentation: A 35-year-old man was referred due to decreased right eye vi...

The goal of this study was to assess the effects Hematopoietic Progenitor Cells (HSCs) on full-thickness cutaneous wounds healing in rabbits. Twenty clinically healthy adult New Zealand White rabbits were used study; under aseptic technique and general anesthesia excisional wound; 20 mm x made back. randomly partitioned into two. In first group (control group), treated with 3ml saline solution....

Granulocyte colony-stimulating factor (G-CSF) is a hematopoietic cytokine which controls the differentiation and growth of hematopoietic cells in the bone marrow. We report a severe aplastic anemia (SAA) patient with false-negative 99mTc sodium phytate bone marrow imaging findings under concurrent G-CSF therapy. The first bone marrow imaging showed a normal bone marrow activity. However, the bo...

objective: cd133+ umbilical cord blood cells were identified as a hematopoietic stem cell which has the capacity for extensive self-renewal and differentiation. the aim of this study was to identify the effect of staurosporine (sts), a wellknown protein kinase inhibitor on differentiation of cd133+ cells into neural cells. materials and methods: cd133+ cells were enriched by immunomagnetic bead...

Circulating osteogenic precursor (COP) cells are a population of progenitor in the peripheral blood with capacity to form bone vitro and vivo . They have characteristics mesenchymal stem pool found marrow; however, more recently, COP has been identified markers hematopoietic lineage such as CD45 CD34. While this associated several pathologies, lack cell culture models inconsistent characterizat...
