the complexity of multiple sclerosis (ms) and the incompetence of a large number of promise treatments in ms urge us to plan new and more effective therapeutic approaches that aim to suppress ongoing autoimmune responses and induction of local endogenous regeneration. emerging data propose that hematopoietic, mesenchymal and neural stem cells have the potential to restore self-tolerance, to pro...

microglia cells are a subset of central nervous system (cns) macrophages. changes in the cns such as injury, or developmental events, follow by morphological and physiological changes in microglia cells. in this study organotypic brain slice cultures under serum free condition were used to investigate the morphology and lectin histochemistry of microglia and macrophages in the cns in vitro. mic...

BACKGROUND Hematopoietic progenitors are generated in the yolk sac and aorta-gonad-mesonephros region during early mouse development. At embryonic day 10.5 the first hematopoietic stem cells emerge in the aorta-gonad-mesonephros. Subsequently, hematopoietic stem cells and progenitors are found in the fetal liver. The fetal liver is a potent hematopoietic site, playing an important role in the e...

New and effective treatment for acute kidney injury remains a challenge. Here, we induced mouse hematopoietic stem and progenitor cells (HSPC) to differentiate into cells that partially resemble a renal cell phenotype and tested their therapeutic potential. We sequentially treated HSPC with a combination of protein factors for 1 wk to generate a large number of cells that expressed renal develo...

BACKGROUND In spite of its establishment from the peripheral blood of a case with acute myeloid leukemia (AML)-M1, HPB-AML-I shows plastic adherence with spindle-like morphology. In addition, lipid droplets can be induced in HPB-AML-I cells by methylisobutylxanthine, hydrocortisone, and indomethacin. These findings suggest that HPB-AML-I is similar to mesenchymal stem cells (MSCs) or mesenchyma...

Fusion of lysosomes to form a giant cytoplasmic inclusion is a major abnormality expressed by multiple hematopoietic and non-hematopoietic cell types in Chediak-Higashi (C-H) patients. In this study, the extent of involvement of lymphoid cell subpopulations was defined. Purified populations of B cells, natural killer (NK) cells, and helper T cells were obtained from two C-H patients and normal ...

BACKGROUND Human embryonic stem (hES) cells hold considerable promise for cell replacement and gene therapies. Their remarkable properties of pluripotency, self-renewal, and tractability for genetic modification potentially allows for the production of sizeable quantities of therapeutic cells of the hematopoietic lineage. Dendritic cells (DC) arise from CD34+ hematopoietic progenitor cells (HPC...

Background: This article reviews experimental and clinical studies in which neural injuries repaired with bone marrow stromal cells. History: Bone marrow contains two kinds of stem cells: hematopoietic and nonhematopoietic (stromal) stem cell. In vitro studies indicate that bone marrow stromal cells have the capacity of differentiation into other cells (such as neural cell) under treatment wit...

introduction: setting up a system to study the in vitro hematopoiesis is helpful to understand the mechanism of hematopoiesis. the effects of several cytokines and hormones such as erythropoietin (epo) in differentiation of hematopoietic stem cells have been investigated in vivo. there are no records considering the potential differentiation of p19 cell line (embryonic carcinoma cells) to hemat...
