چکیده

In a search for novel growth factors, we discovered that human interleukin-20 (IL-20) enhanced colony formation by CD34+ multipotential progenitors. IL-20 had no effect on erythroid, granulocyte-macrophage, or megakaryocyte progenitors. IL-20 transgenic mice increased the numbers and cell cycling of multipotential but not other progenitors. IL-20 administration to normal mice significantly increased only multipotential progenitor cells, demonstrating that IL-20 significantly influences hematopoiesis, with specificity toward multipotential progenitors. This is the first cytokine with such specificity identified.

Expansion of Non-Enriched Cord Blood Stem/Progenitor Cells CD34+ CD38- Using Liver Cells

Many investigators have used xenogeneic, especially murine stromal cells and fetal calf serum to maintain and expand human stem cells. The proliferation and expansion of human hematopoietic stem cells in ex vivo culture were examined with the goal of generating a suitable protocol for expanding hematopoietic stem cells for patient transplantation. Using primary fetal liver cells, we established...

C/EBP deficiency results in hyperproliferation of hematopoietic progenitor cells and disrupts macrophage development in vitro and in vivo

CCAAT enhancer binding protein(C/ EBP ) inhibits proliferation in multiple cell types; therefore, we evaluated whether C/EBP -deficient hematopoietic progenitor cells (HPCs) have an increased proliferative potential in vitro and in vivo. In this study we demonstrate that C/EBP / fetal liver (FL) progenitors are hyperproliferative, show decreased differentiation potential, and show increased sel...

Synergistic interactions between interleukin-11 and interleukin-4 in support of proliferation of primitive hematopoietic progenitors of mice.

Interleukin-11 (IL-11) is a newly identified lymphohematopoietic cytokine originally derived from the primate bone marrow stromal cell line, PU-34. Separately, we reported that IL-11 augments IL-3-dependent proliferation of primitive murine hematopoietic progenitors in culture. We have now examined the synergistic interactions between IL-11 and IL-4 in support of colony formation from marrow ce...

EXPANSION OF HUMAN CORD BLOOD PRIMITIVE PROGENITORS IN SERUM-FREE MEDIA USING HUMAN BONE MARROW MESENCHYMAL STEM CELLS

Ex vivo expansion of human umbilical cord blood cells (HUCBC) is explored by several investigators to enhance the repopulating potential of HUCBC. The proliferation and expansion of human hematopoietic stem cells (HSC) in ex vivo culture was examined with the goal of generating a suitable clinical protocol for expanding HSC for patient transplantation. Using primary human mesenchymal stem ...

Multipotential hematopoietic progenitor cells from embryos developed in vitro engraft unconditioned W41/W41 neonatal miceB.

BACKGROUND AND OBJECTIVES The first hematopoietic stem cells (HSC) in the mouse able to give rise to the adult hematopoietic system emerge at embryonic day (E) 10.5 in the intraembryonic aorta-gonads-mesonephros (AGM) region, as demonstrated by transplantation into irradiated adult recipients. It has been shown by transplantation into conditioned neonatal or hematopoietic mutant adult recipient...
