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 ...
متن کاملEpigenetic reprogramming induces the expansion of cord blood stem cells.
Cord blood (CB) cells that express CD34 have extensive hematopoietic capacity and rapidly divide ex vivo in the presence of cytokine combinations; however, many of these CB CD34+ cells lose their marrow-repopulating potential. To overcome this decline in function, we treated dividing CB CD34+ cells ex vivo with several histone deacetylase inhibitors (HDACIs). Treatment of CB CD34+ cells with th...
متن کاملNanofiber Expansion of Umbilical Cord Blood Hematopoietic Stem Cells
Background The aim of this study was the ex vivo expansion of Umbilical Cord Blood hematopoietic stem cells on biocompatible nanofiber scaffolds. Materials and Methods CD133+ hematopoietic stem cells were separated from umbilical cord blood using MidiMacs (positive selection) system by means of monocolonal antibody CD133 (microbeads) subsequently, flowcytometry method was done to asses...
متن کاملOscillations in Notch Signaling Regulate Maintenance of Neural Progenitors
Expression of the Notch effector gene Hes1 is required for maintenance of neural progenitors in the embryonic brain, but persistent and high levels of Hes1 expression inhibit proliferation and differentiation of these cells. Here, by using a real-time imaging method, we found that Hes1 expression dynamically oscillates in neural progenitors. Furthermore, sustained overexpression of Hes1 downreg...
متن کاملRapamycin Inhibits Expansion of Cord Blood Derived NK and T Cell
Background: The mammalian target of rapamycin (mTOR) is important in hematopoiesis. Despite the central role of mTOR in regulating the differentiation of immune cells, the effect of mTOR function on cord blood mononuclear cells is yet to be defined. Objectives: To evaluate the effect of mTOR inhibition, using rapamycin on the proliferation and apoptosis of cord blood mononuclear cells, as well ...
