Abstract:
A method of expanding and maintaining human embryonic stem cells (ESCs) in an undifferentiated state by culturing the ESCs in a suspension culture under culturing conditions devoid of substrate adherence is provided. Also provided are a method of deriving ESC lines in the suspension culture and methods of generating lineage-specific cells from ESCs which were expanded in the suspension culture of the present invention.
Abstract:
Monocyte derived adult stem cells (MDSCs) isolated from peripheral blood of mammals are provided, along with pharmaceutical compositions containing an MDSC, kits containing a pharmaceutical composition, and methods of preparing, propagating and using MDSCs or differentiated derivatives thereof. The uses of these biological materials include methods of treating disorders or diseases, as well as methods of ameliorating a symptom associated with any such disorder or disease including disorders or diseases associated with platelets.
Abstract:

Particular embodiments provide for defined culture media useful for growing these cells, and grafts comprising these cells. The invention finds use in methods for reconstituting, repairing, and regenerating tissue damage.
Abstract:
The present invention relates to a method of isolating and culturing mesenchymal stem cells using umbilical cord blood that is most ideal for cell therapy. The method comprises adding an anti-coagulant to umbilical cord blood having a volume of more than 45 ml per unit, which is obtained within 24 hours after parturition; diluting the resulting mixture of the anti-coagulant and umbilical cord blood with an αMEM (alpha-minimum essential medium), followed by centrifugation to harvest monocytes; and subjecting the obtained monocytes into suspension culture in the αMEM containing Stem Cell Factor, GM-CSF (granulocyte-macrophage colony-stimulating factor), G-CSF (granulocyte colony-stimulating factor), IL-3 (interleukin-3) and IL-6 (interleukin-6).
Abstract:
Methods of ex-vivo expansion of fetal and/or adult progenitor, and umbilical cord blood, bone marrow or peripheral blood derived stem cells in bioreactors for bone marrow transplantation, transfusion medicine, regenerative medicine and gene therapy.
Abstract:
A method for the ex-vivo expansion of mammalian hematopoietic stem cells (HSC) comprises culturing isolated HSC in a culture system comprising a culture medium in the presence of a stem cell expansion promoting factor (SCEPF) which may be obtained by culturing murine stromal cells in the presence of an amount of leukemia inhibitory factor (LIF) sufficient to stimulate the production and secretion of said expansion promoting factor.
Abstract:
Methods are provided for deriving and propagating passagable pluripotent stem cells from early primate embryos. The passagable pluripotent stem cells are capable of differentiating into a variety of intermediate stem cell types through modified in vitro culture conditions, and as such are useful as a model for early development, and for treatment of a variety of genetic and degenerative diseases and for assay compounds to determine their effect on development.
Abstract:
Myeloproliferative leukemia receptor (mpl) ligands, such as thrombopoietin, act on a primitive subpopulation of human stem cells having the characteristics of self-renewal and ability to give rise to all hematopoietic cell lineages. Thrombopoietin supports both megakaryocytic differentiation and primitive progenitor cell expansion of CD34 + and CD34 + sub-populations (CD34 + Lin - , CD34 + Thy-1 + Lin - , and CD34 + Lin - Rh123 lo ). Thrombopoietin also stimulated quiescent human stem cells to begin cycling. Thus, mpl ligands are useful for expanding primitive stem cells for restoration of hematopoietic capabilities and for providing modified human stem cells for gene therapy applications.
