  • Patent number: 5928638
    Abstract: The present invention provides a method for optimizing gene transfer into hematopoietic stem cells (HSCs) by contacting the cells with hydroxyurea prior to gene transfer to induce HSCs in G0 into active cell cycle. This method is useful for treating patients suffering from a disease that is suitably treated by gene therapy or involves hematopoietic cells. A method is also provided for enhancing the efficacy of bone marrow transplantation by administering hydroxyurea to increase HSC yields.

  • Patent number: 5914108
    Abstract: Human hematopoietic stem cells are provided by separation of the stem cells from dedicated cells. The stem cells may than be maintained by regeneration in an appropriate growth medium. Means are provided for assaying for the stem cells as to their capability for producing members of each of the hematopoietic lineages. A method for treating a human by implanting a cellular composition comprising greater than 90% human hematopoietic stem cells is also disclosed.

  • Patent number: 5643741
    Abstract: Human hematopoietic stem cells are identified according to expression of specific cell surface markers. Substantially homogenous stem cell compositions are obtained by selective isolation of cells free of markers associated with differentiated cells, while displaying epitopic characteristics associated with the stem cells. The stem cells may then be maintained by regeneration in an appropriate growth medium. Means are provided for assaying for the stem cells as to their capability for producing members of each of the hematopoietic lineages.
