Patents by Inventor Yukoh Aihara

Yukoh Aihara has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Human hematopoietic stem cell
    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.
    Type: Grant
    Filed: June 6, 1995
    Date of Patent: June 22, 1999
    Assignee: Systemix, Inc.
    Inventors: Ann Tsukamoto, Charles M. Baum, Yukoh Aihara, Irving Weissman

  • Identification and isolation of human hematopoietic stem cells
    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.
