A method of increasing the relative number of cells expressing one or more stem cell markers in a cell population including committed cells is described. The method comprises: i. contacting the cell population with an agent that operably engages said committed cells; and ii. incubating committed cells that are engaged by said agent such that the relative number of cells expressing one or more stem cell markers increases as a result of said engaging.

The present invention is directed to a new bone marrow stromal stem cell (BMSSC) marker, CD18, for use in selecting a population of cells enriched in BMSSCs, from bone marrow cells, adipose cells, or peripheral blood. The invention is further directed to methods for selecting a population of cells enriched in BMSSCs based on the selective expression of CD18 on their surface, using techniques known in the art such as fluorescent assisted cell sorting, an immunomagnetic method, flow microfluorimetry, immunofluorescence, immunoperoxidase staining, radioimmunoassay and immunoaffinity chromatography. The invention is further directed to the BMSSCs isolated based on CD18 expression, and their use to treat various diseases. In one aspect, the HMSSCs are transformed with a vector having a normal gene for CD18, and the transformed BMSSCs are administered to treat bone degenerative diseases and diseases of bone involving abnormal expression of CD18 expression of CD18.

The invention provides an isolated tissue comprising a source of millions of postnatal stem cells expressing embryonic stem cell markers, and a method of storing or banking such isolated tissue to provide stems cells for later therapeutic use for the donor or for allogeneic transplant with donor permission.

A set of markers for melanoma cancer stem cells are provided. The cells can be prospectively isolated or identified from primary tumor samples, and possess the unique properties of cancer stem cells in functional assays for tumor initiation, cancer stem cell self-renewal and differentiation. In addition, cancer stem cells can be used as a predictor for disease progression. The CSC have the phenotype of being positive for expression CD271.

A method for enriching a population of somatic mammary stem cells or mammary tumor stem cells based on low-density lipoprotein receptor-related protein 6 (LRP6). Also included are methods for screening for LRP6 modulators, as well as methods for reducing Wnt signaling, for treating Wnt signaling-related diseases, for detecting mammary basal-like cells, for diagnosing basal-like breast cancer, and for inhibiting proliferation of a tumor expressing LRP6, and compositions thereof.

The present invention relates to a medium composition for transforming stem cells from an aged person into young stem cells, and more particularly to a medium composition for culturing stem cells, which is used to rejuvenate stem cells from an aged person so as to have characteristics similar to those of the stem cells of young people, and to a method for rejuvenating stem cells, which comprises culturing stem cells from an aged person in the medium composition. According to the present invention, even mesenchymal stem cells collected from over 60 years old patients can be transformed into young mesenchymal stem cells having high differentiation ability, high telomerase activity, and high ability to express stem cell markers. Thus, the present invention can significantly increase the efficacy of cell therapy employing mesenchymal stem cells.

The present invention pertains to therapeutic methods which are based on the use of an agent specifically binding a tumor-associated carbohydrate antigen for the treatment of cancer stem cells and related diseases. Also provided are diagnostic and prognostic methods using a tumor- associated carbohydrate antigen as marker for cancer stem cells.

The invention relates to purposes of icaritin in preparing medicaments for inhibiting liver cancer stem cells. Icaritin can inhibit liver cancer stem cells by inhibiting expressions of liver cancer stem cell markers. Accordingly, the invention provides a further research direction of liver cancer targeted therapy, and it is hopeful for fundamentally curing liver cancer by inhibiting liver cancer stem cells.

Markers of acute myeloid leukemia stem cells (AMLSC) are identified. The markers are differentially expressed in comparison with normal counterpart cells, and are useful as diagnostic and therapeutic targets.

This invention generally relates to a design and method for developing novel anti-tumor / cancer drugs, vaccines and therapies, using microRNA (miRNA) and its shRNA homologues / derivatives. More particularly, the present invention relates to the use of a nucleic acid composition capable of expressing mir-302-like gene silencing effectors upon delivery into human cells and then silencing mir-302-targeted cell cycle regulators and oncogenes, resulting in an inhibitory effect on tumor / cancer cell growth and metastasis. Mir-302 is the most predominant miRNA found in human embryonic stem (hES) and induced pluripotent stem (iPS) cells, yet its function is unclear. The present invention establishes that in humans mir-302 concurrently suppressed both cyclin-E-CDK2 and cyclin-D-CDK4 / 6 pathways and eventually blocked over 70% of the G1-S transition. Simultaneously, mir-302 also silences BMI-1, a cancer stem cell marker, and subsequently promotes the tumor suppressor functions of p16Ink4a and p14 / p19Arf in inhibiting CDK4 / 6-mediated cell proliferation. Therefore, the present invention for the first time reveals the tumor suppressor function of mir-302 in humans. This novel finding advances the design and method for developing new cancer drugs, vaccines and therapies directed against multiple kinds of human tumors and cancers, in particular including, but not limited, malignant skin, prostate, breast and liver cancers as well as various tumors.
