Abstract: A nephrospheroid comprising urine-derived epithelial cells, the nephrospheroid is capable of forming a tubular nephric tissue upon transplantation. Also provided are methods of producing the nephrospheroid and using same.

Abstract: Methods of treating cancer are provided. Accordingly, there is provided a method of treating cancer in a subject in need thereof, the method comprising administering to the subject an effective amount of an agent capable of (i) specifically binding GABRA2, the agent comprising a therapeutic moiety; and/or (ii) downregulating activity and/or expression of said GABRA2. Also provided are compositions, article of manufactures and methods of diagnosing cancer and monitoring cancer treatment.

Abstract: A method of identifying cancer stem cell markers in a human primary tumor is disclosed. The method comprises: (a) in vivo passaging the primary tumor; and (b) comparing a level of at least one antigen in a first population of passaged tumor cells of the primary tumor with a second population of tumor cells of the primary tumor, wherein an increase in the amount of the antigen in the first population of tumor cells as compared to the amount of the antigen in the second population of tumor cells is indicative of a cancer stem cell marker in the human primary tumor.

Abstract: A method of generating a nephrospheroid is disclosed. The method comprises culturing human adult kidney cells in a culture medium under non-adherent conditions. Uses thereof and other renal cell populations are also disclosed.

Abstract: Isolated populations of fetal renal stem cells and progenitor cells are provided. Also provided are methods of generating and using these isolated populations of cells.

Abstract: Isolated populations of fetal renal stem cells and progenitor cells are provided. Also provided are methods of generating and using these isolated populations of cells.

Abstract: A method of reprogramming a differentiated renal cell towards a progenitor phenotype is disclosed. The method comprises up-regulating in the differentiated renal cell an expression of at least one pluripotency associated gene and/or at least one renal stem cell associated gene, thereby reprogramming the differentiated renal cell towards a progenitor phenotype. Cell populations generated thereby and uses thereof are also disclosed.
