Abstract: A method of generating an isolated population of non graft versus host disease (GvHD) inducing cells comprising a central memory T-lymphocyte (Tcm) phenotype, the cells being tolerance inducing cells and/or endowed with anti-disease activity, and capable of homing to the lymph nodes following transplantation is disclosed. The method comprising: (a) providing a population of at least 70% memory T cells; (b) contacting the population of memory T cells with an antigen or antigens so as to allow enrichment of antigen reactive cells; and (c) culturing the cells resulting from step (b) in the presence of cytokines so as to allow proliferation of cells comprising the Tcm phenotype. Cells generated by the method, pharmaceutical compositions and methods of treatment are also disclosed.

Abstract: A method of transplantation is disclosed. The method comprising administering to a subject in need of transplantation of cells in suspension, a therapeutically effective amount of tolerance inducing anti-third party cytotoxic T-lymphocytes (CTLs), wherein the tolerance inducing anti-third party CTLs are generated by directing T-lymphocytes of a donor against a third party antigen or antigens, the tolerance inducing anti-third party CTLs being substantially depleted of T-lymphocytes capable of developing into alloreactive CTLs, and wherein the tolerance inducing anti-third party CTLs do not comprise cells having a central memory T-lymphocyte (Tcm) phenotype, wherein the cells in suspension comprise non-hematopoietic cells or hematopoietic cells which are not stem cells. Methods of treating and kits are also provided.

Abstract: A method of generating an isolated population of cells comprising anti-third party cells having a central memory T-lymphocyte (Tcm) phenotype, the cells being tolerance-inducing cells and/or endowed with anti-disease activity, and capable of homing to the lymph nodes following transplantation is disclosed. The method comprising: (a) contacting peripheral blood mononuclear cells (PBMC) with a third party antigen or antigens in the presence of IL-21 so as to allow enrichment of antigen reactive cells; and (b) culturing the cells resulting from step (a) in the presence of IL-21, IL-15 and IL-7 in an antigen free environment so as to allow proliferation of cells comprising the central memory T-lymphocyte (Tcm) phenotype.

Abstract: A method of conditioning a subject in need of transplantation of progenitor cells in suspension of a tissue of interest is disclosed. The method comprising: (a) administering to a subject a therapeutically effective amount of an agent capable of inducing damage to the tissue of interest, wherein the damage results in proliferation of resident stem cells in the tissue; and subsequently (b) subjecting the subject to an agent which ablates the resident stem cells in the tissue. A method of transplanting progenitor cells in suspension of a tissue of interest to a subject in need thereof is also disclosed.
