Methods and compositions are provided for combined transplantation of a solid organ and hematopoietic cells to a recipient, where tolerance to the graft is established through development of a persistent mixed chimerism. An individual with persistent mixed chimerism, usually for a period of at least six months, is able to withdraw from the use of immunosuppressive drugs after a period of time sufficient to establish tolerance.

Combined organ and hematopoietic cells for transplantation tolerance of grafts

Methods and compositions are provided for combined transplantation of a solid organ and hematopoietic cells to an HLA mismatched recipient, where tolerance to the graft is established through development of a persistent mixed chimerism. An individual with persistent mixed chimerism, usually for a period of at least six months, is able to withdraw from the use of immunosuppressive drugs after a period of time sufficient to establish tolerance.

Combined organ and hematopoietic cells for transplantation tolerance of HLA mismatched grafts

In one aspect, the present invention provides a method for treating cancer comprising tumor cell vaccination in combination with hematopoietic and immune cell transplantation. In some embodiments, the method involves autologous tumor cell vaccination prior to autologous hematopoietic and immune cell transplantation. In another aspect, the present invention provides a method of purifying tumor cells from a subject in preparation for vaccination.

Tumor vaccination in combination with hematopoietic cell transplantation for cancer therapy

Residual, refractory or relapsed cancer is treated by immunostimulation in the presence of allogeneic immune effector cells, optimally in combination with radiation therapy. The methods of the disclosure induce a systemic allogeneic anti-tumor immune response that results in tumor regression in untreated sites of disease, i.e. non-injected, non-irradiated, etc.

Methods for cancer treatment

Cancer treatment is provided, by irradiating an individual with a localized, high single dose or short course of doses at a primary tumor site; collecting T cells from the individual after a period of time sufficient activation of an anti-tumor response; treating the individual with an effective dose of dose of chemotherapy; and reintroducing the T cell population back to the individual.
