    • A composition comprising bone marrow cells (BMC) and demineralized bone matrix (DBM) and/or mineralized bone matrix (MBM), optionally comprising bone morphogenetic protein (BMP), particularly for use in bone marrow transplantation, into bone marrow cavity or into extraskeletal sites, and methods of transplantation/implantation thereof. The composition and methods of the invention enable restoring and/or enhancing the formation of hematopoiectic microenvironment originating from the transplanted BMC, and are useful in the treatment of hematopoietic disorders, such as deficiency of stem cells and/or their products, genetic conditions resulting in abnormal stem cells and/or products, or hematopoietic disorders of malignant or non-malignant origin. The composition and method of the invention may also be used for the induction of graft tolerence, for the prevention of graft-v-host disease. It is mostly important that the compositions and methods of the invention may be applied for the treatment of diseases affecting primarily or secondarily the stromal microenvironment that supports and regulates hematopoiesis. Further provided is a kit for transplantation into a mammal of BMC in admixture with DBM and/or MBM.

    • The present invention features a method of inducing donor-specific tolerance in a host. Tolerogenic treatments of the present invention may be administered to a host prior to transplantation of donor-derived materials. The tolerogenic treatment involves (1) administering an immunosuppressive agent to a host mammal in a non-myeloablative regimen sufficient to decrease, but not necessarily to eliminate, the host mammal's functional T lymphocyte population; (2) infusing donor antigens from a non-syngeneic donor into the host mammal; (3) eliminating those host T lymphocytes responding to the infused donor antigens using a non-myeloablative dose of lymphocytotoxic or tolerizing agent; and (4) administering donor hematopoietic cells to the host mammal. Donor lymphoid cells used for cell therapy of a host mammal can be depleted of host specific immunological reactivity by methods essentially similar to those use for tolerizing a host mammal prior to transplantation.
    • 本发明的特征在于在宿主中诱导供体特异性耐受的方法。 本发明的耐受性治疗可以在移植供体来源的材料之前施用于宿主。 耐受性治疗涉及(1)以足以减少但不一定消除宿主哺乳动物功能性T淋巴细胞群体的非骨髓清除方案向宿主哺乳动物施用免疫抑制剂; (2)将来自非同基因供体的供体抗原输入宿主哺乳动物; (3)使用非清髓剂量的淋巴细胞毒性或耐受剂消除对输注的供体抗原的响应的宿主T淋巴细胞; 和(4)向宿主哺乳动物施用供体造血细胞。 用于宿主哺乳动物细胞治疗的供体淋巴细胞可以通过基本上类似于用于在移植前耐受宿主哺乳动物的那些方法来消耗宿主特异性免疫反应性。
