BACKGROUND Although transplantation of musculoskeletal allografts in humans is technically feasible, the adverse effects of long-term immunosuppression subject the patient to high risks for correcting a non-life-threatening condition. Achieving immunologic tolerance to musculoskeletal allografts, without the need for chronic immunosuppression, could expand(More)
Thymic tissue transplantation has been performed previously in adult mice to induce donor-specific tolerance across allogeneic and xenogeneic barriers. We have now attempted to extend this technique to a large animal preclinical model and describe here our initial studies of allogeneic thymic transplantation in miniature swine. Two miniature swine were(More)
BACKGROUND Because of the relative ease of acquisition, increased yield, and improved engraftment characteristics, mobilized peripheral blood progenitor (stem) cells (PBSCs) have recently become the preferred source for hematopoietic stem cell transplantation. In our laboratory, procurement of a megadose of PBSCs is necessary for on-going studies evaluating(More)
Mixed hematopoietic chimerism may provide a treatment for patients with nonmalignant hematologic diseases, and may tolerize patients to organ allografts without requiring chronic immunosuppression. However, the toxicity of the usual conditioning regimens has limited the clinical applicability of this approach. These regimens generally include some level of(More)
BACKGROUND AND PURPOSE The pig is being investigated as an organ donor for humans. Induction of immunologic tolerance to pig tissues in primates would overcome the major immunologic barriers to xenotransplantation. A proven method of inducing tolerance to allografts is by the induction of mixed hematopoietic chimerism by bone marrow transplantation. We are(More)
