BACKGROUND Strategies aiming at minimization or elimination of systemic immunosuppression are key immediate goals for clinical expansion of vascularized composite allotransplantation (VCA). We compared the in vitro and in vivo immunomodulatory efficacy of adipose-derived mesenchymal stem cells (AD-MSCs) and bone marrow (BM)-derived MSCs in a rat VCA model.(More)
PURPOSE The feasibility of hand allotransplantation has been demonstrated. The purpose of the article is to report the (1) functional return, (2) psychosocial outcomes, (3) clinical and histological assessment for rejection, (4) complications, and (5) graft survival in the 2 American hand transplant recipients. METHODS We present 2 patients 106 and 81(More)
Since May 2002 all groups performing hand transplantations have supplied detailed information to the International Registry on Hand and Composite Tissue Transplantation. This report provides a review of all hand transplants performed to date. From September 1998 to February 2006 eighteen male patients underwent 24 hand/forearm/digit transplantations (eleven(More)
A new differentiation pathway for CD4−CD8− (DN) T cells has recently been identified that exhibits the potent function of peripheral converted DN T cells in suppressing immune responses and provides the potential to treat autoimmune diseases. The aim of this study was to determine if the DN T cells converted from CD4+ T cells of NOD mice retain the(More)
A commentary on Mesenchymal stem cells are short-lived and do not migrate beyond the lungs after intravenous infusion Mesenchymal stromal cells (MSCs) are under investigation for clinical application. Despite approval by the United States Food and Drug Administration for MSC use in pediatric steroid-refractory acute GvHD after allogeneic hematopoi-etic stem(More)
BACKGROUND We and others have shown that mixed allogeneic chimerism induces donor-specific tolerance to composite tissue allografts across major histocompatibility complex barriers without the need for immunosuppression. However, a delay period between bone marrow transplantation and limb allotransplantation is required, making such protocols impractical(More)
Successful hand transplantation depends upon an extensive, well-coordinated system with resources and experience in both upper extremity and transplant surgery. This description of such a system is drawn from the experience of the Louisville, Kentucky, Hand Transplant Program, which achieved the world's first successful hand transplant in January 1999, and(More)
Conventional breast cancer extirpation involves resection of parts of or the whole gland, resulting in asymmetry and disfiguration. Given the unsatisfactory aesthetic outcomes, patients often desire postmastectomy reconstructive procedures. Autologous fat grafting has been proposed for reconstructive purposes for decades to restore form and anatomy after(More)
Over the past century, the concept of interfering with the immune response at various sites by blocking the formation, stimulation, proliferation, and differentiation of lymphocytes has led to relentless development of new immunosuppressive drugs. These agents are associated with reduced risk of short- and long-term toxicity and have dramatically improved(More)
Skin rejection after hand transplantation is characterized by a maculopapular erythematous rash that may be diffuse, patchy or focal, and distributed over forearms and dorsum of the hands. This 'classical' pattern of rejection usually spares the skin of the palm and does not affect the nails. Herein, we report the experience on four cases presenting with an(More)
