Available in PDF, EPUB and Kindle. Book excerpt: The application of composite tissue techniques is constrained by the susceptibility of skin to rejection. The aim of this thesis is to improve our understanding of skin rejection and find ways to avoid it, in order to enable expansion of the application of composite tissue transplantation techniques. The first part of the thesis explores the consequences and mechanism of skin rejection in rat models. These studies indicate that in the event of allograft failure, there is minimal damage to the vascular pedicle of a composite tissue allotransplant, even after full rejection, making retransplantation possible. Furthermore, there is only mild damage to the recipient tissues, indicating that the second transplant would not be limited in form or function by recipient tissue bed damage. Finally, the studies indicate that there are significant differences between the mechanism of rejection of skin in composite tissue transplants and conventional skin grafts. This means that much of the historical data relating to skin graft rejection is not necessarily relevant to composite tissue allotransplantation. The second part of the thesis uses swine models to explore ways to overcome skin rejection while avoiding the toxicity of chronic systemic immunosuppression, through tolerance induction, and site specific therapy. Previous experience in organ and composite tissue allotransplantation models are analysed to develop the hypothesis that high-level chimeras are tolerant to vascularised skin allotransplants. In utero and adult chimerism induction models are then used in an attempt to attain moderate-level chimeras. A vascularised skin allotransplant model is developed. Finally, the hypothesis is confirmed with the transplantation of a vascularised skin allotransplant on to moderate-level chimeras with the achievement of tolerance. In addition, site-specific therapy is used in an attempt to avoid the side-effects of chronic high-dose systemic immunosuppression. This led to prolongation of skin survival, but eventual skin rejection.

Download or read book Composite Tissue Allografts written by Jean-Michel Dubernard and published by MIT Press. This book was released on 2002 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transplanting hands -- a model of composite tissue grafting -- began in Lyons in November 1998 with the transplant of one hand and then, in January 2000, of two, both with the support of the Mérieux Foundation. Advances in immunosuppression made possible some unusual transplants of tissue, such as bones, knee-joints, femurs and larynx. From these stemmed the first attempts to transplant hands. This book looks at the long-term results of reattaching hands that have been accidentally amputated. It reviews all the problems -- technical, immunological, nervous, functional and psychological -- that surgeons encountered during and after the transplants. Surgeons, transplant experts, immunologists, dermatologists, psychiatrists, neurophysiologists, physiotherapists and re-education experts will also find here answers to their ethical and legal questions about removing tissue from donors, as well as information about composite tissue grafts in plastic and reconstructive surgery.

Download or read book Modelling and Characterisation of in Vivo Human Skin Graft Rejection for the Investigation of Regulatory T Cell Therapy in Vascularised Composite Allotransplantation written by Fadi Issa and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Vascularised composite allograft (VCA) transplantation is revolutionising the field of plastic surgery. It reconstructs the most complex tissue defects effectively, achieving a new functional and cosmetic gold standard. However, VCA transplantation is currently limited by high rates of acute rejection and the need for patients without life-threatening conditions to be maintained on immunosuppression for life. Skin is the most problematic component of VCA transplants. It stimulates a vigorous immune response and is highly susceptible to rejection, even in the presence of potent immunosuppression. In order to expand the field of VCA transplantation and improve outcomes, the morbidity and mortality associated with immunosuppression need to be minimised or eliminated. This would require manipulation of the immune response to allow long-term survival in the absence of immunosuppression, in other words tolerance. A particular focus on the immune response directed against skin is required. Tolerance to skin allografts may be achievable with the use of regulatory T cells (Treg). Due to relatively few clinical cases, human skin transplantation is a poorly investigated area. The studies in this thesis were therefore designed to elucidate the characteristics of human skin rejection using a novel humanised mouse model, testing the hypothesis that human Treg could prevent human skin rejection in vivo. In Chapters 3 and 4 we develop a system whereby human skin rejection may be modelled effectively in vivo. Subsequently we investigate the unique characteristics of human skin rejection using this model. In Chapter 5 we demonstrate the capacity for Treg to prevent human skin rejection and investigate the systemic and local cellular changes resulting from Treg therapy. These changes include a reduction in the number of circulating proliferating T cells, a preservation of skin microvasculature, and a reduction in skin-infiltrating CD8+ leukocytes. Treg migrate to the allograft-draining lymph node and into the skin allograft to regulate immune responses. We demonstrate the importance of expansion or activation of Treg for their suppressive activity and the requirement for these cells to be derived from the allograft recipient for efficient regulation to be achieved. Treg cellular therapy has already been trialed clinically for the prevention of graft- versus-host disease after haematopoietic stem cell transplantation. The use of Treg in transplantation is therefore on the horizon. The unique translational data from this study bridge a critical gap between laboratory observations and the clinic. These data therefore form the basis upon which future clinical trials of Treg in skin or VCA transplantation may be performed.

Download or read book Advances in Regenerative Medicine Role of Nanotechnology and Engineering Principles written by Venkatram Prasad Shastri and published by Springer Science & Business Media. This book was released on 2010-08-14 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the NATO Advanced Research Workshop (ARW) on “Nanoengineered Systems for Regenerative Medicine” that was organized under the auspices of the NATO Security through Science Program. I would like to thank NATO for supporting this workshop via a grant to the co-directors. The objective of ARW was to explore the various facets of regenerative me- cine and to highlight role of the “the nano-length scale” and “nano-scale systems” in defining and controlling cell and tissue environments. The development of novel tissue regenerative strategies require the integration of new insights emerging from studies of cell-matrix interactions, cellular signalling processes, developmental and systems biology, into biomaterials design, via a systems approach. The chapters in the book, written by the leading experts in their respective disciplines, cover a wide spectrum of topics ranging from stem cell biology, developmental biology, ce- matrix interactions, and matrix biology to surface science, materials processing and drug delivery. We hope the contents of the book will provoke the readership into developing regenerative medicine paradigms that combine these facets into cli- cally translatable solutions. This NATO meeting would not have been successful without the timely help of Dr. Ulrike Shastri, Sanjeet Rangarajan and Ms. Sabine Benner, who assisted in the organization and implementation of various elements of this meeting. Thanks are also due Dr. Fausto Pedrazzini and Ms. Alison Trapp at NATO HQ (Brussels, Belgium). The commitment and persistence of Ms.
