/1860943101

Several textbooks have been published that discuss just one or two of the areas concerning tissue and organ replacement. This important book brings together all the different approaches for the first time. The contributors are established experts in their respective fields.The multidisciplinary nature of the text will appeal to students, scientists and clinicians from a wide spectrum of disciplines who are considering a future in organ replacement therapy, as well as to those who have so far only learnt of the developments in organ transplantation or replacement in the lay media. The field is moving very fast indeed -- transplant surgeons continue to redefine what is possible and new products that were just laboratory curiosities a few years ago are beginning to enter clinics around the world and improve the quality of life for thousands of people. The promise of the various technologies described in this book, if realised, will make a profound and lasting impact on both the way the health care industry operates and the way we view the human body.

Bio-hybrid organs and tissues for patient therapy: A ~ These strategies seek to reconstruct damaged organs tissues by cell transplants or bioartificial tissues or by inducing resident cells to reconstruct them in situ. The ultimate goal will be the development of tissue and organ homologues from stem cells and biomaterials that mimic extracellular matrix in vivo providing not only the geometry and physico-chemical properties to maximize the .

Decellularization / SpringerLink ~ These biologic scaffolds made of ECM, typical in reconstructive surgery, are used in a variety of applications, including regenerative medicine strategies for increasing tissue and organ replacement [4]. In in vitro studies, relying on the bioreactor, researchers have examined the effect of these scaffolds on cell proliferation and organ structure. In in vivo implantations of decellularized .

Strategies for using mathematical modeling approaches to ~ The size of a source organ (i.e., the surface area of a barrier tissue or the volume of a parenchymal tissue) can have a big impact on the extent to which the organ model affects the composition of the systemic pool. For example, the relative sizes of the major organs involved in ADME—drug absorption (e.g., GI tract), distribution (e.g., adipose tissues, the blood-brain barrier), metabolism .

Immunomodulation - ScienceDirect ~ The immunological rejection of transplanted tissues and organs is one of the major problems in organ replacement, and immunosuppression still carries significant long-term side effects. One solution may reside in novel therapeutic strategies that strive to prevent the need for long-term and high dose immunosuppression. These strategies involve immunologically modifying the foreign proteins on .

Electrospinning and 3D bioprinting for intervertebral disc ~ Novel bioink formulations have been proposed to aid in the healing process via host tissue interactions as well as replace damaged tissue. 37 Thus, novel bioinks have the potential to create bioprinted IVDs with improved strength, and circumvent the hydrogel challenges, for example, via optimized composition of polymers, enhanced cross‐linking or inclusion of additional support structures .

Vascularization Strategies for Tissue Engineering / Tissue ~ Tissue engineering is currently limited by the inability to adequately vascularize tissues in vitro or in vivo.Issues of nutrient perfusion and mass transport limitations, especially oxygen diffusion, restrict construct development to smaller than clinically relevant dimensions and limit the ability for in vivo integration. There is much interest in the field as researchers have undertaken a .

Application of inkjet printing to tissue engineering ~ Recent advances in organ printing technology for applications relating to medical interventions and organ replacement are described. Organ printing refers to the placement of various cell types into a soft scaffold fabricated according to a computer‐aided design template using a single device. Computer aided scaffold topology design has recently gained attention as a viable option to achieve .

Biomaterials & scaffolds for tissue engineering ~ Now that tissue engineering strategies are entering clinical practice more routinely, . augment or replace any tissue, organ or function of the body’. This subtle change in definition is indicative of how the field of biomaterials has evolved. Biomaterials have moved from merely interacting with the body to influencing biological processes toward the goal of tissue regeneration. Typically .

3D bioprinting for biomedical devices and tissue ~ As the main process involved in cell growth and reconstruction of organs, tissue regeneration is currently under extensive study. Organ transplantation, replacement and repair are the options for patients with damaged organs depending on the situation and intensity of the damage. Extensively long waiting lists for organ transplantation exist all around the world. According to U.S. Department .

Regenerative medicine: Current therapies and future ~ Organ and tissue loss through disease and injury motivate the development of therapies that can regenerate tissues and decrease reliance on transplantations. Regenerative medicine, an interdisciplinary field that applies engineering and life science principles to promote regeneration, can potentially restore diseased and injured tissues and whole organs.

Biomaterials for hollow organ tissue engineering ~ Tissue engineering is a rapidly advancing field that is likely to transform how medicine is practised in the near future. For hollow organs such as those found in the cardiovascular and respiratory systems or gastrointestinal tract, tissue engineering can provide replacement of the entire organ or provide restoration of function to specific regions.

Bioreactors for tissue engineering: An update - ScienceDirect ~ One of the greatest puzzles in wound healing is how to substitute or replace the defect caused by loss and damaged tissue or organs. In regenerative medicine, Tissue Engineering has been proposed to supply this demand by generating tissues in vitro.Bioreactors are the key to translate these cells and tissue-based constructs into large-scale biological products that are clinically effective .

Generation of functional organs from stem cells / Cell ~ Although organogenesis is a complex process, the organ generation systems described above using stem cells or a combination of stem cells and tissue engineering may be applied, or at least raise the hope, to treat organ failure in humans in the near future. Besides adult tissue stem cells and embryonic stem cells, recent burgeoning and promising development of technology of induced pluripotent .

/ British Society for Immunology ~ Transplantation is the process of moving cells, tissues or organs from one site to another for the purpose of replacing or repairing damaged or diseased organs and tissues. It saves thousands of lives each year. However, the immune system poses a significant barrier to successful organ transplantation when tissues/organs are transferred from one individual to another.

A Whole-Organ Regenerative Medicine Approach for Liver ~ A regenerative medicine approach for liver replacement has recently been described that includes the use of a three-dimensional organ scaffold prepared by decellularization of xenogeneic liver. The present study investigates a new, minimally disruptive method for whole-organ liver decellularization and three different cell reseeding strategies to engineer functional liver tissue. Methods: A .

Organ printing - Wikipedia ~ Organ printing utilizes techniques similar to conventional 3D printing where a computer model is fed into a printer that lays down successive layers of plastics or wax until a 3D object is produced. In the case of organ printing, the material being used by the printer is a biocompatible plastic. The biocompatible plastic forms a scaffold that acts as the skeleton for the organ that is being .

From pulpal stem cells to tooth repair: an emerging field ~ The replacement of lost teeth by engineered dental tissue appears as a fascinating goal. However, the feasibility remains an intriguing question. Is the challenge to create a new tooth acting as a substitute for lost tooth or to regenerate only part of this organ that is enamel, dentin, or dental pulp? Is it possible to exploit stem cells for transplantation purposes to promote matrix .
