Download or read book Tumor Organoids written by Shay Soker and published by Humana Press. This book was released on 2017-10-20 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cancer cell biology research in general, and anti-cancer drug development specifically, still relies on standard cell culture techniques that place the cells in an unnatural environment. As a consequence, growing tumor cells in plastic dishes places a selective pressure that substantially alters their original molecular and phenotypic properties.The emerging field of regenerative medicine has developed bioengineered tissue platforms that can better mimic the structure and cellular heterogeneity of in vivo tissue, and are suitable for tumor bioengineering research. Microengineering technologies have resulted in advanced methods for creating and culturing 3-D human tissue. By encapsulating the respective cell type or combining several cell types to form tissues, these model organs can be viable for longer periods of time and are cultured to develop functional properties similar to native tissues. This approach recapitulates the dynamic role of cell–cell, cell–ECM, and mechanical interactions inside the tumor. Further incorporation of cells representative of the tumor stroma, such as endothelial cells (EC) and tumor fibroblasts, can mimic the in vivo tumor microenvironment. Collectively, bioengineered tumors create an important resource for the in vitro study of tumor growth in 3D including tumor biomechanics and the effects of anti-cancer drugs on 3D tumor tissue. These technologies have the potential to overcome current limitations to genetic and histological tumor classification and development of personalized therapies.

Download or read book Hepatocyte Transplantation written by S. Gupta and published by Springer Science & Business Media. This book was released on 2002-09-30 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years there has been an increasing need for transplantation, but the number of donor livers available has increased only slightly, despite intensive public relations activities. New concepts in the field of transplantation, for instance the transplantation of living donor organs or the splitting of organs, are urgently required, to safeguard the treatment of patients with severe liver disease. The development and clinical application of cell therapy for patients with liver disease could soon present a significant enhancement of the therapeutic options. The aim of such cell therapy is to repair or improve the biological function of the chronically and acutely damaged liver. Even though systematic trials are not available, individual case reports and small series already show promising clinical results. Present concepts of cell therapy for liver diseases based on the use of primary hepatocytes have recently been considerably extended through new data on the biology of stem cells. The adult haematopoetic stem cell as a pool for hepatocyte grafts - what would be the perspectives for the clinical application? This book is the proceedings of the Falk Symposium No. 126 on `Hepatocyte Transplantation' (Progress in Gastroenterology and Hepatology Part III) held in Hannover, Germany, October 2-3, 2001, and is a forum for basic research, but also for questions concerning clinical applications in the field of hepatocyte transplantation.

Download or read book Human Neural Stem Cells written by Leonora Buzanska and published by Springer. This book was released on 2018-09-12 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes early pioneering achievements in the field of human neural stem cell (hNSC) research and combines them with the latest advances in stem cell technology, including reprogramming and gene editing. The powerful potential of hNSC to generate and repair the developing and adult CNS has been confirmed by numerous experimental in vitro and in vivo studies. The book presents methods for hNSC derivation and discusses the mechanisms underlying NSC in vitro fate decisions and their in vivo therapeutic mode of action. The long-standing dogma that the human central nervous system (CNS) lacks the ability to regenerate was refuted at the end of the 20th century, when evidence of the presence of neurogenic zones in the adult human brain was found. These neurogenic zones are home to human neural stem cells (hNSCs), which are capable of self-renewing and differentiating into neurons, astrocytes and oligodendrocytes. NSCs isolated from human CNS have a number of clinical advantages, especially the innate potential to differentiate into functional neural cells. Nevertheless, their full clinical exploitation has been hindered by limited access to the tissue and low expansion potential. The search for an alternative to CNS sources of autologous, therapeutically competent hNSCs was the driving force for the many studies proving the in vitro plasticity of different somatic stem cells to generate NSCs and their functional progeny. Now the era of induced pluripotent stem cells has opened entirely new opportunities to achieve research and therapeutic goals with the aid of hNSCs.

Download or read book Innovative Medicine written by Kazuwa Nakao and published by Springer. This book was released on 2015-10-13 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to innovative medicine, comprising the proceedings of the Uehara Memorial Foundation Symposium 2014. It remains extremely rare for the findings of basic research to be developed into clinical applications, and it takes a long time for the process to be achieved. The task of advancing the development of basic research into clinical reality lies with translational science, yet the field seems to struggle to find a way to move forward. To create innovative medical technology, many steps need to be taken: development and analysis of optimal animal models of human diseases, elucidation of genomic and epidemiological data, and establishment of “proof of concept”. There is also considerable demand for progress in drug research, new surgical procedures, and new clinical devices and equipment. While the original research target may be rare diseases, it is also important to apply those findings more broadly to common diseases. The book covers a wide range of topics and is organized into three complementary parts. The first part is basic research for innovative medicine, the second is translational research for innovative medicine, and the third is new technology for innovative medicine. This book helps to understand innovative medicine and to make progress in its realization.

Download or read book The Hepatocyte Review written by M. N. Berry and published by Springer Science & Business Media. This book was released on 2000-12-31 with total page 630 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is thirty years since the technique of high-yield preparation of isolated hepatocytes, by collagenase perfusion of the liver, was published. The original method described by Berry and Friend has undergone many minor modifications by other workers, and the two-step procedure introduced by Seglen in 1976 has become the most frequent way to prepare hepatocyte suspensions. An important development introduced by Bissell in 1973 was the use of the cells as the first step in monolayer culture. The availability of the isolated hepatocyte preparation as cells in suspension or culture has undoubtedly facilitated research on the liver. This was emphasised in our book, published (with Dr. Greg Barritt) in 1990, which described in detail methods of preparation and the properties of the isolated hepatocytes. It also discussed the usefulness of the preparation for the study of intermediary and xenobiotic metabolism, calcium ion transport, and the growth and differentiation of hepatocytes in culture. The book also touched briefly on a range of specialised techniques, including peri fusion, subcellular fractionation, transplantation, cryopreservation and measurement of intracellular pH. Although standard procedures for the manipulation of hepatocytes have not changed a great deal in ten years, they have undoubtedly been refined. This applies particularly to hepatocyte culture techniques, cryopreservation, and even to preparation of hepatocyte suspensions, where it is now feasible to use purified enzymes. There is also much more emphasis on the use and study of human hepatocytes, particularly in the field of pharmacology and therapeutics.
