Abstract: Progenitor cells have a considerable regenerative potential for damaged tissues. By utilizing these cells, vasculature or implant biocompatibility can be promoted. In this study we optimized the isolation protocol of bone marrow CD 117+ (ckit) progenitor cells. We differentiated CD1 17+ cells along an endothelial phenotype and tested their compatibility with various biomaterials. Biomaterials were compared for their proliferative properties using Laser Scanning Cytometry. We found the best endothelial progenitor cell growth on titanium and fibronectin coated porous aluminum oxide. These progenitor cell covered materials can be used to improve the function of future drug delivery systems or biosensors.
This is the first experimental protocol book that covers the differentiation of bone marrow-derived stem cells (BMSCs) into specific cell types, targeted at the undergraduate and graduate student level. The 19 chapters deal with the differentiation methods using small molecules, cytokines and polymeric scaffolds.BMSCs are pluripotential in that they not only act as myelo-regenerative and supportive cells, but can also differentiate into almost any kind of cells in our body. In addition, when implanted in vivo, they could help repair multiple tissues such as blood vessels, heart, liver and so on.For the differentiation of BMSCs, many methods have been introduced to adjust their microenvironment (chemical and physical cues), including chemical induction methods using large or small molecules and pellet culture; mechanical stimulation induction methods using cyclic mechano-transduction or ultrasonication; cytokine-released method using scaffolds; and so on.
Advances in Tissue Engineering is a unique volume and the first of its kind to bring together leading names in the field of tissue engineering and stem cell research. A relatively young science, tissue engineering can be seen in both scientific and sociological contexts and successes in the field are now leading to clinical reality. This book attempts to define the path from basic science to practical application. A contribution from the UK Stem Cell Bank and opinions of venture capitalists offer a variety of viewpoints, and exciting new areas of stem cell biology are highlighted. With over fifty stellar contributors, this book presents the most up-to-date information in this very topical and exciting field.
Tissue engineering integrates knowledge and tools from biological sciences and engineering for tissue regeneration. A challenge for tissue engineering is to identify appropriate cell sources. The recent advancement of stem cell biology provides enormous opportunities to engineer stem cells for tissue engineering. The impact of stem cell technology on tissue engineering will be revolutionary.This book covers state-of-the-art knowledge on the potential of stem cells for the regeneration of a wide range of tissues and organs, including cardiovascular, musculoskeletal, neurological and skin tissues. The technology platforms for studying and engineering stem cells, such as hydrogel and biomaterials development, microfluidics system and microscale patterning, are also illustrated. Regulatory challenges and quality control for clinical translation are also detailed. This book provides an comprehensive update on the advancement in the field of stem cells and regenerative medicine, and serves as a valuable resource for both researchers and students.
MSC (mesenchymal stem cells) have been reported to initiate revascularization after injury, to facilitate engraftment of blood-forming stem cells, and to reduce the incidence of graft-vs. host disease through their immune-suppressive qualities. Finally, bone marrow-derived MSC have been reported to home to areas of solid tumor revascularization, and thus may be used as delivery vehicles to target ablative agents into dividing tumor cells. Recently the characteristics of human MSC from adipose (fat) tissue have also been identified. The possibility of repairing tissues, speeding stem cell engraftment, and targeting solid tumors for specific killing, using MSC easily harvested from bone marrow, or better yet, from unwanted fat tissue, holds broad appeal, and is an intriguing possibility that could have dramatic effect on health care. This book has information on how to isolate, grow, and characterize MSC from marrow and fat, and gives important insight into how these cells may be used for gene delivery and cellular therapies in the future. Updates on emerging clinical trials are given.
Human pluripotent stem cells (hPSCs), which cover both human embryonic stem cells (hESCs) and induced pluripotent stem cells (iPSCs), show promise for drug discovery and regenerative medicine applications. These stem cells cannot be cultured on conventional tissue culture dishes but on biomaterials that have specific interactions with the hPSCs. Differentiation is regulated by the biological and physical cues conferred by the biomaterial. This book provides a systematic treatment of these topics bridging the gap between fundamental biomaterials research of stem cells and their use in clinical trials. The author looks at hPSC culture on a range of biomaterial substrates. Differentiation and control of hESCs and iPSCs into cardiomyocytes, osteoblasts, neural lineages and hepatocytes are covered. The author then considers their translation into stem cell therapies and looks at clinical trials across spinal cord injury, macular degeneration, bone disease and myocardial infarction. Finally, a chapter on future directions closes the book. By using this book, the reader will gain a robust overview of current research and a clearer understanding of the status of clinical trials for stem cell therapies.
In Situ Tissue Regeneration: Host Cell Recruitment and Biomaterial Design explores the body's ability to mobilize endogenous stem cells to the site of injury and details the latest strategies developed for inducing and supporting the body's own regenerating capacity. From the perspective of regenerative medicine and tissue engineering, this book describes the mechanism of host cell recruitment, cell sourcing, cellular and molecular roles in cell differentiation, navigational cues and niche signals, and a tissue-specific smart biomaterial system that can be applied to a wide range of therapies. The work is divided into four sections to provide a thorough overview and helpful hints for future discoveries: endogenous cell sources; biochemical and physical cues; smart biomaterial development; and applications. - Explores the body's ability to mobilize endogenous stem cells to the site of injury - Details the latest strategies developed for inducing and supporting the body's own regenerating capacity - Presents smart biomaterials in cell-based tissue engineering applications—from the cell level to applications—in the first unified volume - Features chapter authors and editors who are authorities in this emerging field - Prioritizes a discussion of the future direction of smart biomaterials for in situ tissue regeneration, which will affect an emerging and lucrative industry
