Handbook of Nanotoxicology, Nanomedicine and Stem Cell Use in Toxicology

Nanotoxicology is the study of the toxicity of nanomaterials. Because of quantum size effects and large surface area to volume ratio, nanomaterials have unique properties compared with their larger counterparts. Nanomedicine is the medical application of nanotechnology. nanomedicine ranges from the medical applications of nanomaterials, to nanoelectronic biosensors, and even possible future applications of molecular nanotechnology. The book "Handbook of Nanotoxicology, Nanomedicine and Stem Cell use in Toxicology" is consists of ten chapters. Cancer stem cells are defined as cancer cells that show the two properties of stemness that is unlimited self-renewal and, pluripotency or multipotency, which are broadly discussed in first chapter. In second chapter, we focus on the differentiation of ESCs into the ectodermal lineage and on the two in 2012 ongoing clinical trials involving transplantation of ESCs derivate into eye and spinal cord. We introduce the clarification for the progress and drawbacks of current cardiac stem cell therapy in third chapter. It finally indicates the future directions of cardiac cell therapy through our recent researchers combining PSCs and cell sheet technology. Induced pluripotent stem (iPS) cells are somatic cells which have been imbued with pluripotent differentiation potential through some form of artificial treatment in fourth chapter. We review studies that have examinied the epigenetic instability of ES cells during generation and maintenance cultures, and discuss the candidate factors that may be responsible for this epigenetic instability in fifth chapter. Crucial ignored parameters on nanotoxicology have been introduced in sixth chapter. Stem cell predictive hemotoxicology has been discussed in seventh chapter. In eight chapter, we introduce an exogenous regulators into embryonic stem cells. The application of embryonic stem (ES) cells to research and therapy has been a landmark development in science. The purpose of ninth chapter is in threefold: first, to examine the medical issues surrounding the cryopreservation of frozen embryos; second, to give an ethical analysis of the arguments for and against allowing to die: and thurd, to give recommendations on how to avoid the continuation of this problem in the future. Last chapter focuses on challenges and possibilities of embryonic stem cells for therapies. The successful establishment of human embryonic stem cells (HESCs) in culture has raised unprecedented public interest and expectation of treating intractable diseases such as diabetes, spinal cord injuries, neurodegenerative and cardiovascular diseases.
