Chemoprevention of cancer has been the focus of intensive research for more than two decades. Epidemiological evidence has shown a small, but significant association between fruit and vegetable intake and a reduction in cancer risk. Diet may account for about thirty five percent of cancer. Large claims have been made for the effectiveness of particular diets in determining one's risk of developing cancer, ranging from protection against cancer initiation, progression and metastasis. A wide array of dietary components has been demonstrated to be as effective in fighting off cancer. Towards an...

The main objective of this book is to provide a comprehensive review on stem cells and their role in tissue regeneration, homeostasis and therapy. In addition, the role of cancer stem cells in cancer initiation, progression and drug resistance are discussed. The cell signaling pathways and microRNA regulating stem cell self-renewal, tissue homeostasis and drug resistance are also mentioned. Overall, these reviews will provide a new understanding of the influence of stem cells in tissue regeneration, disease regulation, therapy and drug resistance in several human diseases.
