This book discusses the applications, outcomes and controversies of using animal models in cancer research and human disease. Topics include murine models of sporadic and inflammation-related colon carcinogenesis with particular focus on the AOM/DSS chemically induced colorectal cancer model; large animal models of human cardiovascular disease; developments of cell therapeutic strategies for Alzheimer's disease using animal models; the techniques and limitations of murine models of human colorectal cancer; animal models for antineoplastic chemotherapy-induced alopecia; and development of columnar-lined oesophagus with or without goblet cells in rate duodengastroesophageal reflux models through gut regenerative cell lineage (GRCL).
