Infos

Cancer stem cells have originally been identified in leukemia and later in several solid tumor types. They have very different properties from the bulk of the tumor as they divide much more slowly and have very efficient drug resistance mechanisms. Current treatments might largely spare cancer stem cells. This book looks at recent developments in the field of cancer stem cells and the possible impact for the identification of novel treatment paradigms for cancer.
