This book is the proceedings of a Falk Workshop held in Berlin, Germany, on January 23-24, 2003, which brought together experts in different fields of research to stimulate the transfer of findings from basic research to clinical application. Section I focuses on cell adhesion molecules of the liver and their role in hepatocarcinogenesis and inflammatory liver disease. Section II deals with infection and fibrosis and with transforming growth factor beta (TGF-beta). Morphogenesis, cell migration and inflammation are the subject of Section III with a focus on the role of integrins in blood cell-endothelial interactions. In Section IV the importance of cell adhesion molecules for cancer and their role as potential target for cancer therapy will be discussed.
