This book brings together the papers presented to the VI International Meeting on the Human Genome Project: Transplants and Human Cloning in the Twenty-first Century, held at the Valencia seat of the Universidad Internacional Menéndez Pelayo (UIMP).

It prolongs a line of discussion opened up by the BBVA Foundation several years back, to promote a deeper knowledge of the latest advances in genetics: on this occasion, in the field of xenotransplants and tissue and organ cloning, two of the crucial scientific-technical challenges of the 21st century with enormous social and health potential. Its publication marks a new addition to the Foundation’s ample stocks on this subject area.
