In 1996, we organized a workshop, inter alia, at the National Research Co- cil in Milan under the generous sponsorship of the European Science Foun- tion. On that occasion, a small group of investigators convened from many countries and presented early evidence of the possibility of assembling basic units of mammalian chromosomes into artificial constructs (or, indeed, red- ing the relevant components to more manageable dimensions and defined c- stitution). Progress in the following years has been slow but steady. Many scientists who took part in the workshop have since been engaged in active...
