title: Chromosomal engineering.
abstract: Artificial chromosomes (ACs) are engineered chromosomes with defined genetic contents that can function as non-integrating vectors with large carrying capacity and stability. The large carrying capacity allows the engineering of ACs with multiple copies of the same transgene, gene complexes, and to include regulatory elements necessary for the regulated expression of transgene(s). Artificial chromosome based systems are composed of AC engineered to harbor and express gene(s) of interest and an appropriate recombination system for 'custom' engineering of ACs. These systems have the potential to become an efficient tool in diverse gene technology applications such as cellular protein manufacturing, transgenic animal production, and ultimately gene therapy. Recent advances in artificial chromosome technologies outline the value of these systems and justify the future research efforts to overcome the obstacles in exploring their full capabilities.
