Mammalian artificial chromosomes--vectors for somatic gene therapy

Abstract

Mammalian artificial chromosomes might prove to be useful vectors for somatic gene therapy. The functional elements of such an artificial chromosome are telomeres, a centromere and a replication origin. Recent progress in the characterization of these functional elements of the eukaryotic chromosome will be described. Attempts to construct artificial chromosomes for mammalian cells and their use for somatic gene therapy are discussed.
