| pubmed-article:21194950 | pubmed:abstractText | Asymmetric cell division drives the generation of differentiated cells and maintenance of stem cells. In budding yeast, autonomously replicating sequence (ARS) plasmids lacking centromere elements are asymmetrically segregated into the mother cell, where they are thought to contribute to cellular senescence. This phenomenon has been proposed to result from the active retention of plasmids through an interaction with nuclear pores. | lld:pubmed |
