Cell Contact Accelerates Replicative Senescence of Human Mesenchymal Stem Cells Independent of Telomere Shortening and p53 Activation: Roles of Ras and Oxidative Stress

1 Aug 2011

Abstract excerpt

Mesenchymal stem cells (MSCs) are of great therapeutic potentials due to their multilineage differentiation capabilities. Before transplantation, in vitro culture expansion of MSCs is necessary to get desired cell number. We observed that cell contact accelerated replicative senescence during such process. To confirm the finding as well as to investigate the underlying mechanisms, we cultured both human bone...
