Aging of mesenchymal stem cell in vitro

Abstract excerpt

BACKGROUND: A hot new topic in medical treatment is the use of mesenchymal stem cells (MSC) in therapy. The low frequency of this subpopulation of stem cells in bone marrow (BM) necessitates their in vitro expansion prior to clinical use. We evaluated the effect of long term culture on the senescence of these cells. RESULTS: The mean long term culture was 118 days and the mean passage number was 9. The average...
