Abstract excerpt
Cultured human umbilical cord mesenchymal stem cells (hUC-MSCs) are being tested in several clinical trials and encouraging outcomes have been observed. To determine whether in vitro expansion influences the genomic stability of hUC-MSCs, we maintained nine hUC-MSC clones in long-term culture and comparatively analyzed them at early and late passages. All of the clones senesced in culture, exhibiting decreased...
