In this study, we assessed the genetic integrity of over 400 samples of human multipotent
stem cells using gene expression data sets. Our analysis reveals that neural and
mesenchymal stem cells acquire characteristic large chromosomal aberrations at a similar,
or somewhat lower, frequency to that seen in pluripotent stem cells, sometimes within a few
passages in culture. Some of the identified chromosomal abnormalities can also be detected
in human tumors of the respective tissues.
