Stem cell researchers should pay close attention to this incidence and really carefully re-assess the risks associated with their planned cell therapy.
If a "normal" stem cell could "mis-develope" into a tumor, then the likelihood of oncogene-induced and virus-integrated iPS cells would be more likely to contribute to tumor formation in human if put into clinic trials. Already all iPS cells have shown tumor formation in animals. However, some iPS cell researchers would even characterize these cells as "cancer-free" "safe" iPS cells. Amazing. See more detalied at .

Competing interests declared: I am an off-career-duty professionally-educated and hands-on trained life scientist ( I am CEO of Truthfinding Cyberpress and editor-in-chief of its journals such as Logical Biology, Pioneer, Scientific Ethics, Top Watch, and International Medicine ( ) . I am the director of my life-time self-supporting research institute The Eagle Institute of Molecular Medicine. However, I have no financial interest in writing this response. The only competition is to compare my unique view on stem cells ( ) and their intrinsic aging ( ) with mainstream views and to introduce my perspective on cloning ( ). But that was all aimed at increasing scientific understanding of the issues.
