Stimulus-triggered Acquisition of Pluripotency

Is STAP Real?

  • RIKEN Panel Finds Misconduct in Reprogrammed Stem Cell Papers Science April 2014 |
  • Japanese research institute has opened an investigation into this groundbreaking stem cell study after concerns were raised about its credibility. The RIKEN investigation follows allegations on blog sites about the use of duplicated images in Obokata’s papers, and numerous failed attempts to replicate her results. Nature

This work has now been discredited

This is a good example of one of the basic principles of scientific research, that is: Someone else must be able to reproduce your experimental results.
