RETRACTED: Contribution of the PI3K/Akt/PKB signal pathway to maintenance of self‐renewal in human embryonic stem cells

Abstract
Reason: upon re‐examination of their work, the authors have found that the data in Figure 2A was intentionally fabricated (the blots of the 3rd and 4th rows are duplicated and are mirror images). As a result, the authors have elected to withdraw the complete article with apologies to the scientific community.
