A Wnt-er’s tale: Blood pulls second signaling paper from Spanish scientists over image fakery

Blood has pulled a paper 2007 paper from a group of Spanish researchers, one of whom appears to have been manipulating images.

The group’s work became the focus of expressions of concern from the Journal of Clinical Oncology this spring and in 2010.
