Retraction Note: PEDF inhibits VEGF- and EPO- induced angiogenesis in retinal endothelial cells through interruption of PI3K/Akt phosphorylation

This is an excerpt from the content

Retraction to: Angiogenesis DOI 10.1007/s10456-009-9153-5

This article has been retracted at the request of the Editors as it contains manipulated figures.

In Fig. 4, paper photomicrographs are supposed to represent images of endothelial cell cultures after scratching the monolayer in order to assess migration of the cells. However, the panels do not represent independent data, but instead contain repetitive cell patterns suggestive of digital manipulation of these figures.

As such, this article represents a severe abuse of the scientific publishing system. The scientific community and the Editors take a very strong view on this matter, and apologies are offered to readers of the journal that this problem was not detected during the submission and review process.

It has been found that other articles from the same laboratory also contain manipulated figures. We have listed those articles below.
