No misconduct found in the VSELs papers

In November 2020 I wrote about a set of 28 papers published by Mariusz Ratajczak, a professor at the University of Louisville who works on VSELs, very small embryonic-like stem cells.

Most of these papers included reused images, presented as new experiments without proper citation, while some others appeared to show overlapping photos or duplicated elements within the same photo. You can read my 2020 blog post here.

I shared my concerns about these papers with the university in February 2019.

The University of Louisville found there was no research misconduct. The institution followed its established, thorough, and robust process and made no findings of research misconduct against Dr. Ratajczak associated with any of the allegations, including all the allegations that continue to persist publicly on the internet.
