Catherine Verfaillie Under Scrutiny For Erroneous Duplication of Data
Known for her seminal work with multipotent adult progenitor cells
(MAPC), former University of Minnesota stem cell researcher Catherine
Verfaillie is the subject of an ongoing investigation into the validity
of specific data duplicated in two different journals. Flow cytomety
data reproduced in articles from both Nature and the Journal of
Experimental Hematology in 2002 are the subject of hot debate. At the
epicenter lies skeptical experts who question whether the duplication
was an "honest error" as a 3 person UMN panel concluded, or could the
data possibly be unreliable, in which case stem cell experts are split
on whether they believe the erroneous data affects the overall
interpretation and conclusions of the original article. Verfaille
replied, "I personally don't think it affects the conclusion of the
paper, and I've spoken to many people who personally don't think so,"
but it is "up to Nature to decide." Currently, Nature
is investigating the data more thoroughly to determine if they believe
further actions are necessary. Read more in News of the Week from Science/AAAS -DR Wakeman
