Hua Tian, Toyoaki Tenzen and Andrew P. McMahon Development 131, 4021-4033.
A re-examination within our laboratory of two papers published by our group
in Development (Tian et al.,
2004
; Tian et al.,
2005) has revealed a duplication of Dr Tian's data in these
papers. On review, we have found that the documentation underpinning a number
of conclusions in Tian et al.,
2004 is inadequate. As a consequence, we regret that we must
retract Tian et al., 2004.
The principal conclusions in Tian et
al., 2005 are supported by appropriate documentation.
Nevertheless, to confirm the conclusions drawn from Dr Tian's primary data on
the tissue requirement for Dispatched in facial development, we will repeat
the experiments documented in Figure 2 of
Tian et al., 2005, and will
report our findings to the journal once these experiments have been concluded.
We do not expect this re-analysis to change the conclusions drawn in this
paper.
We apologize to the editors and readership of Development.
