The European Collection of Cell Cultures (ECACC) has advised that multiplex analysis of the cell line deposited with them in 2006 and described by Patel et al. shows an identical match to that of the JEG3 cell line. ECACC used a new set of PCR (forensic) primers to detect this coidentity, which initial analyses by ECACC had not uncovered. The JEG3 cell line was derived from a human choriocarcinoma, and the cell-conditioned medium from this line was used to support the growth of the putative endothelial cell line. ECACC has withdrawn this cell line, known as TEC61, from distribution. No early-passage cells exist, so it is not possible to determine when cross-contamination occurred. Since the overall premise and conclusions of the paper can no longer be assured, the authors would like to retract the paper. We sincerely apologize to the Editorial Board and readership of the American Journal of Physiology.
