CELL BIOLOGY. For the article “Molecular characterization of lymphatic endothelial cells,” by Simona Podgrabinska, Pascal Braun, Paula Velasco, Bryan Kloos, Michael S. Pepper, David G. Jackson, and Mihaela Skobe, which appeared in number 25, December 10, 2002, of Proc. Natl. Acad. Sci. USA (99, 16069–16074; First Published November 22, 2002; 10.1073/pnas.242401399), the authors note “In the Results, we have erroneously stated that the sequence for Prox-1 (GenBank accession no. U44060) was not present on the Affymetrix GeneChip, although we have listed it in the Table 1, which was published as supporting information on the PNAS web site. As indicated in the Results, the sequence encoding podoplanin (GenBank accession no. AF390106) was not present on the GeneChip. However, two sequences with 96% homology to podoplanin were present under the different name, i.e., lung type-I cell membrane-associated proteins hT1a-1 and hT1a-2 (GenBank accession nos. AF030427 and AF030428, respectively). Dr. David G. Jackson does not wish to be included as a coauthor but is instead acknowledged for providing the LYVE-1 polyclonal antibody. In addition, the legend of Fig. 1 should have included the credit ‘Reprinted with permission from the Journal of Investigative Dermatology,’ because the upper panels from Fig. 1 were previously published in ref. 7.” These corrections do not affect the conclusions of the article.
