In the article “Two Distinct Subpopulations of Nestin-Positive Cells in Adult Mouse Dentate Gyrus,” by Satoshi Fukuda, Fusao Kato, Yusuke Tozuka, Masahiro Yamaguchi, Yusei Miyamoto, and Tatsuhiro Hisatsune, which appeared on pages 9357-9366 of the October 15, 2003 issue, the authors would like to add the citation of the related work by Filippov et al. [Filippov V, Kronenberg G, Pivneva T, Reuter K, Steiner B, Wang LP, Yamaguchi M, Kettenmann H, Kempermann G (2003) Subpopulation of nestin-expressing progenitor cells in the adult murine hippocampus shows electrophysiological and morphological characteristics of astrocytes. Mol Cell Neurosci 22:373-382], which was published during the revision of the article. They have also classified nestin-expressing cells in the adult hippocampal dentate gyrus based on the difference in their morphological and electrophysiological properties.
