Corrections: In the article “Netrin-3, a mouse homolog of human NTN2L, is highly expressed in sensory ganglia and shows differential binding to netrin receptors” by H. Wang, N. G. Copeland, D. J. Gilbert, N. A. Jenkins, and M. Tessier-Lavigne, which appeared on pages 4938–4947 of the June 15, 1999 issue, the following corrections should be made. On page 4939, in Figure 1, “mouse netrin-2” should read “mouse netrin-3.” In Figure 1 legend, “GenBank accession number: AF152418” should be added at the end of the legend. In the first sentences on page 4944 and in Figure 9 legend on page 4946, “120 μg/ml” should read “120 ng/ml.”
