In the report “Nucleotide structure of equine platelet-derived growth factor-A and -B expression in horses with induced acute tendinitis,” published July 2006 (Am J Vet Res 2006;67:1218–1225), the legend for Figure 3 on page 1221 is incorrect. Figure 3 represents the complete coding sequence for the equine PDGF-B prepropeptide and human, mouse, and rat BDGF-B sequences.
