In the article “Platelet-Derived Growth Factor Receptor-β Constitutive Activity Promotes Angiogenesis In Vivo and In Vitro” by Magnusson et al that appeared in the October 2007 issue of the journal (Arterioscler Thromb Vasc Biol. 2007;27:2142–2149), in the Results section on page 2143, under The D849V Mutation Confers Increased PDGFR-β Kinase Activity In Vitro, the first sentence is missing a reference. The reference is: Jakobsson L, Kreuger J, Claesson-Welsh L. Bldg blood vessels-stem cell models in vascular biology. J Cell Biol. 2007;177:751–755. This should have also been added to the reference list at the end of the article.
Also on page 2146, in the discussion section a reference should have been added in place of “(Looman et al).” The reference is: Looman C, Sun T, Yu Y, Zieba A, Ahgren A, Feinstein R, Forsberg H, Helberg C, Heldin CH, Zhang XQ, Forsberg-Nilsson K, Khoo N, Fundele R, Heuchel R. An activating mutation in the PDGF receptor-β causes abnormal morphology in the mouse placenta. Int J Dev Biol. 2007;51:361–370. This should have also been added to the reference list at the end of the article.
These errors have been corrected in the online version of the article. The publisher regrets the oversight.
