In the April 9, 2008 issue's “This Week in the Journal” summary of the Development/Plasticity/Repair article by Coate et al., there was an error in the third sentence. The term “DP cells” should have been “EP cells.” Thus, the sentence should have read “This week, Coate et al. report that interactions between a type A ephrin (MsEphrin), which is expressed in some Manduca neurons [enteric plexus (EP) cells], and the MsEph receptor, which is expressed in midline cells, are required to prevent improper midline crossing by EP cells and axons.”
