Regulation of CD2AP expression is growth-mode specific. A, Regulation of CD2AP mRNA levels after sciatic nerve crush. Samples are L4/L5 whole DRG homogenates. Control values were set to 1. Contra, Contralateral; Ipsi, ipsilateral. *Statistically significant compared with contra (multivariate ANOVA, post hoc t test). B, CD2AP mRNA expression during postnatal development. By convention, the lowest expression condition for each tissue sample was set to 1. Samples are whole tissue homogenates. *Statistically significant changes (ANOVA and post hoc t test).
