CD157 and CD38 mRNA expression in the brain. a Schematic drawing of the time course of mRNA expression in the whole brains of pups on postnatal days 1, 7, and 14. One hundred percent refers to values on postnatal days 1 or 14 for CD157 and CD38, respectively. Data for CD157 and CD38 were obtained from previous reports by Lopatina et al. [42] and Higashida et al. [45], respectively (n = 5 mice for CD157 and n = 4 mice for CD38). b Quantitative data obtained by RT-PCR analysis of CD157 and CD38 mRNA expression in four brain regions of adult male mice using β-actin mRNA as an internal control. Values show percentages of means  ±  S.E.M. (n  =  5 independent experiments) of CD157/actin with values in the spleen set to 100. One-way ANOVA reveals F _2,40 = 195.94, P < 0.0001 for CD157 and P < 0.0001, F _4,20 = 9.78 for CD38. Significant from density of spleen at *P < 0.0001, ^## P < 0.001, ^# P < 0.05, respectively.
