Fig. 2. Validation of 15 differentially expressed genes by quantitative real-time polymerase chain reaction. Three genes were up-regulated (green bar) and 12 were down-regulated (blue bar) in the non-balding scalp. Thirteen genes showed statistical significance (p-value<0.05); the exceptions were SOX21 and PTGDS. (**p<0.01, and ***p<0.001).
