Fold changes of gene expression in unpigmented hair follicles compared with pigmented hair follicles (qRT-PCR array analysis was performed on one subject).

*↑: up-regulation; ↓: down = regulation; W: unpigmented hair follicle (HF); B: pigmented HF.*↑: 上调（up-regulation）；↓: 下调（down-regulation）；W: 无色素毛囊（unpigmented hair follicle, HF）；B: 有色素毛囊（pigmented HF）。
