Figure 3. Identification of macro-environmental modulators following hair plucking.
(A) TUNEL assay to measure apoptosis. (B) Real time PCR from extra-follicular macro-environmental tissues revealed the kinetics of gene expression induced by plucking (Normalized to GAPDH with 40 cycles, data are represented as mean +/− S.D., n=3).
(C) Whole mount in situ hybridization showed that Tnf-α is markedly up-regulated in the inter-follicular area beginning 2 days after wax stripping. See also Figure S3, S4.
