Figure S4. No differences in p63 expression between Terc^–/– and G3 Terc^+/–* tail skin. (A) Percentage of p63-positive cells in the basal and suprabasal IFE layers of the tail skin from mice of the indicated genotypes, which have been treated (+TPA) or not (control) with TPA. (B) Number of p63-positive skin layers in mice of the indicated genotype that have been treated (+TPA) or not (control) with TPA. Note that TPA treatment provokes a similar increase in the number of p63-positive layers in both genotypes. (C) Representative examples of p63-positive cells in mice of the indicated genotypes, which have been treated (+TPA) or not (control) with TPA. Arrows indicate the basal and suprabasal IFE layers.
