Figure S2. Similar proliferation rates in G3 Terc–/– and G3 Terc+/–* tail skin. (A) Percentage of Ki67-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. Note a similar increase in Ki67-positive cells after TPA treatment in both genotypes. (B) Representative examples of Ki67-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.
