Figure 6.

Effect of hormones on glycogen production in the VEC-FT tissues. PAS stained cross-sections of tissues treated with: (A) no hormone (control), (B) E₂ (100 nmol/L), and (C) progesterone (100 nmol/L) are shown. Periodic Acid–Schiff (PAS) stains glycogen reddish-pink. Glycogen was observed in all tissues, increasing in amount as the apical surface is approached. Estradiol treated tissues had the highest glycogen content as evidenced by more intense staining in the suprabasal cell layers. Basal cells showed little or no staining.
