Fig. 2.

Effect of STZ treatment and age on urinary bladder hypertrophy and distension. a, the effect of STZ treatment on the wet weight of urinary bladders from different treatment groups is shown. Mean values ± S.E.M. are shown. Each group contained three to six mice. b, the weight of urinary bladder from wild-type (n = 27) and M₂ KO (n = 22) mice is plotted against age. c, the average length and width of urinary bladders immediately after euthanization of wild-type (n = 5) and M₂ KO (n = 6) mice at 7 months of age are shown.
