a The rats were exposed to either a soy isoflavone-free diet (Phyto-free) or a soy isoflavone-rich diet (Phyto-600) from conception until 150 days of age (n = 5 per diet treatment group).

b Incidence of apoptosis was expressed as the percentage of apoptotic cell number over total cell number in AVPV.

^ Significantly greater apoptotic cell number or incidence of apoptosis in the Phyto-600 AVPV compared to the Phyto-free group (p < 0.05; two sample student t-test).
