Figure 3. Regulation of gross ovine placental morphology.

A meta-analysis of the percentage of the total placentome number classified as everted C/D type placentomes in single fetuses with respect to gestational age (term 145–150 days) in normal nutritional conditions (control, ▵) and after either undernutrition earlier in gestation (▴) or cortisol exposure for 5–10 days before delivery (). Dashed lines connect control and experimental data from the individual studies. Data from Alexander (1964); Vatnick et al. (1991); Tangalakis et al. (1995); Heasman et al. 1998; Penninga & Longo (1998); Steyn et al. 2001; Gardner et al. 2002; Osgerby et al. 2004; Ward et al. (2006).
