Corpus luteum vascularization. Blood Vessels/capillaries mean at seven, 15, 30, 45, 60 and 90 gestational ages in corpus luteum of pregnant sows. Different letters represent significant differences between the averages of blood vessels/capillaries number in corpus luteum by Tukey test (P = 0.05).

Expression of apoptotic genes. Fold change of (a) BAX, (c) BCL2 and (e) CASP3 expression in corpus luteum across gestational ages of local Piau breed (LPB) and Commercial line (COM). Fold change of (b) BAX, (d) BCL2 and (f) CASP3 expression between genetics groups (COM and LPB) throughout pregnancy. *P = 0.05.

6. Fig. 5
Heatmap of corpus luteum angiogenesis and apoptosis. Heatmap of (a) angiogenic and (b) apoptotic genes in Commercial (COM) and Piau (LPB) corpus luteum during pregnancy. Unsupervised hierarchical clustering of angiogenic and apoptotic differentially expressed genes across six gestational ages (7, 15, 30, 45, 60 and 90 days of pregnancy). Angiogenic genes were divided in five groups by similar expression pattern. Apoptotic genes were clustered in only one group by similar expression pattern. A median expression value equals to zero was designated in gray; black means reduced expression and white increased expression.
