Figure 4From: Steroidogenic capacity of the placenta as a supplemental source of progesterone during pregnancy in domestic cats3β-HSD -mRNA expression in pseudopregnant and pregnant CLs (upper panel) and placentas (lower panel). Letters “a, b” indicate statistical differences within pseudopregnancy (P < 0.05). Letters “x, y” indicate statistical differences within pregnancy (P < 0.01). Asterisks indicate statistical differences between 3β-HSD-mRNA levels during the course of pseudopregnancy and pregnancy (***P < 0.001).Back to article page
