Schematic representation of nuclear progesterone receptors A (PRA) and B (PRB) and membrane receptors PGRMC-1 and PGRMC-2 during the menstrual cycle in human endometrium. The dot density indicates the abundance of the represented molecule at each cycle phase and tissue compartment (glands or stroma), according to immunolocalisation (Bedaiwy et al., 2015; Keator et al., 2012; Mote et al., 1999), western blotting (Bedaiwy et al., 2015), real-time PCR and in situ hybridisation (Keator et al., 2012). Note, the maximal expression of PRA and PRB in the late proliferative phase (dotted rectangle) and the transient increase in stromal PRA expression at mid-secretory phase (dotted circle).
