Tammar SLC22A3 localised at the placental endodermal cells. A An example of the early tammar fetus and placenta. Schematic diagram below the photo represents tammar placental structure and placental cell types. While the bilaminar omphalopleure (BOM) is the non-vascularised part of placenta, the trilaminar omphalopleure (TOM) is the vascularised part of placenta. The sinus terminalis (ST) is the blood vessel that marks the boundary between the vascular and non-vascular regions, BOM and TOM contains trophoblast cells (Tr) and endodermal cells (En). The mesodermal (Me) layer of TOM has red blood cells (RBC) in the developing blood vessels. B Immunofluorescence with IgG negative control. C Immunofluorescence of SLC22A3 in BOM placenta tissue. D Immunofluorescence of SLC22A3 in TOM placenta tissue. Red and blue colours represent SLC22A3 and DAPI staining, respectively. Right-hand side panels show high power photos. Scale bars: 100 μm and 40 μm (high power and low power) panels. Endo: endometrium
