Figure 1.
Morphometric calculation for villous capillarization (VC) and intervillous space (IvS) of placental villi. Calculation of VC was done by dividing the surface area of the capillary (blue outline) over the surface area of the villous (black outline). Calculation of IvS was done by subtracting the surface area of the photomicrograph (calculated by height {H} X width {W}; green outline indicated by black arrows) with the summed up area of all villous (black outline) within a particular photomicrograph. The surface area (mm2) of the respective capillaries and villous measured was generated by the software program. This slide was viewed at 20× magnification.
