Figure 3

The expression of progesterone receptors in the male fetus at d75 gestation. (a) PGR transcript abundance in various fetal tissues in a control male fetus. (b) Immunolocalisation of PGR (brown–red arrow) to individual cells in a representative control male fetal pituitary at d75 gestation. (c) Immunolocalisation of PGR (brown) to Sertoli cells (yellow arrows) and fetal Leydig cells (red arrow) in a representative control fetal testis at d75 gestation. Scale bar = 50 µm.
