Figure 3.
Randomly selected representative photographs of immunodetection of 17β-hydroxysteroid dehydrogenase (17βHSD) in porcine myometrium of pigs during the peri-implantation period exposed in vitro to an electromagnetic field (EMF) at 50 and 120 Hz for 2 and 4 h in the presence or absence of P4. The panels show representative 17βHSD signal (A), negative control (B), and 17βHSD signal in EMF-treated myometrial slices (merged) (C). Magnification 400×. CM—circular muscle; LM—longitudinal muscle. The nuclei are stained with DAPI (blue) and binding sites are visualized with Alexa Fluor 555 (red).
