The effect of Wi-Fi on elastic and collagen fibres in the blood vessel wall of the chorioallantoic membrane
This animal experimental study exposed chicken embryos (CAM) continuously to 2.4 GHz Wi-Fi at an average power density of 300 μW/m2 for 9 or 14 embryonic days. H&E staining reportedly showed no significant structural differences in large vessel walls versus controls. However, special staining reported decreased optical density of elastic fibers at both time points and changes in collagen fiber optical density (increase at day 9, decrease at day 14). The authors conclude Wi-Fi exposure can alter fibrous vessel wall components and suggest potential relevance to cardiovascular disorders.
Key points
- Chicken embryo CAM vessels were exposed continuously (24 h/day) to 2.4 GHz Wi-Fi at 300 μW/m2 for 9 or 14 days.
- H&E staining reportedly did not reveal significant structural differences in large vessel walls between exposed and control groups.
- Special staining reported a significant decrease in elastic fiber optical density at day 9 and day 14 with Wi-Fi exposure.
- Collagen fiber optical density reportedly increased at day 9 but decreased by day 14 in exposed embryos compared with controls.
- The study interprets these fiber changes as an altered balance/composition of vessel wall components.
- The abstract frames the findings as potentially relevant to cardiovascular disorder development.
