  "summary": "This in vitro study exposed dermal fibroblast cells to electromagnetic fields with varying intensities and durations. Lowering intensity from 2 mT to 1 mT was reported to increase cell frequency over 24–72 hours, whereas raising intensity from 3 mT to 4 mT was reported to decrease cell frequency at 48–72 hours. The authors propose that specific exposure settings might be used non-invasively to support wound healing or to inhibit growth relevant to skin cancer treatment, though these applications are not directly demonstrated in the abstract.",

    "Increasing intensity from 3 mT to 4 mT was associated with decreased reported cell frequency at 48 and 72 hours.",
    "The abstract suggests potential therapeutic optimization for wound/skin lesion restoration using lower intensity and longer exposure.",
    "The abstract suggests potential non-invasive approaches for skin cancer treatment using higher intensity and longer exposure.",

The authors suggest potential non-invasive therapeutic applications, though important exposure and measurement details are not provided in the abstract.",
    "linkedin": "This in vitro paper reports intensity- and time-dependent changes in dermal fibroblast cell frequency under EMF exposure: lower intensity (2→1 mT) was associated with increased frequency over 24–72h, while higher intensity (3→4 mT) was associated with decreased frequency over 48–72h. The abstract proposes potential therapeutic optimization, but lacks key methodological details (e.g., EMF frequency/waveform and measurement methods)."
