Selective stem-cell gene responses to higher-terahertz irradiation
The reported finding
Prolonged broadband exposure altered selected adipogenic/metabolic genes without broad heat-shock-gene activation.
Reading it carefully
Small replicate set; related Los Alamos publications share a research lineage. 2.52/10 THz are well above the 90–300 GHz research track; mechanistic context, not direct 6G evidence.
Inside the study
Technology connection
Higher-terahertz mechanistic context at 2.52/approximately 10 THz, outside the 90–300 GHz research band; not direct 6G evidence.
Publication type
Original journal research
Exposure conditions
Broadband pulses centred near 10 THz, about 1 mW/cm²; 2/9 h protocols. Comparison CW source: 2.52 THz, about 3 mW/cm². Temperature monitored.
Design & controls
Mouse mesenchymal stem-cell cultures; qPCR of selected differentiation and stress-response genes; non-irradiated controls.
Statistics
See reported finding and original tables; effect sizes not independently recalculated.
The protection question raised
Which exposure conditions and biological models reproduce this response, and what would establish its relevance to health?
