Abstract

Overview

Terahertz (THz) radiation, with a wavelength range of 30-3000 μm and frequency of 0.1-10 THz, is increasingly utilized across various applications due to advancements in THz sources and devices.

Findings

  • The study focuses on the impacts of THz radiation on human and mouse neural stem cells (hNSCs and mNSCs).
  • It investigates how THz irradiation time and power affect cell proliferation, apoptosis, and DNA damage.
  • Assessment methods include flow cytometry and immunofluorescence.
  • Results indicate that cell responses are dose-dependent, with hNSCs showing greater vulnerability under identical conditions compared to mNSCs.

Conclusion

This research highlights that THz radiation significantly affects neural stem cell behavior, necessitating caution and further studies on its biological impacts.
