This in vitro study reports that radiofrequency (RF) exposure in the 800–2,400 MHz range modulates differentiation pathways in human cortical organoids derived from embryonic stem cells. RF exposure is described as maintaining radial glia stem cell identity and delaying differentiation, alongside induction of endogenous retrovirus expression and increased expression of ASD-associated genes and retroelements. The abstract attributes these effects to dysregulation of BET proteins and reports that BET inhibition rescues the RF-associated developmental defects.

This animal and in vitro study examined non-thermal 900 MHz RF-EMF exposure during prenatal and postnatal development at 0.08 and 0.4 W/kg SAR. The authors report changes consistent with altered neurodevelopment, including reduced BDNF, reduced in vivo cell proliferation, and disrupted synaptic balance in rat pup brain regions. In vitro, exposed neural stem cells showed increased apoptosis and DNA double-strand breaks and shifts in cell populations toward glial lineages. The authors conclude that regulatory-level 900 MHz exposure can disrupt key neurodevelopmental processes in rodents.
