The drug as well as the physical contact of the microneedles with the scar tissue contributes to the efficacy of the device, leading to the cessation of scar tissue
growth and a
considerable reduction of keloids as
demonstrated in laboratory cultures and experiments with animals.
Considerable previous research in cell cultures has
demonstrated that low doses of ionizing radiation results in «bystander» effects, in which nearby, unexposed tissues suffer cell death, mutations, and tumor - inducing
growth (ScienceNOW, 7 September 2005).
