# Hydrogen Treatment Protects against Cell Death and Senescence Induced by Oxidative Damage.
> 酸化ダメージによる細胞死と老化に対する水素処理の保護効果


## Abstract

This in vitro study examined the capacity of nanoparticle hydrogen-containing water to counteract oxidative damage in murine embryonic fibroblasts derived from C57BL/6 mouse embryos at day 12.5. Unlike conventional hydrogen micro- or macroparticles, nanoparticle hydrogen maintains stability in water over extended periods. Hydroxyurea was used to induce ROS production and accelerate cellular senescence. Daily exposure to hydrogen water suppressed ROS accumulation, reduced cytotoxicity, inhibited β-galactosidase accumulation in the cytoplasm (a senescence marker), and prevented the formation of abnormal nuclei, while also promoting cell proliferation. These protective effects were particularly pronounced under conditions of accelerated oxidative stress. The findings indicate that nanoparticle hydrogen water exhibits both antioxidant and anti-senescence properties in this cell model.

### Mechanism

Nanoparticle hydrogen water scavenges reactive oxygen species, thereby suppressing senescence markers such as β-galactosidase accumulation and abnormal nuclear morphology, while preserving cell proliferative capacity under oxidative stress conditions.

## Delivery context

This is basic research at the cellular or molecular level. For human application, inhalation is the most promising delivery route, but inhalation carries explosion risk and concentration matters (empirical LFL of 10%; high-concentration devices are not recommended).

## Safety notes
