Molecular hydrogen enhances osteogenesis in Danio rerio embryos

Molecular hydrogen (H2) has been reported to have important biological effects on bone tissue in several in vitro and in vivo models. Danio rerio (zebrafish) embryo is a good model to study osteogenesis because its transparency, size and rapid development. In zebrafish embryo, hydrogen rich water (HRW) do not affect vitality or growth rate up to 15%. In addition, 7% HRW treatment enhances zebrafish embryo osteogenesis increasing vertebral mineralization rate. In conclusion, we demonstrated the beneficial effects of hydrogen on anabolic bone functions in vivo.
