Sublethal high hydrostatic pressure (HHP) treatment of cells was reported to enhance stress tolerance and to increase post-thawing survival after cryopreservation in mouse, swine and cattle. The goal of this study was to define if HHP stress tolerance depends on the embryos' stage of development and culture conditions, to describe long term in vivo effects and transcriptional alterations of selected stress related genes. Studies showed that impacts greater than 60 MPa caused blastomere and membrane injuries to the two-cell stage embryos, while even 80 MPa was well tolerated by blastocysts. HHP treatment caused significant upregulation of Azin1, Sod2 and Gadd45g genes, detected by RT-qPCR. The transfer of HHP treated blastocysts revealed normal in vivo development and reproductive function in a two generation study. The cell type and the embryos' development stage shall be taken into account when optimizing sublethal HHP stress treatment protocol of different cells.
