The abstract makes no mention of -130°C, but digging into the actual paper (can be read here: www.21cm.com/pdfs/cryopreservation_advances.pdf), it does mention: "Fig. 13. Confinement of ice formation to the pelvis of a rabbit kidney that was perfused with M22 at 22°C for 25min, bisected, and allowed to passively cool in air in a CryoStar freezer at about 130°C... The vast majority of the kidney appears to have vitrified and is indistinguishable from the appearance of the kidney prior to cooling." (Emphasis mine)
