Abstract
Phosphate-buffered sucrose
(PBSc) solution is effective for short-term hypothermic preservation of tissue during
feline kidney transplantation. A high-molecular-weight polyethylene glycol (35,000 Da,
PEG35) reportedly enhanced the protective effects against cold-induced tubular injuries in
animal kidney transplantation models. We investigated the ability of PBSc solution
containing PEG35 to preserve cultured feline kidney cells using in vitro
WST-8 cell proliferation assays. PEG35 significantly improved cell viability during 24 hr
of cold preservation. PBSc containing 20 g/l PEG35 achieved an effect
almost equal to that of University of Wisconsin (UW) solution, the gold standard
preservation solution used in human clinical kidney transplantation, for up to 24 hr of
preservation. Our results suggest that PBSc containing PEG35 provides an excellent medium
for graft cold storage during feline kidney transplantation.
