Melbourne scientists say they've made a discovery that could lead to organ transplant waitlists becoming a problem of the past.

The group of RMIT University researchers took the first step towards improved storage of human cells using cryo-freezing, which may lead to the safe storage of organs via cooling biological specimens down to very low temperatures, so they can be stored for long periods of time.

RMIT University lead researcher Dr Saffron Bryant told 6PR Mornings the finding could lead to the development of tailor-made cryoprotective agents, which could target specific cell types and help keep donated organs viable for years.
