A pores and skin pattern taken from a rhino might provide an opportunity at new life, due to groundbreaking work by a wildlife charity—almost 4 years after the animal’s passing.
The southern white rhino, aged 40 and beforehand housed at Whipsnade Zoo, died in October 2021. Following her loss of life, veterinarians collaborated with three specialist organizations to recuperate tissue samples from her physique.
Now, the Whitchurch-based charity Nature’s SAFE has efficiently grown “thousands and thousands” of residing cells from a kind of samples—an achievement it believes is a primary for the UK.
This marks a key step in an modern scientific course of that would ultimately permit researchers to develop sperm or egg cells from the classy tissue, enabling the rhino to contribute to the species’ gene pool lengthy after her loss of life.
The preserved pattern got here from the rhino’s ear and was cryogenically frozen at -196°C to keep up cell viability. The hope was that, when thawed sooner or later, these cells could possibly be revived and used to generate contemporary cell strains.
In April, the frozen cells had been fastidiously thawed and efficiently cultured, almost 4 years after the animal’s loss of life. Lab technician Lucy Morgan, who led the hassle, famous that these cells symbolize viable genetic materials that continues to be out there for conservation use, even within the absence of the animal.
Nature’s SAFE, sometimes called a “residing biobank,” at present holds organic samples from over 300 animal species—together with 37 which are critically endangered and 4 which are already extinct within the wild.
The charity’s mission is to fight extinction by preserving genetic variety and supporting reproductive applied sciences like IVF and synthetic insemination.
In line with Debbie Rolmanis, Chief Operations Officer at Nature’s SAFE, pores and skin cells are particularly worthwhile as a result of they’re simple to gather and could be cultured indefinitely. This makes them a renewable useful resource for preserving DNA in functioning cells.
Commenting on the breakthrough, Tullis Matson, the charity’s founder and chair, referred to as it a possible “game-changer” for conservation. He highlighted that verifying the viability of the rhino’s cells years after her loss of life is a big step ahead and will assist save different at-risk species, such because the mountain rooster frog or Lake Pátzcuaro salamander.
“This isn’t nearly one rhino,” he mentioned. “It’s a beacon of hope for numerous species teetering on the sting of extinction.”
