Living Legacy: Reviving a Southern White Rhino Through Revolutionary Cell Preservation
Nature’s SAFE has regenerated living cells from a rhino that died in 2021, marking a pioneering conservation breakthrough that may help rescue endangered species through advanced bio-banking technology.
A remarkable conservation milestone has been achieved in the UK. A 40-year-old southern white rhino, once a resident of Whipsnade Zoo, passed away in October 2021. However, her genetic story did not end there. Vets, in collaboration with three special groups, collected tissue samples from her boat, setting the stage for a groundbreaking achievement.
Fast forward to 2025, nature's SAFE, pioneering Shropshire-based charity, has managed to generate “millions” of living cells from the preserved sample. This marks what is believed to be the first successful case in the UK of reviving viable cells from a deceased rhino. The charity, headquartered in Whitchurch, views this as a pivotal step in a futuristic process that could enable the creation of egg or sperm cells, potentially reintegrating the deceased rhino into breeding efforts. A critical detail in this achievement lies in the initial preservation method. A living skin sample was collected from the rhino’s ear and stored at an ultracold temperature of -196°C. This method aimed to retain the cells’ viability over time. In April, those very samples were thawed and, for the first time, successfully cultured into fresh cell lines nearly four years post-mortem.
Lab technician Lucy Morgan, who led this intricate cellular revival, remarked, “These cells represent living DNA from this rhino that is readily available for conservation use even though the rhino itself is deceased.”
Nature’s SAFE, often described as a “bio bank”, has now accumulated biological materials from 300 species, including 37 that are critically endangered and four that are extinct in the wild. Their mission is both scientific and visionary: to preserve biodiversity, rejuvenate technologies like artificial insemination and in-vitro fertilisation.
Debbie Rolmanis, the charity’s Chief Operations Officer, emphasised the enduring value of their work: “By preserving and cultivating skin cells from threatened species, we are building a living library of genetic material that can be used to help restore genetic diversity... and prevent extinction.”
Founder and Chair Tullis Matson called the achievement “an absolute game-changer,” highlighting how these technologies could save imperiled creatures like the mountain chicken frog or Lake Patzcuaro salamander from disappearing forever.
With each success, Nature’s SAFE strengthens a new paradigm of conservation—one rooted in cellular longevity, cryopreservation, and regenerative science. This isn’t just a story of one rhino—it’s a clarion call for the survival of species worldwide.
