Not An Achievement, But A Warning.<\/strong> Spearheading this initiative is the distinguished molecular biologist, \u00a0Tom\u00e0s Marqu\u00e8s-Bonet\u00a0, who is recognized as one of the leading experts in genomics<\/a>. Marqu\u00e8s-Bonet emphasizes that this project is not merely a feat but serves as a last resort should the predominant species on our planet face extinction. He articulates the gravity of the situation by stating:<\/p>\n <\/p>\n Recovering species with these techniques is the failure of society, but it is astounding to be able to do it. The first priority must be to preserve animals in their natural habitats. When all else fails, it is better to have these banks than to be without them, like an ace up your sleeve.<\/p><\/blockquote>\n The concept underpinning Cryozoo is both \u00a0elegant and powerful\u00a0. Inspired by the renowned San Diego Frozen Zoo, the Cryozoo team collaborates with around twenty European zoos and aquariums to harvest small tissue samples, often during routine veterinary examinations. With just a millimeter of tissue, they can create a stock of \u00a0cell lines\u00a0, ensuring their long-term preservation.<\/p>\n <\/p>\n The process is surprisingly pragmatic. Zoos provide biopsies in specialized tubes containing a preservation medium. Unlike what one might expect, a complex cold chain is not always necessary; sometimes, as in the case of a stranded whale in Valencia, a simple serum suffices to kickstart the process.<\/p>\n <\/p>\n Conservation is Key.<\/strong> Upon arrival at the laboratory, technicians cultivate the cells<\/a>, allowing them to multiply and form a \u00a0homogeneous population\u00a0 known as a ‘cell line.’<\/p>\n The most revolutionary aspect of the Cryozoo’s work is their ability to \u00a0reprogram\u00a0 cells. By utilizing laboratory techniques, they can revert a skin cell to a pluripotent state, producing induced pluripotent stem cells (IPSCs). Marqu\u00e8s-Bonet elaborates, “A stem cell is a pluripotent cell, which means it can become whatever you need it to be.”<\/p>\n Once this step is achieved, the procedure culminates with the cryopreservation of both cell lines and IPSCs. Stored in liquid nitrogen, these cells can remain viable for decades, waiting for future scientific advancements to utilize them. This method mirrors that used for human embryo preservation<\/a>, commonly employed in fertility processes.<\/p>\n <\/p>\n Currently, Cryozoo houses over \u00a02,000 samples\u00a0 from nearly \u00a0300 species\u00a0, resulting in \u00a0350 high-quality cell lines\u00a0. Among its remarkable collection are cells from the \u00a0Montseny Triton\u00a0, Europe’s most threatened amphibian, the \u00a0Pyrenean frog\u00a0, and the \u00a0ORYX DAMMAH\u00a0, a species now extinct in the wild<\/a>. Notably, it also includes cells from ‘Pedro,’ a renowned rhinoceros that passed in 2023.<\/p>\n Quality Over Quantity.<\/strong> What sets Cryozoo apart is not its size but its relentless commitment to \u00a0quality\u00a0. The aim does not lie in accumulating cell lines but in producing the most viable ones. To this end, they have instituted a crucial and distinctive step: sequencing the complete genome of each generated cell line.<\/p>\n <\/p>\n This ensures that the genome of the cultivated cell accurately reflects that of the original animal, free from laboratory-induced genetic aberrations. Moreover, genome sequencing represents a significant leap for science, often marking the first instance of this technique applied to specific species. Such data will be stored in a repository accessible to researchers worldwide.<\/p>\n A Cautious Path Forward.<\/strong> Despite the ability to convert skin cells into reproductive cells, researchers have defined boundaries. They are not aiming for ‘de-extinction,’ instead viewing themselves as custodians of genetic material. The use of their cells for reproductive projects would require validation from the \u00a0International Union for Nature Conservation (IUCN)\u00a0 and a global consensus.<\/p>\n Ethics over Cloning.<\/strong> While it might be appealing to consider cloning animals, the reality is that it remains an expensive and inefficient process. According to Cryozoo, the real focus should be on preserving \u00a0ecosystems\u00a0, allowing animals to thrive naturally without human intervention.<\/p>\n <\/p>\n A Cell Bank for All.<\/strong> While resuscitating species may represent a distant possibility, the immediate applications of Cryozoo are revolutionary for contemporary research. Researchers can study diseases without inflicting harm on any living creature; they can infect cells with pathogens to observe reactions.<\/p>\n Additionally, they can fabricate \u00a0‘mini-organs’\u00a0 for studying species biology, safely test drugs, and investigate human diseases by examining the genetics of these animals.<\/p>\n With the looming challenges posed by climate change, the need for genetic preservation is crucial. As we brace for what could be an inevitable environmental crisis, initiatives like Cryozoo exemplify our proactive approach to \u00a0securing biodiversity\u00a0. Although the aspiration is that such genetic archives are consulted out of scientific curiosity rather than necessity, they represent earnest hope in an uncertain future.<\/p>\n Imagery Credits: Gary Bendig<\/a>, Julia Koblitz<\/a>.<\/p>\nTurning Biopsies Into Immortal Cell Lines<\/h2>\n
