The Barcelona CryoZoo represents a pioneering frontier in the conservation of global biodiversity through advanced biobanking and stem cell research technologies. This unique project, established under the auspices of the Barcelona Zoo Foundation and conducted in collaboration with the University Pompeu Fabra (UPF), the European Molecular Biology Laboratory (EMBL) Barcelona, and the Natural Science Museum of Barcelona, embodies a scientific commitment to preserving endangered species at a cellular level. By cryopreserving biological materials from a diverse range of animal species, especially those facing imminent extinction, CryoZoo offers an unprecedented molecular window into the complexity of life and the urgent need for conservation strategies driven by cutting-edge biotechnology.
At its core, CryoZoo functions as an extensive biobank specializing in animal cell lines, meticulously collecting, cataloguing, and preserving over 2,000 samples deriving from nearly 300 species including mammals, reptiles, amphibians, and fish. It transcends traditional cryopreservation by incorporating comprehensive molecular characterizations such as whole-genome sequencing, transcriptome profiling, and chromosomal mapping. These techniques generate rich datasets that not only safeguard genetic material but also provide invaluable insights into gene expression patterns and genomic architecture. This molecular repository is accessible to the global scientific community through approval by CryoZoo’s ethical and scientific review board, boosting international collaborative research efforts aimed at understanding and preserving biodiversity.
One of CryoZoo’s most groundbreaking initiatives focuses on the generation of induced pluripotent stem cells (iPSCs) derived from wild animal species. iPSCs, which are reprogrammed somatic cells capable of differentiating into any cell type, are pivotal for studying biodiversity at a functional genomic level without the ethical and practical challenges associated with live animal experimentation. Historically, the derivation of iPSCs has been predominantly successful in species genetically proximate to humans, primarily certain primates. The CryoZoo project now aims to expand this frontier by utilizing machine learning and artificial intelligence to decode and tailor the gene regulatory networks that govern cell reprogramming across a wider phylogenetic spectrum.

This AI-driven approach allows researchers to analyze gene activity patterns integral to cellular identity and plasticity, thereby formulating customized gene cocktails necessary for inducing pluripotency in diverse species. This technical advancement holds the promise of unlocking regenerative and reproductive capabilities in species ranging from dolphins to giraffes, whose genetic rewiring requirements for reprogramming are not currently understood. The fresh funding awarded by Revive & Restore, a leading nonprofit organization promoting biotechnology integration within conservation, facilitates this transformative research. Notably, among fifty global submissions, only three projects received this prestigious support, underscoring CryoZoo’s exceptional innovation and impact.
CryoZoo’s strategic collaboration with Spanish zoos, all members of the Iberian Association of Zoos and Aquariums (AIZA), along with specimens provided by the Natural Science Museum of Barcelona, enriches its biological sample diversity. This network ensures ethical sourcing of tissues and broadens the genetic representation within its biobank, crucial for generating comparative genomic data critical to evolutionary biology, species-specific disease mechanisms, and conservation-induced phenotypic plasticity. The integration of these diverse biological resources with advanced omics and computational biology harnesses a new paradigm of conservation research—where technology and ecology intersect to address species decline.
Recognizing the severity of the extinction crisis—currently threatening over 47,000 species globally as reported by the International Union for Conservation of Nature (IUCN)—CryoZoo’s work transcends mere preservation. It shapes a proactive scientific framework that anticipates conservation needs by enabling detailed biological characterization and practical regenerative solutions in the future. This vision aligns with the global conservation community’s shift towards genetic rescue and innovative conservation interventions that include disease resistance engineering, adaptive capacity enhancement, and potential synthetic biology applications.
Moreover, CryoZoo stands among the few global leaders influencing the IUCN’s Animal Biobanking Working Group, placing it alongside established institutions like the San Diego Zoo. Its contributions extend beyond sample storage to shaping policies and practices related to genetic resource use, ethical biobanking, and the deployment of stem cell technologies in wildlife.
The technical prowess of CryoZoo is embodied in its repository of over 350 cryopreserved cell lines, including seven successfully reprogrammed iPSC lines, 37 karyotypes reflecting chromosomal compositions across species, and genome sequences from 163 animal species. This foundational infrastructure enables the research community to conduct intricate genetic studies, investigate cellular mechanisms underlying species-specific traits, and explore novel pathways to mitigate species decline.
Integral to CryoZoo’s scientific leadership is the strategic use of transcriptomics, allowing the identification of active gene networks during the cellular conversion process. This molecular insight is key to understanding the epigenetic and gene regulatory landscapes that must be manipulated for successful iPSC generation, highlighting how each species’ unique evolutionary context shapes cellular reprogramming capacity. By decoding these complex molecular signatures, CryoZoo not only advances stem cell biology in wildlife but also develops frameworks potentially applicable to human regenerative medicine and comparative genomics.
The project also exemplifies the growing role of interdisciplinary approaches in wildlife conservation, merging molecular biology, bioinformatics, veterinary science, and ethical governance. CryoZoo operates within the Barcelona Biomedical Research Park (PRBB), leveraging state-of-the-art facilities and expertise. It also integrates within UPF’s Planetary Wellbeing initiative and EMBL’s Planetary Biology Transversal Theme—both emphasizing the sustainable interaction between human activity and biodiversity through scientific innovation.
Revive & Restore’s competitive grant, awarded in December 2024, marks a pivotal moment for CryoZoo, significantly bolstering its capacity to scale molecular phenotyping and stem cell reprogramming across taxonomically diverse species. This collaboration will likely catalyze the development of new conservation biotechnologies, stimulating broader adoption of cellular reprogramming techniques for wildlife disease research, recrudescence of endangered species, and long-term ecosystem resilience strategies in the face of climate change and habitat disruption.
In summary, the Barcelona CryoZoo is not just preserving cells: it is preserving the blueprint of life itself to empower a future where endangered species can be studied deeply, conserved effectively, and potentially restored through molecular and cellular sciences. Its integration of cryopreservation, genomics, stem cell technology, and computational biology positions it at the vanguard of conservation science, epitomizing how multidisciplinary innovation can address one of humanity’s greatest challenges—biodiversity loss.
