Colossal Biosciences has entered a formal partnership with the U.S. Fish and Wildlife Service (USFWS) to create a comprehensive, cryopreserved genetic library of species protected under the Endangered Species Act. By collecting and sequencing tissue samples, the collaboration aims to provide a "digital twin" of biodiversity, offering future researchers the genetic data needed for conservation, resilience-building, and potential de-extinction efforts.
How the Genetic Biobank Operates
The initiative seeks to secure the genomes of the more than 2,100 species currently listed under the Endangered Species Act of 1973. According to Colossal Biosciences, the process involves collecting non-invasive biological samples, such as skin biopsies or blood, alongside tissues from deceased animals provided by zoos or wildlife recovery teams.
Once collected, these samples are stored in liquid nitrogen at approximately -274°F. Before freezing, the cells undergo full-genome sequencing to create a permanent digital record. Scientists also intend to derive induced pluripotent stem cells (iPSCs)—blank-slate cells capable of being engineered into various tissue types—from these samples. This work builds on previous breakthroughs, such as the successful derivation of iPSCs from elephants, as noted by Colossal’s Chief Animal Officer Matt James.
Why Genetic Preservation Is Necessary
The project addresses a rapid decline in global biodiversity. Data from the Center for Biological Diversity suggests that up to 30% of the planet’s genetic diversity could disappear by 2050 due to habitat loss, climate change, and pollution. While the U.S. has seen 54 species recover enough to be delisted since 1973, 67 species have gone extinct during that same period.
USFWS Director Brian Nesvik stated that the collaboration is designed to complement existing conservation tools. By understanding the genetic markers associated with disease resistance or drought tolerance, researchers hope to assist imperiled populations in adapting to a warming climate. This biobanking effort is intended to be open-source, providing universities and research institutions access to the genetic data to aid in long-term species recovery.
Comparison: Domestic and Global Biobanking Efforts
This partnership represents a significant expansion of existing efforts to catalog life.
| Feature | USFWS & Colossal Partnership | Dubai Museum of the Future Project |
|---|---|---|
| Primary Goal | Endangered Species Act recovery | Global species preservation |
| Target Scope | U.S. endangered/threatened species | Over 10,000 species |
| Key Focus | Genomic resilience and conservation | Public education and interactive science |
| Status | Active; ongoing collection | Launching October 2024 |
The Dubai initiative, announced by Colossal in February, utilizes a "hub and spoke" model to store indigenous tissue samples. Unlike the U.S. effort, which focuses heavily on domestic regulatory recovery, the Dubai facility incorporates an educational wing where visitors can observe laboratory work, aiming to bridge the gap between complex genetic science and public engagement.
Future Applications of Biobanking
The long-term utility of the frozen samples extends beyond simple storage. By identifying genes that provide environmental resilience, scientists may be able to guide breeding programs or, in extreme cases, use gene editing to help survivors withstand new pathogens or shifting ecosystems.
While Colossal is well-known for its de-extinction projects involving the woolly mammoth and the dodo, the company maintains that the primary goal of this USFWS partnership is to keep existing species from disappearing. The project represents a shift in conservation strategy, moving from reactive habitat management to proactive biological insurance.
