COLOSSAL BIOSCIENCES

LABORATORY
DIVISIONS

There are many pieces to the de-extinction puzzle. Each its own discipline which requires intense study, hard-earned experience and unceasing commitment to protecting our planet and its inhabitants.

Genome Engineering

Thanks to our partnership with Dr. George Church, Colossal is at the forefront of the science of genome engineering, also referred to as genome editing. Our team has access to the most advanced tools and decades of Harvard-backed research to empower us to alter genetic code at new leves of safety and precision.

Embryology

Colossal is home to a world-renowned team of embryologists, working on groundbreaking research in the field of embryo culture and interspecies somatic cell nuclear transfer that will make cloning a viable option for critically-endangered species.

Computational Biology

Our computational team is working to build high-quality reference genomes for all endangered species for genomic preservation and establishing the baselines for population health assessment. Sequencing endangered species for the first time ever allows us to investigate areas of the genome that are under advanced selection or evolution and to characterize main drivers involved in ecological niche-driven phenotypes such as coat patterning and coloration, size, and novel herbivore or carnivore body structure.

Exogenous Development

Establishing in-vitro embryo culture, maturation and development is instrumental in the preservation and restoration of species at the brink of extinction. Our technology will help protect and reduce interference on endangered populations as an enormous amount of energy expenditure is required for gestation and is often unsuccessful due to fractured populations, late sexual maturity and extremely long gestation times.

Stem Cell
Reprogramming

The ability to reprogram any cell type and derive stem cells gives scientists and conservation biologists access to cell types, such as gametes, that otherwise would have been unretrievable in species at risk of extinction and are essential to re-establishing healthy populations.

Cellular Engineering

Colossal is developing the world’s most robust cell culturing system, taking in any available sample from endangered species and establishing cell lines with novel media formulations. These cell lines are characterized through karyotyping, cell-cycle analysis, and next-generation sequencing that produces in-depth analysis of endangered species lines.

Animal Husbandry

Our world-class team of dedicated animal care and husbandry experts focus everyday on providing optimal wellness for all animals in our care. In addition to accelerating the development of advanced reproductive technologies such as in-vitro fertilization and ovum pick up, our team is developing cutting-edge husbandry and care strategies for the species we are restoring from extinction.

What is Genome Engineering?

Genome Engineering sits at the core of de-extinction – remodeling the intact DNA of the closest living relative to that of the extinct species. This platform leverages cutting-edge genome editing modalities combined with DNA synthesis to make precise changes to the DNA in single bases or in bulk, in a multiplexable fashion. The essence of an organism is determined by its DNA, thus making key changes to genetic regions associated with desired traits, will restore a functional version of the organism that is best suited for restoring the health of our ecosystems.

Reprogramming

What is Stem Cell Reprogramming?

Stem Cell Engineering is the science of reversing time for cells. The field is fundamental for engineering cells into an earlier developmental stage, and then back to desired matured stages using chemicals and transcription factors. Generation of induced pluripotent stem cells (iPSCs) earned Shinya Yamanaka a Nobel Prize in Physiology and Medicine and has since revolutionized stem cell biology. Deriving non-model organism iPSCs is not only crucial for Colossal’s de-extinction work, but also fundamental for conservation as it can be used to study development and disease, drug screening, cell therapies, and very importantly, they are the gateway to deriving gametes in vitro.

Division Roles & Highlights

Dr. Evan Appleton is Head of Stem Cell Biology with strong expertise in
bringing together transcription factor library screening and evolution, and computational workflows of lineage determination and cell-type classification. He is tremendously passionate about non-model stem cell engineering across all species of interest at Colossal.

[ IMPORTANT QUESTIONS ABOUT THE SCIENtific research we are doing at colossal ]

Is it really possible to de-extinct dinosaur species?

In order to de-extinct any species you need well-preserved DNA. However, non-avian dinosaurs lived between about 245 and 66 million years ago, in a time known as the Mesozoic Era.

Studies show that DNA has a half-life of 521 years and even at an ideal preservation temperature of −5 ºC, DNA is fully unsequenceable after roughly 6.8 million years.

Therefore, from the perspective of DNA preservation, it’s not currently possible to bring back dinosaurs. Furthermore, Colossal is myopically focused on the restoration of the woolly mammoth, thylacine, and dodo to their native ecosystems in order to fulfill the ecological void left from their extinctions.

Is this going to be like Jurassic Park? Didn’t we already learn that lesson?

While our team is fond of the movies, Colossal’s work is rooted in disruptive conservation and motivated by a desire to create healthier ecosystems for all living creatures.

We’re working with the world’s top scientists and bioethicists to ensure our de-extinction work is executed safely and ethically. Thanks to our world-renowned scientific advisory board, we’re confident that we’re entering the conservation world at a pivotal moment and that our thoughtful disruptive conservation techniques will radically change how we combat climate change and the loss of biodiversity.

Does Colossal have plans to de-extinct other species?

Our team is intensively centered around the woolly mammoth, thylacine and dodo. However, our de-extinction priorities are to target keystone species, which play an invaluable role in maintaining the health of ecosystems. Therefore, our priority is to bring back species which will fill the ecological void that was created when they went extinct, while helping restore the degraded ecosystem.

In the Arctic, a crucial region for preventing climate change, we are thus prioritizing the woolly mammoth because it played a critical role in ecosystem functions which collapsed in the late Pleistocene era. Outside of the Arctic, we are focused on the thylacine for similar reasons. The dodo’s posthumous celebrity as the symbol of human driven extinction places a responsibility on us to return them to the habitat they once inhabited peacefully and its de-extinction will provide a platform to develop technologies that will enable bioengineering-based conservation of living avian species.

As we make progress on these projects, we’ll constantly evaluate other species for which de-extinction efforts can have a positive impact on the ecosystem and advance conservation science.

Our overarching vision is to preserve life in all its forms. We’re leveraging our technological developments while collaborating with on-the-ground species partners to establish holistic, modular toolkits which can be adapted to additional species as need be. We’re remaining thoughtful and intentional in the way we harness this work to positively impact all species: extinct, extant and ensuing.

What is the process and timeline for
the de-extinction of Colossal’s species?

Mammoth
The de-extinction of the woolly mammoth has been led by Colossal Co-Founder and Lead Geneticist, George Church, Ph.D. for the last two decades. The process requires 11 distinct steps, from DNA sequencing to gestation. In regards to timeline, elephants have one of the longest gestation periods of any animal at 22 months. Accounting for this, we aim to have our first calves within four to six years.

Thylacine
The de-extinction of the thylacine, which has been spearheaded by Andrew Pask of the University of Melbourne for the last two decades, requires 10 distinct steps.

The genomes of the thylacine and one of its closest living Dasyurid relatives need to be sequenced, after which marsupial cell lines must be established before beginning to gene edit the hundreds of thylacine loci into a host genome. Thereafter, we must generate the thylacine embryo, implant it into a surrogate dunnart mother for gestation (8-42 days), and transfer it to an external artificial pouch for maturation. As firm believers in radical transparency, we will publicly share all significant progress throughout this process.

Dodo
The de-extinction of the dodo, which is led by Colossal's Chief Science Officer, Beth Shapiro, Ph.D. along with collaborators Tom Gilbert and John Fjeldsá from the University of of Copenhagen, requires 7 intricate steps, starting with identifying and analyzing the dodo and host genomes to predict mutations affecting phenotypes and ending with producing living dodos through a surrogate system.

At this stage, executing the steps described in our high level de-extinction process, and predicting how mutations affect adaptation and speciation will be imperfect. We aim to assess our engineering efforts at the two year mark to better understand what additional efforts may be required, if any.

Is Colossal resurrecting, cloning
or genetically recreating species?

By definition, to “resurrect” is “to restore life; revive the practice, use or memory of (something); bring new vigor to.” To “recreate” is “to create again; reproduce; re-enact.” Colossal Labs are leveraging CRISPR-based genetic engineering and other technologies to reproduce close approximations (not clones) or extinct species’ genomes in order to restore the species to life.

Through de-extinction, we are thus genetically recreating genomes in order to resurrect species. For context, our Dictionary of De-Extinction provides background on the semantics of de-extinction.

Will Colossal’s de-extinct species be
genetically identical to the original ones?

The genomes of Colossal’s de-extinct species will be reconstructed by genetically engineering those of their closest living relatives. Therefore, while it is not currently possible to bring back an extinct species that is genetically, behaviorally, and psychologically identical in every way, they’ll have all core biological traits of recently extinct ancestors.

They will walk like them, look like them, sound like them, and most importantly, behave like them – fulfilling their original ecological roles within the native ecosystems impoverished by their disappearance.

What’s the likelihood of success?

Everything is in place to make de-extinction a reality. The technology for genome engineering already exists and our scientists are making significant progress on the assisted reproductive technologies necessary for each unique species as well as optimizing the editing techniques.

Exogenous
Development

What is Exogenous Development?

Exogenous development, or ex-utero development, refers to the growth and development of an organism outside of the uterus or womb. Ex-utero development technology can aid in de-extinction efforts by providing a way to gestate and develop embryos from extinct species.

De-extinction involves using genetic engineering techniques to recreate extinct species by inserting their DNA into the genomes of closely related living organisms. However, once the DNA has been altered, there needs to be a way to develop the resulting embryos and bring them to term. One approach to this problem is to use surrogate mothers from closely related species to carry the embryos to term. However, this approach may not always be feasible, particularly if the closely related species is endangered. Ex-utero development technology offers an alternative solution. By creating an artificial womb that mimics the conditions of the uterus, scientists can gestate and develop embryos from extinct species in a controlled environment.
