In a groundbreaking development, Colossal Biosciences, a $1.5 billion startup, has announced a significant milestone in its quest to bring the wooly mammoth back from extinction. With the creation of reprogrammable elephant cells, the company is one step closer to achieving their ambitious goal. This breakthrough could potentially revolutionize the field of de-extinction and help protect endangered species from the effects of climate change.
Colossal Biosciences’ “Momentous” Advance
Cofounder and CEO Ben Lamm described the company’s latest achievement as “momentous,” as it could open up several new avenues of research, including the creation of building blocks for a mammoth baby. The startup, valued at $1.5 billion, has set its sights on not only resurrecting the wooly mammoth but also the dodo, to bolster biodiversity and aid species on the brink of extinction.
The company’s long-term goal is to create a mammoth-like, gene-edited creature through in vitro fertilization (IVF) by 2028. This breakthrough in reprogramming elephant stem cells brings them closer to realizing this vision, while also potentially benefiting living elephants, which are notoriously difficult to study in laboratory settings.
The Significance of Stem Cells
Stem cells are naturally occurring in the body and possess the unique ability to develop into various cell types, such as bones, hair, skin, and organs when given the appropriate instructions. This process, known as differentiation, involves exposing the cells to a complex mixture of chemicals that guide them toward their final cell type.
Until recently, it was believed that the differentiation process was irreversible. However, in the early 2000s, scientists discovered a cocktail that could revert differentiated cells into stem cells, known as induced pluripotent stem cells (iPSCs). This breakthrough allowed biologists to reprogram iPSCs into previously inaccessible cell types for laboratory studies.
Overcoming the Elephant Stem Cell Hurdle
While the dedifferentiation cocktail proved effective for most species, including humans, monkeys, big cats, and birds, elephant stem cells remained stubbornly resistant to the process. Colossal Biosciences’ team of scientists, led by co-founder and Harvard geneticist George Church, worked tirelessly to tweak the chemical composition of the mixture until they finally cracked the code.
Church emphasized the significance of this achievement, stating, “Elephants might get the ‘hardest to reprogram’ prize, but learning how to do it anyway will help many other studies, especially on endangered species.” This breakthrough not only brings the company closer to creating a mammoth but also offers new opportunities to study and understand elephant biology.
The Potential for Mammoth Creation
With the ability to reprogram elephant stem cells, Colossal Biosciences can now explore the creation of various cell types essential for a mammoth, such as hair and cold-resistant fat storage, in the laboratory setting. Team lead Evan Appleton expressed excitement about using the developed cells to grow elephant gametes, the sperm and egg cells necessary for fertilization, in a dish.
The creation of gametes in the lab would eliminate the need to harvest them from elephants, making the process more ethical and efficient. Developmental biologist Vincent Lynch, who is not involved in Colossal’s work, believes that the goal is to turn these iPSCs into sperm and eggs, enabling in vitro fertilization and, eventually, surrogacy.
Understanding Elephant Gestation
In addition to its potential for de-extinction, the research conducted by Colossal Biosciences could also shed light on the complex and lengthy process of elephant gestation. Eriona Hysolli, the head of biological sciences and mammoth lead at Colossal, emphasized the importance of understanding the developmental biology aspect of elephant biology.
Hysolli noted that elephant gestation is incredibly long and complex, making it crucial to gain a deeper understanding of this process. By studying the reprogrammed elephant stem cells, scientists can gain valuable insights into the intricacies of elephant development, which could ultimately aid in the conservation of these majestic creatures.
The Road Ahead
While the creation of reprogrammable elephant stem cells is a significant milestone, Hysolli cautioned that the team is not yet ready to produce baby mammoths. The next hurdle will be to determine how to tweak these elephant stem cells to create cells from the extinct wooly mammoth species.
The process of unraveling the genetic differences between elephants and mammoths and figuring out how to incorporate those differences into the reprogrammed cells will require further research and experimentation. However, with the dedication and expertise of Colossal Biosciences’ team, they are well-positioned to tackle this challenge head-on.
The Potential Impact on Biodiversity
The resurrection of the wooly mammoth is not merely a scientific curiosity; it holds the potential to have a significant impact on biodiversity. By bringing back this iconic species, Colossal Biosciences aims to restore balance to ecosystems that have been disrupted by the loss of keystone species.
The reintroduction of the wooly mammoth could have far-reaching effects on the environment, from altering vegetation patterns to influencing the behavior and populations of other species. This, in turn, could help to mitigate the effects of climate change and ensure the survival of endangered species.
Ethical Considerations
As with any groundbreaking scientific endeavor, the de-extinction of the wooly mammoth raises ethical questions that must be carefully considered. Some argue that resources would be better spent on protecting existing endangered species rather than attempting to resurrect extinct ones.
Others worry about the potential ecological consequences of reintroducing a species that has been absent for thousands of years. Colossal Biosciences’ team is well aware of these concerns and is committed to addressing them through open dialogue with the scientific community and the public at large.
