A Texas genetics company working to bring back the woolly mammoth says it\u2019s a step closer to reviving another famed extinct species: the dodo.<\/p>\n

Dallas-based Colossal Biosciences Inc.<\/a> said Wednesday it developed a method to culture primordial germ cells of a close relative of the large, flightless dodo that disappeared in the 1660s.<\/p>\n

\u201cThis progress highlights how\u00a0Colossal\u2019s investment in de-extinction technology is driving discovery and developing tools for both our de-extinction and conservation efforts,\u201d\u00a0CEO and co-founder Ben Lamm said in a statement.<\/p>\n

Native to Mauritius in the Indian Ocean, the dodo has become a symbol of human-caused extinction. Scientists know relatively little about the bird, which stood roughly 3 feet tall and weighed up to 50 pounds.<\/p>\n

The startup also said it added more than $120 million to its latest funding round, bringing it to $320 million. Since its 2021 launch, the company has raised more than $555 million and says it’s now valued at $10.2 billion.<\/p>\n

Colossal garnered national attention in April when it said it had successfully rebirthed the dire wolf, a canine species that previously roamed North America and had been extinct for over 12,500 years. <\/p>\n

\u201cThis is our first true de-extinction, and it is the first time, you know, the world\u2019s ever had an extinct animal back on the planet. \u2026 It\u2019s pretty great,\u201d\u00a0Lamm said in an interview at the time. \u201cAs a Texas company, it\u2019s insane that we were able to do this, and the team did it within 18 months. This is a good testament to the technologies that are coming. We took a 13,000-year-old to a 73,000-year-old skull and made puppies. It\u2019s pretty magical.\u201d<\/p>\n

Some independent researchers have disputed the specifics of that claim. According to\u00a0the BBC<\/a>, several experts say the three \u201cdire wolf pups\u201d are genetically modified gray wolves, while also noting the births represent meaningful technical progress.<\/p>\n

Reviving an avian species differs significantly from reviving mammals, in part because of the size and opacity of bird eggs. It is not currently possible to clone birds. By editing primordial germ cells, the precursors to future egg and sperm cells, Colossal says it is one step closer to reviving avian species like the dodo. Before Wednesday’s announcement, such work had been achieved only in chickens and geese.<\/p>\n

\u201cThe first cell culture recipe was for chicken PGCs, and was published nearly 20 years ago,\u201d said Anna Keyte, Colossal\u2019s avian species director. \u201cUnfortunately, that recipe has not worked on any other bird species tested, even closely related species like quail. Colossal\u2019s discovery of a recipe for pigeons dramatically expands avian reproductive technologies and is the foundation for our dodo work.\u201d<\/p>\n

Lamm founded Colossal alongside Harvard University geneticist George Church with two main goals in mind: reversing extinction and preserving endangered species.<\/p>\n

Beyond the dire wolf and dodo, it has been working to de-extinct several well-known species including the Tasmanian tiger, another flightless bird called the Moa and the woolly mammoth.<\/p>\n

In March, Colossal announced it had genetically engineered mice that possess key \u201cmammoth-like\u201d traits adapted for cold environments.<\/p>\n

The company has said it expects to produce a woolly mammoth calf by the end of 2028.<\/p>\n

As for its dodo bird project, the company is using the Nicobar pigeon, the closest relative of the dodo bird living today, as the donor genome. The company established a colony of breeding pigeons in Texas that are laying eggs from the modified embryos. The company also is gene-editing chickens so they won\u2019t make their own germ cells.<\/p>\n

Colossal plans to inject the edited pigeon primordial germ cells into these \u201cdeveloping chicks, so that they carry pigeon germ cells rather than chicken germ cells,\u201d with the hopes that the chickens eventually lay eggs that hatch into pigeons and then someday the dodo itself.<\/p>\n

Beyond its ramifications of de-extinction, the company says this is an equally important step toward conservation and preserving modern-day endangered species.<\/p>\n

\u201cThis breakthrough in culturing pigeon primordial germ cells represents a transformative tool for avian conservation,\u201d said Beth\u00a0Shapiro, Colossal\u2019s chief science officer. \u201cBy developing these protocols, we\u2019re establishing crucial biobanking capabilities and opening new possibilities for genetic rescue of endangered species.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"A Texas genetics company working to bring back the woolly mammoth says it\u2019s a step closer to reviving…\n","protected":false},"author":2,"featured_media":166808,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[50],"tags":[100500,55602,100502,100501,99408,100499,200,100497,79,1022,100498,100496],"class_list":["post-166807","post","type-post","status-publish","format-standard","has-post-thumbnail","category-genetics","tag-avian-species","tag-colossal-biosciences","tag-de-extinction","tag-dodo","tag-extinct-species","tag-frederick-william-frohawk","tag-genetics","tag-primordial-germ-cells","tag-science","tag-texas","tag-texas-company","tag-woolly-mammoth"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/166807","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/comments?post=166807"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/166807\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media\/166808"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media?parent=166807"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/categories?post=166807"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/tags?post=166807"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
