Australian scientists have achieved a milestone by creating the world's first kangaroo embryo through in vitro fertilisation (IVF), a development that could have implications for preserving endangered species. By injecting a single sperm cell into an egg from eastern grey kangaroos, the researchers have opened new possibilities. However, they note that further advancements are needed to achieve a live birth.
Lead researcher Andres Gambini highlights that this breakthrough not only offers valuable insights into marsupial reproduction but also holds promise for enhancing genetic diversity among at-risk species like the koala, Tasmanian devil, northern hairy-nosed wombat, and Leadbeater's possum.
Australia is home to a diverse range of marsupials, but also faces significant challenges with mammal extinctions. The University of Queensland study involved cultivating kangaroo eggs and sperm in a lab environment, culminating in the creation of embryos using a technique called intracytoplasmic sperm injection (ICSI).
By focusing on eastern grey kangaroos, a non-endangered species with healthy populations, the researchers aim to refine methods for preserving the genetic material of iconic Australian marsupials. Dr. Gambini emphasizes the importance of these advancements in safeguarding the genetic legacy of these unique animals.
This innovative use of IVF mirrors global efforts to conserve endangered species, including a previous milestone in 2018 when the world's first donkey embryo was successfully created using similar techniques.
