It’s the first-ever kangaroo embryos that were achieved through Australian scientists, an innovation which utilizes IVF (in vitro fertilization). As told by The Guardian, such advancement marks the furtherance toward endangered marsupial species preservation.
It is through ICSI, a common technique applied in human IVF, that scientists at the University of Queensland achieved this. In this method, a mature egg is injected directly with a single sperm cell. The researchers produced more than 20 kangaroo embryos. They opened a window of opportunity in the conservation of Australia’s wildlife.
Major Step in Marsupial Conservation
Dr. Andres Gambini, the lead researcher from the University of Queensland, highlighted the importance of this scientific feat in protecting endangered marsupials.
“Australia is home to the greatest diversity of marsupial fauna on the planet but it also has the highest mammal extinction rate. Our ultimate goal is to support preserving endangered marsupial species like koalas, Tasmanian devils, northern hairy-nosed wombats and Leadbeater’s possums,” Dr. Gambini stated.
The researchers collected sperm and egg cells from eastern grey kangaroos that had recently died at wildlife hospitals. The species was chosen because of the abundant population; thus, they were ideal for trialling the new IVF technique.
How IVF Technology Can Aid Conservation Efforts
In conservation breeding programs, intracytoplasmic sperm injection (ICSI) is highly advantageous because it uses only a small number of live sperm cells. This means it is highly suitable for species like koalas, in whose sperm viability after freezing diminishes.
“We don’t need millions of sperm alive, we just need a few of them,” Dr. Gambini explained in emphasizing the efficiency of ICSI in reproductive research.
Although there are no plans to advance the kangaroo embryos to term at this time, the technology is being refined to help better understand marsupial reproductive biology, and it should eventually be available for use on other critically endangered marsupials.
“Our next step is to start getting better at the technology, understanding more of the reproductive physiology … so we can move towards applying the same technology to other marsupials,” he added.
The research team hopes to utilize IVF not only to breed endangered species but also to store genetic material from dead animals to ensure genetic diversity in ecosystems.
“We need genetic variability in a population to guarantee that population to survive over time and to be able to adapt to the environment,” said Dr. Gambini.
This milestone achievement offers a scientific lifeline for the endangered marsupials of Australia and opens up new avenues in wildlife conservation. IVF might soon become the ultimate tool that saves species on the brink of extinction as the research continues.
