Australian scientists for the first time in history created Kangaro embryos with the help of in vitro fertilization (IVF). According to researchers, this is a breakthrough achievement that one day can help save endangered species.
Scientists from the University of Queensland described their achievement in the magazine “Reproduction, Fertility and Development”.
– Australia is home to the largest number of marsupial species in the world, but also has the highest indicator of mammalian extinction – noted the author of the study Dr. Andres Gambini. – Our ultimate goal is to support the protection of endangered marsupials, such as coals, Tasmanian devils, rough -haired wombaty and dwarf lotils – he added.
According to the NON Profit Invasive Species Council, since the European settlement of Australia, this continent has lost at least 33 species of mammals.
The first Kangaro's embryo was created
In their project, scientists assessed the development of Kangarzych eggs and sperm conducted in laboratory conditions. Later, they formed embryos using a cytoplasm (ICSI) sperm microinaches – a technique of direct injection of a single sperm into a mature egg. – Because giant kangaroos (Macropus giganteus) They occur in excessive numbers, we took their eggs and sperm to use them as a model to adapt our embryonic technology already used in breeding animals and people – explained Dr. Gambini. – Access to marsupial tissues is a challenge because they are less studied than breeding animals (…). We are currently improving the techniques of collecting, breeding and storing eggs and sperm sperm. While working on protection methods, we strive to secure the genetic material of these unique and valuable animals for the future – added the specialist.
Andres Gambini believes that this technique can be used for other animals at risk of extinction. For now, however, scientists have not been able to bring the kangaroo to IVF. – Although it is difficult to provide the exact schedule, thanks to constant cooperation, financing and further technological progress we hope that the birth of a borneur by in vitro fertilization can become reality within a decade. Our success in Kangaroo embryos breeding is extremely satisfying, culminating in many years of study, research and cooperation – said Dr. Gambini.
