Scientists have produced kangaroo embryos through fertilization in the laboratory for the first time, in a development that they can help maintain endangered animals.
Australian researchers at Queensland University of East Gray Kangarian embryos using sperm injection into the mouth (ICSI), a technique that is widely used in human IVF, where sperm is injected into a mature egg.
Dr. Andres Gambini, who led the research, said technology can be used to maintain Genetic diversity In the risk of extinction, such as koala and demons tesmania and hairy tumors in the north.
He said that the team produced more than 20 fetuses using ICSI so far, as it collected sperm and eggs from the kangaroo that recently died in wildlife hospitals.
Gambini said that East Grace was a good type of artificial insemination experience due to the availability of extensive genetic materials: its population is high, with excessive abundance in some areas.
ICSI does not require abundant live sperm cell Artificial insemination – In some types, such as koala, Sperm does not work As well as after freezing. “We do not need millions of sperm alive, we only need a few of them,” Jambini said.
He added that there were no plans to produce direct Joyes from artificial insemination embryos, given the abundance of species. He said: “Our next step is to start an improvement in technology, and to understand more childbearing physiology … so that we can move towards applying the same technology to other pods.”
Genetics can be stored from animals that died from predation, disease, or car collision as a frozen embryos, and the team hopes, allowing the wealthy preservation opportunities to introduce genetic diversity into ecosystems.
“We need genetic fluctuations in the population to ensure that the population is to survive over time and be able to adapt to the environment,” Gambini said.
He said that industrial pollination will not be a silver bullet to protect endangered species from extinction, but “another tool in our memorization set”, along with strategies such as population monitoring, education and habitat protection.

Australia was described as “the world leader of Endowment of mammals“With 38 species lost since colonialism.
“For the first time, with Mars, what appeared to be a truly promising progress” in artificial insemination.
“We have worked very hard for 20 years, for nearly 30 years, to do the IVF in any Australian patch without real success,” said Rodger. Industrial pollination was attempted in the early first decade of the twentieth century in Tamar and Al -Labis.
Rodger said that there was no national facility for the genetic samples of biological medicine from Australian Mars. “In a very silly way because we have a national facility to maintain the diversity of the plant,” he said. “We have huge facilities for storing sperm and fetus for laboratory animals, especially mice.”
Rodger called for a “wide range of tissue” Maintaining genetic diversity To save.
The research was presented at an international conference of the Association of embryonic technology last month, with a summary published in the magazine Reproduction, fertility and development.
