New genetically modified animals experiment could be the key to the conservation of endangered species - Scientists have produced genetically modified animals that could serve as "surrogate parents," according to the BBC.
Thus, researchers have launched a high technology of genetic modification with the aim of eliminating a male fertility gene in animal embryos.
In this sense, the animals were born sterile. However, they began to produce sperm after an injection of sperm-producing cells from donor animals-which provide blood, an organ, bone marrow cells, or other biological tissue for transfusion or transplantation.
Genetic modification involves erasing or changing the coding in embryos. An example of the current technology is CRISPR, a biological system for altering DNA discovered in 2012 that scans the genome for the location of a certain gene and then uses "molecular scissors" to cut DNA.
However, if too much DNA is cut, other important genes may be altered.
The new technique would allow surrogate males to breed offspring carrying the genetic material of valuable elite animals.
In addition, it would be a step towards the genetic improvement of livestock to improve food production.

This can have a huge impact on the treatment of food insecurity worldwide. If we can approach this genetically, then it means less water, less food and less antibiotics that we have to put in animals, " explained Professor Jon Oatley of the College of Veterinary Medicine at Washington State University in the United States.
The experiment confirmed that the surrogate parents had active donor sperm, as the mice fathered a healthy offspring carrying the sperm donor genes.
Although the larger animals have not yet been reproduced, Professor Bruce Whitelaw of the Roslin Institute at the University of Edinburgh said the study provided a powerful proof of concept.
"This shows the world that this technology is real. It can be used, " he said.
"Now we have to go and figure out how to use it productively to help feed our growing population," he added.
According to the BBC, the technology could also help the conservation of endangered species.
In this regard, it may be possible, for example, to use the frozen sperm of an endangered rhino to regenerate the species.
However, according to scientists, the speed at which science could be launched will depend on the political authorities.
Approval for the human consumption of genetically modified livestock has not yet been granted, as there are concerns about Product Safety, Ethics and animal welfare.
However, genetic modification could be part of the response to many of the challenges facing societies in different parts of the world, including ensuring access to healthy and nutritious food, according to director Hugh Whittall.

Klarna becomes Europe's largest fintech unicorn after raising more than 500 million euros in its last round
Swedish fintech Klarna continues to rise like the foam: it has raised 546 million euros in the latest round of financing, led by Silver Lake and in which also participated the sovereign wealth fund of Singapore (GIC), BlackRock Inc. and HMI Capital, among others.
In this way, Klarna's valuation rises to 8.950 million euros, double that a year ago, according to Bloomberg, which makes it the largest fintech unicorn in Europe as described by CNBC.
The company's Chief Executive Sebastian Siemiatkowski has described this latest round of financing as "a great opportunity to expand the offer to consumers" in statements collected by Bloomberg. Now the idea is to expand across Europe, especially in France, a country with an important market.
Given the expected expansion and success in this latest round of financing, Klarna does not rule out launching a public offer to sell (OPV).
"With the number of partners we have, that's probably the natural evolution," explains the company's chief executive, Sebastian Siemiatkowski, in statements collected by Bloomberg.
Founded in 2005, the company has become very popular in the United States thanks to its installment payment service and, since July, is now available in Spain.
"The great advantage we have at Klarna is that we have 85 million users globally, "which allows them to know" very well the end consumer, " said the head of the company in Spain, Daniel Espejo, in an interview with Business Insider Spain in June.
