'Breeding' with artificial sperm
Japanese biologists have created mouse sperm in the laboratory by metabolizing their stem cells. From this cell, they gave birth to a very healthy group of mice.
>>>New findings bring hope to infertility
>>> Race sperm
First from stem cells, people have created the original sexual cells ( gonocyte ), then transplanted this cell into infertile mice. These mice become a body - an incubator ( organism-incubator ) where the mature cells become sperm. Using sperm to fertilize egg cells into embryos, and implant embryos into female mice.
Can "artificial sperm" improve the race in the future?
Through such a series of actions, very healthy baby mice were born, growing up into a population, both male and female, continuing to produce the following generations with physical indicators. and perfect health.
According to experts, the success of Japanese scientists has helped us to better understand the causes of problems (problems) in the process of conception and allow finding ways to cure infertility in many people. .
Researchers at Kyoto University, who published their work in the Cell Journal, emphasized: "Our studies are the first step towards the mechanism of spore-forming processes (gametogenesis - ie sperm and egg formation process in vitro Since then, we can find ways to cure infertility in many people '.
There are people through this success who have thought of a 'fiction': Can it be applied to improve the health and stature of future generations of a nation, and if so, What does it violate bioethics?
