For the first time, biologists from the University of Cambridge in Great Britain and the University of California in the United States reported that human embryos were created from stem cells without the participation of sperm and eggs.
Publika.az reports that these cellular structures are at a very early stage of human development. Scientists hope to use this experiment to better understand the causes of miscarriage and genetic diseases.
Synthetic structures have no brain or heart. But they contain the cells needed to make the placenta and egg yolk.
Moreover, the study authors were able to achieve an unprecedented breakthrough by growing three layers of germs under conditions that recreate the womb.
Currently, the practice is suspended because laws prohibit the cultivation of human embryos older than 14 days.
Before creating human embryos, scientists have already tested their technology on mouse and monkey stem cells. They managed to grow living structures from them.
However, evidence from previous studies is mixed because synthetic monkey embryos implanted in women’s wombs did not develop into viable fetuses. The artificial mouse embryos were able to go further and develop a brain and a beating heart, but then they too died.
It is not clear whether there is a biological reason why these structures die at a certain point, or whether these problems are caused by technical obstacles that can be overcome.
Researchers hope to go further to study the nature of female infertility and human development.
