Japanese scientists managed to get offspring from two male mice, but it will not be possible to completely get rid of the participation of females in this process: the female will be needed, even if only “male” genetic material is used to create the embryo. give birth to offspring. This was told socialbites.ca by a professor, one of the leading researchers at the Institute of General Genetics. NI Vavilov RAS, Professor of the Department of Genomics and Bioinformatics and Head of the Scientific and Educational Center for Genomics Research of the Siberian Federal University Konstantin Krutovsky.
“Researchers have shown how in mice germ cells can be obtained from ordinary cells, particularly skin cells. If these germ cells are transferred to the seminal glands, spermatozoa develop from them, and if they are transferred to the ovaries, eggs develop. Or, if they are transferred to the ovaries, they will develop eggs. Or they can take an artificially obtained egg and replace it with a normal sperm from the same person or another person. so that the same male can be both “mother” and “dad”, or two different males can be “mother” the other “dad” and vice versa.In humans, this not only solves the problem of infertility, but also produces offspring from a single male or male partners But without the woman – a surrogate, no one can do it, ”she explained.
Earlier Japanese scientists reported They announced at a conference in London that they were able to produce healthy offspring from two male mice. The researchers created stem cells from male mouse skin cells, removed the Y chromosome and duplicated the X chromosome, and then transformed the stem cell into an egg. As a result of 600 implantation attempts, seven cubs were born, which later acquired their own offspring.
