Researchers made a significant discovery in fertility science. They were able to develop human eggs using skin cells. This is cause for optimism for many people globally who are unable to have children. It could change our assumptions about human reproduction.
Researchers turned a regular skin cell into human eggs. This newly developed process is known as in vitro gametogenesis. This process utilizes the genetic material of the person. This could be a way for people who cannot produce eggs to conceive. This could be beneficial for same-sex couples, as well.
Researchers would first take a simple sample of a skin cell. They then take out the nucleus of this skin cell. The nucleus contains the majority of the genetic code. They create a donor egg first, in which they take out the donor egg’s genetic material, and insert the skin cell nucleus into the donor egg.
There could be embryos created without a biological mother, by implanting the egg. For women who are unable to carry a pregnancy, it could facilitate parenthood. It could create paths to parenthood for the infertile couple. It could eliminate particular forms of infertility completely.
Experts believe they will need a minimum of ten more years. To begin with, they will need to put it through rigorous testing. Only then, once demonstrated to be both safe and effective, will it proceed to testing on humans, after it has been tested on animals first.
This technology raises multiple ethical concerns. Society will need to have very serious conversations about the moral implications of such technology. There will also need to be some type of legal framework for this kind of procedures. There will also be a regulatory approval before researching clinical use.
This study is published in Nature Communications. This was a project led by Oregon Health & Science University. Darren Mitalipov was the director of the research team. This is an extension of what they previously worked on in cellular reprogramming.
