A breakthrough by researchers from Cambridge University, has revealed that in just two years same-sex couples could have their own biological children by using stem cells of parents of the same sex.
The researchers have proven that human egg and sperm cells can be made from stem cells in the skin of two adults. They have stated that the technique could mean same-sex couples could have babies in just two years.
The scientists used stem cell lines from embryos as well as cells from the skin of five different adults. Ten different donor sources have been used so far and new germ-cell lines have been created from all of them.
The team, funded by The Wellcome Trust, compared the engineered stem cells with human cells from foetuses to make sure they had identical characteristics.
Azim Surani, leader of the project, told The Sunday Times:
We have succeeded in the first and most important step of this process, which is to show we can make these very early human stem cells in a dish. We have also discovered that one of the things that happens in these germ cells is that epigenetic mutations, the cell mistakes that occur with age, are wiped out.”
