Stem Cells Can Be Used to Cure Infertility
Researchers keep on finding new ways to develop a promising cure for infertility. This time researchers from the University of California, Los Angeles, focused on the growth of early germ cells in the fetuses of humans.
The team traced the same between 6 to 20 weeks, thereby examining when genes tended to switch on and when off. Since, the tiny ball of cells in the womb of a mother contains pluripotent stem cells and these can be formed into any form of body cells.
Also, the stem cells can be used to develop cure for infertility as well. But, before the same it is necessary to be known what happens in the human gametes' early developmental stages, the team affirms.
It now says that germ cells' DNA contains 'epigenetic modifications' and these structural changes affecting the way of genes' expression might be accumulating during the parents' lives. It might be that these need to be removed at the fetal stage.
"If we have no road map to follow, then we are just guessing. Now we have a snapshot of what these cells should look like, we can start mimicking them", co-author Amander Clark said.
