Scientists have created egg-like cells capable of fertilization using DNA from ordinary skin cells in what could be a major breakthrough for infertility research.

Using a newly developed technique to remove excess chromosomes, a team led by clinical biologist Nuria Marti-Gutierrez of Oregon Health & Science University has created human eggs that can undergo successful fertilization and start to develop into zygotes.

A clinical application for this technique is still at least 10 to 15 years away, the authors speculate, and some key challenges and ethical obstacles remain, but it's a proof of concept that may offer hope for future cases of infertility.
