A group of scientists has created artificial human sperm and eggs using human embryonic stem cells and skin cells. While researchers have already previously accomplished this using rodents, this is the first time they were able to replicate the process with human cells.
Their final products were not actually working sperm and eggs, but rather germ cells that potentially could mature and become viable for fertility. The study's findings were published Wednesday in the journal Cell.
"Germ cells are 'immortal' in the sense that they provide an enduring link between all generations, carrying genetic information from one generation to the next," Azim Surani, PhD, professor of physiology and reproduction at the University of Cambridge, said in a press release. Read more
