When everything seems to be going against you, remember that the airplane takes off against the wind, not with it.
~ Henry Ford (July 30, 1863 - April 07, 1947)
Evolutionarily, germ cells are one of the most ancient cell types, needed by every type of animal to reproduce. Their developmental program is very similar, whether we are talking fruit flies or humans. As a result, these findings could eventually help us understand and treat defects in germ cell development that lead to human infertility and disease.
~ Mark van Doren (June 13, 1894 - December 10, 1972)
