This article caught my attention because today in biology 30 we were discussing the accepted knowledge that oocytes or eggs cells (the female gametes involved in sexual reproduction) are non-renewable - that women are born with all of the eggs that they will ever have. According to the article however, a study performed on the stem cells found in adult women has revealed that the reproductive pool of female gametes may be renewable (outside of the body), alike to male sperm cells (in the body). The process of isolating the stem cells involves the identification of a protein called DDX4, unique to these cells. The majority of testing thus far has been performed on mice due to the legal and moral implications involved with research on human eggs, but scientists are hopeful and perceive this discovery as a landmark should their success continue. The potential this holds for advancements in the field of infertility treatment is groundbreaking, and could impact the lives of women undergoing in vitro fertilization and other means of conquering infertility, everywhere.
