Within the field in the field of reproductive biology very few issues have generated so controversy and excitement like the potential and existence of the ovarian stem cells. Over the years the belief was that female mammals are born with a set quantity of Oocytes (immature eggs) which decrease with time, resulting in the loss of fertility. Recent research has raised doubts about this, by introducing the idea that ovarian stem cells, which are able to produce oocytes that can be produced throughout women’s lives. It is time to explore the fascinating subject.
What are the ovarian stem cells?
Stem cells are cells that have not been differentiated with the potential to transform into various types of special cells. Ovarian stem cells are also called oogonial stem cells (OSCs) are the only form of stem cell located within the Ovaries. Contrary to the majority of other cells within your body, these stem cells possess the capacity to divide and produce the oocytes which mature into eggs throughout a woman’s reproduction years ( Nature).
The Discovery of Ovarian Stem Cells
The possibility of the existence in ovarian stem cells inside mammals was first suggested during 2004 by an group comprised of researchers headed by Dr. Jonathan Tilly. They discovered that female mice were able to make new oocytes all through their lives, and challenge the assumption that female mammals were born with only a limited amount of eggs ( National Institutes of Health).
This finding was initially met with suspicion, but later research studies have confirmed Tilly’s research findings and revealed OSCs throughout mammals, which includes humans. In 2012, an enlightening research published in the journal Nature Medicine confirmed the presence of OSCs in human ovaries of adult age ( Nature Medicine).
The potential for Ovarian Stem Cells
The development of OSCs is opening many new avenues within the realm of reproductive medical research. If the cells are managed and harnessed it could revolutionize the treatment of infertility and aging-related decrease in the quality of eggs.
Researchers are looking for methods for stimulating an increase in the number of oocytes by OSCs for women who have diminished fertility or premature ovarian insufficiency. Also, there is the possibility to prevent menopausal symptoms through extending the lifespan of reproduction in the female ovaries. But, it’s vital to keep in mind that these treatments are in the midst of study and not currently available as treatment options ( Human Reproduction Update).
The Road Ahead
Although the research into the ovarian stem cells has opened up new avenues of exploration but there’s still a lot we aren’t aware of. More research is required in order to better understand how they function and how they are stimulated to create oocytes and the implications this could be for women’s health and fertility. This is a fascinating period in reproductive biology, as researchers continue to uncover the secrets of ovarian stem cell.
In the end The ovarian stem cell represents the beginning of a new paradigm regarding our knowledge of reproductive biology in women. The discovery of ovarian stem cells has not only been a challenge to long-held assumptions, but could open up new avenues in the field of reproductive medical research. We await with anticipation the outcomes of future and ongoing research on this intriguing area.
