Summary
Our lab focuses on one of the biggest problems developed nations are facing in 21st century: Late-stage motherhood, and associated fertility problems. The decrease in fertility rates is leading to a population decline in majority of the developed nations from Japan to Spain, which will have unprecedented consequences for our societies in near future.
Poor oocyte quality accounts for the majority of female fertility problems, however, we know little about how oocytes can remain healthy for many years or why their health eventually declines with advanced age. World-wide data show that more than 25% of female fertility problems are unexplained, pointing to a huge gap in our understanding of female reproduction. Our lab strives to help fill this gap by studying immature oocytes.
We’re interested in three main lines of research:
1 - How do oocytes maintain proteostasis?
A remarkable feature of reproduction is that the offspring does not inherit the ageing status of their parents. In mammals, the embryo inherits the cytoplasm from the mother, in the form of the oocyte cytoplasm. This suggests the existence of mechanisms to counteract the accumulation of intracellular damage in the oocytes. We are studying these mechanisms to reveal how oocytes establish and maintain proteostasis.
2 - What is the metabolic state of mitochondria in oocytes?
Mitochondria in oocytes are the sole source of mitochondria for the new embryo, and thus, their quality is extremely important for proper development. We are working with human and frog (Xenopus leavis) oocytes to understand the metabolic nature of mitochondria in oocytes.
The majority of mitochondria in human and frog early oocytes lie in the Balbiani body, which can be thought of as a “superorganelle” that clusters other organelles. The Balbiani body is stable only in the dormant oocytes, and disperses upon oocyte activation. Our previous research has shown that the Balbiani body forms an amyloid-like cage around organelles that could be protective. We investigate the function of the Balbiani body, as well as features of mitochondria inside and outside of this superorganelle.
Balbiani bodies, labeled “BB” in these images of an immature frog egg (left) and immature human egg (right, larger scale), hold organelles together in one spot next to the nucleus, “n,” in the months or years before an egg matures. Images: Elvan Boke (left), Arthur Hertig (right)
3- Are primordial oocytes susceptible to aging?
Oocyte quality declines with increasing maternal age, but we do not know whether age-related defects are already present in primordial oocytes or are acquired during oocyte maturation. Indeed, it is unknown to which extent oocyte aging is caused by cell-intrinsic mechanisms or by the aging microenvironment (cell-extrinsic). Answers to these questions might allow us to develop therapeutic strategies that delay or even prevent oocyte decline with age.
We use oocytes from two vertebrate species, frogs and mice, which are complementary for their ease of handling and relationship to human physiology. We also collaborate with Hospital Clinic Barcelona and Clinica Eugin to obtain human immature oocytes.
