A step towards understanding embryo implantation

About author

How would you explain your research outcomes to the non-scientific community?

In India, ICMR estimates that nearly 1:5 couples face difficulties in conceiving. In many such infertile couples, in vitro fertilization (IVF) is a treatment of choice for biological parenthood. However, the success rate of IVFs is very low, as many good quality embryos do not implant into the womb. This is a major hurdle because we do not understand how embryos implant into the uterus. The inner lining of the uterus is called the endometrial epithelium. It is the site where the embryo implants and establishes pregnancy. In this study, we aimed at investigating a key protein E-cadherin in the endometrial cells. E-Cadherin is responsible for cell-cell attachment in the epithelium. Using the mouse as a model, our results show that this protein molecule changes its location under the influence of ovarian steroid hormones (estrogen and progesterone) and thus regulates epithelial tissue architecture.

How do these findings contribute to your research area?

For the first time, we have been able to capture this phenomenon of EMT in mice endometrial epithelium specifically at the time of implantation. This opens our understanding of the epithelial barrier, which is not rigid but moves like a rolling gate under special conditions to aid the embryo to initiate pregnancy. These findings not only help solve fundamental questions about implantation but can also help modulate the endometrial tissue to improve the IVF rates in future.

What was the exciting moment during your research?

There were multiple exciting moments as we serendipitously stumbled upon E-cad dynamic organization. Earlier pointed out by Deepak while observing the slides under the microscope, I did not believe it until I developed the 3D surface plots of epithelial cell. We are very thankful to Bobby from TIFR for lending her technical expertise in confocal microscopy using, which we could capture the phenomenon in 3D cultures of human endometrial cells. This was the most crucial point, as we did not have expertise in our Institution for this experiment. With single-cell resolution, we knew we were in for a treat, as this was a new addition to the available literature.

What do you hope to do next?

How do you intend to help Indian science improve?

Our lab continuously focuses on promoting the research findings on the social media sites like Facebook, Twitter, etc, apart from the mainstream research portals. We make sure that we explain the crux in common man’s language. I aim to increase the inclusivity of the common people in research by opting for various methods, such as public interactions, write-ups etc. After all, we get to use taxpayers’ money for research. In addition, at the lab, we regularly discuss about various Indian scientists and women in science.Recently, there was an exciting initiative by Deepak on celebrating the nine days of Navratri by talking about nine Indian women in STEM. We have shared this information on several social media platforms and with family and friends.I also intend to return to India and conduct research after being trained at Montreal in some cutting-edge areas in neuroscience.
