Abstract
Serendipity plays a huge role in science, and having a prepared mind that can seize upon a serendipitous observation or occurrence can drive a project forward. This happened in my lab with a project centered on the regulation of trophoblast cell behavior at implantation. We discovered that amino acids regulate the onset of trophoblast motility through the activation of the kinase complex mTORC1, and that this acts as a checkpoint to trophoblast differentiation. This finding not only broadened our understanding of the mechanisms underlying embryo implantation, but also provided new ways of thinking about the regulation of diapause, a state of suspended embryonic development that occurs in many species. I should say that we re-discovered the fact that amino acids regulate the onset of trophoblast motility, as reading the literature showed us that others had made this same observation some 30 years previously and we were fortuitously able to build upon those findings. This project confirmed to me how valuable it is to read the literature widely, both historical papers and those in fields outside one's area of research, and to go to seminars on topics outside one's area.
