Potential to Polarise
Factors governing egg production have been uncovered in zebrafish ovaries. Using a lab-grown long-term model system of egg (oocyte) development, the mTOR-Stat3-Stathmin molecular pathway is found to be key for oocyte polarisation (how a cell organises within and that is vital for developmental processes), establishing a state of 'polarisation competence' – the oocyte’s ability to develop the potential to polarise

What is BPoD?
BPoD stands for Biomedical Picture of the Day. Managed by the MRC Laboratory of Medical Sciences until Jul 2023, it is now run independently by a dedicated team of scientists and writers. The website aims to engage everyone, young and old, in the wonders of biology, and its influence on medicine. The ever-growing archive of more than 4000 research images documents over a decade of progress. Explore the collection and see what you discover. Images are kindly provided for inclusion on this website through the generosity of scientists across the globe.
BPoD is also available in Catalan at www.bpod.cat with translations by the University of Valencia.
