What this research studies

This project uses the microscopic worm C. elegans to learn how egg and sperm cells organize and separate chromosomes during meiosis. Scientists will examine the cellular structures, DNA breaks, and crossover events that help chromosomes pair and segregate, using genetic tools and high-resolution imaging. By watching these processes in the worms, the team aims to identify mechanisms that prevent too many or too few chromosomes (aneuploidy). Those findings could help explain why some human pregnancies end in miscarriage or result in chromosomal birth defects.

Who could benefit from this research

Good fit: There is no patient enrollment for this lab-based project, but the findings are most relevant to people affected by recurrent pregnancy loss or chromosomal birth defects.

Not a fit: Patients seeking immediate clinical treatments or trials are unlikely to benefit directly because this is basic research conducted in a non-human model.

Why it matters

Potential benefit: If successful, the work could reveal basic mechanisms behind chromosome errors that lead to miscarriage and birth defects and guide future diagnostic or preventive strategies.

How similar studies have performed: Previous studies using C. elegans and other model organisms have successfully uncovered conserved meiotic mechanisms, so this approach builds on an established track record.
