Preventing age-associated egg aneuploidy

As women age, the frequency of egg aneuploidy increases. This phenomenon represents one of the biggest barriers in fertility treatment. In this study, we successfully suppressed aneuploidy in eggs from aged mice. By developing a protein-based artificial kinetochore to fine-tune the pulling forces exerted by microtubules on chromosomes, we prevented premature chromosome separation, a major cause of age-associated aneuploidy. These effects facilitated the production of euploid eggs. These findings open a new avenue for future applications in infertility treatment.
