Experimental evidence that changes in oocyte growth influence meiotic chromosome segregation

Abstract

Our findings support the hypothesis that congression failure results from disturbances in the complex interplay of signals regulating folliculogenesis and that these changes subtly alter the late stages of oocyte growth, increasing the risk of a non-disjunction error. These findings have important implications for human aneuploidy, since they suggest that it may be possible to develop prophylactic treatments for reducing the risk of age-related aneuploidy.
