• This method can be adapted for various target proteins in oocytes.

Purpose of Study

• To evaluate meiotic spindle assembly and organization in mouse oocytes.
• To investigate mechanisms regulating chromosome segregation.
• To assess potential disruptions leading to aneuploidy.

Methods Used

• siRNA-mediated depletion of specific mRNAs.
• Immunofluorescence analysis of oocytes.
• Collection of oocytes from female mice after hormonal treatment.
• Isolation of cumulus-oocyte complexes (COCs) using standard techniques.

Main Results

• Efficient transcript knockdown was achieved.
• Specific immunofluorescence analysis provided insights into spindle organization.
• The method demonstrated adaptability for studying various proteins.
• Findings contribute to understanding reproductive biology and aneuploidy mechanisms.

Conclusions
