Transcriptomics of cumulus cells – a window into oocyte maturation in humans

Journal of Ovarian Research, 2020
Background Cumulus cells (CC) encapsulate growing oocytes and support their growth and development. Transcriptomic signatures of CC have the potential to serve as valuable non-invasive biomarkers for oocyte competency and potential.
