Research overview

In this study, we conducted transcriptomic analysis on cumulus cells cultured with varying exosome concentrations and identified 334 differentially expressed long noncoding RNAs (lncRNAs). Functional enrichment analysis indicated that the differentially expressed lncRNAs may be involved in cumulus cell expansion, oocyte maturation, and embryo development.

Key findings

The development and maturation of mammalian oocytes are crucial stages in reproduction, directly influencing embryo health and the genetic quality of offspring.

Follicular fluid serves as the microenvironment for oocyte development, with exosomes playing a key role in regulating the activities of cumulus cells and oocytes.

However, the mechanisms governing porcine oocyte maturation remain incompletely understood.

In this study, we conducted transcriptomic analysis on cumulus cells cultured with varying exosome concentrations and identified 334 differentially expressed long noncoding RNAs (lncRNAs).
