简介：
Overview
This protocol outlines standardized methods to isolate and process follicular fluid, somatic cells, and immature oocytes from IVF procedures, enabling high-quality molecular and cellular analyses. These approaches support translational research into fertility, reproductive aging, and ovarian dysfunction using materials typically discarded in clinical care.
Key Study Components
Area of Science
- Reproductive Biology
- Cell Biology
- Fertility Research
Background
- IVF byproducts are often discarded but can provide valuable insights into human fertility.
- Maintaining RNA integrity and cell viability is crucial for accurate analyses.
- Standardized methods are needed for effective sample processing.
- Research aims to uncover mechanisms of reproductive aging and fertility decline.
Purpose of Study
- To develop reproducible methods for collecting and analyzing IVF byproducts.
- To study human fertility, infertility, and reproductive aging.
- To identify ovarian cell types with age-related gene expression changes.
Methods Used
- Isolation of follicular fluid and somatic cells through centrifugation.
- Use of cryogenic storage for cell viability.
- Immunocytochemistry to confirm cell identity and viability.
- Quantification of specific cell markers (AMHR2, FOXL2) for analysis.
Main Results
- High-quality RNA and viable granulosa cells were obtained.
- Approximately 90% of cells stained positive for AMHR2.
- About 80% of cells stained positive for FOXL2, confirming granulosa cell identity.
- Insights into molecular underpinnings of human reproductive function were revealed.
Conclusions
- The protocol enables detailed study of reproductive aging and fertility decline.
- Future research will integrate multiomics and longitudinal studies.
- Dynamic follicular changes across age, environment, and disease states will be mapped.
