Comparing mouse decidualization models reveals artificial decidualization (AD) closely mirrors natural pregnancy decidualization (NPD) at the transcriptomic level. The in vitro decidualization (IVD) model requires optimization for better accuracy in studying decidualization.
Area of Science:
- Reproductive Biology
- Developmental Biology
- Genomics
Background:
- Decidualization is crucial for pregnancy success.
- Mouse models are vital for studying decidualization.
- Existing models (NPD, AD, IVD) lack comprehensive molecular comparison.
Purpose of the Study:
- To comparatively analyze transcriptomic differences and similarities between mouse decidualization models.
- To assess the reliability of artificial decidualization (AD) and in vitro decidualization (IVD) against natural pregnancy decidualization (NPD).
Main Methods:
- RNA sequencing (RNA-seq) was employed for comparative transcriptomic analysis.
- Differential gene expression analysis was performed across NPD, AD, and IVD models.
- Gene expression consistency and inconsistency were quantified between models.
Main Results:
- Artificial decidualization (AD) showed high consistency with natural pregnancy decidualization (NPD), with 1977 consistently expressed genes.
- In vitro decidualization (IVD) exhibited lower consistency with NPD, featuring 310 consistently and 456 inconsistently expressed genes.
- Key decidualization markers showed divergent expression in the IVD model, with Prl8a2 up-regulated and Alpl down-regulated.
Conclusions:
- Artificial decidualization (AD) is a reliable transcriptomic model for studying mouse decidualization.
- The in vitro decidualization (IVD) model requires significant optimization to accurately reflect natural pregnancy decidualization at the transcriptomic level.
- This comparative analysis enhances understanding of mouse decidualization models for future research.
