Leveraging Optimized Transcriptomic and Personalized Stem Cell Technologies to Better Understand Syncytialization...

Area of Science:

• Reproductive biology
• Developmental biology
• Genomics

Background:

• Human placentation is crucial for understanding and treating pregnancy complications.
• Stem cell-derived models have advanced the study of trophoblast (TB) development.
• Previous transcriptomic methods had limitations in analyzing the syncytiotrophoblast (STB).

Purpose of the Study:

• To review advancements in studying human placentation using stem cell models and transcriptomics.
• To highlight the utility of single nuclei RNA sequencing (snRNA-seq) for STB transcriptome analysis.
• To discuss patient- and disease-specific in vitro models for pregnancy disorders.

Main Methods:

• Application of RNA sequencing (RNA-seq) technologies to trophoblast (TB) models.
• Utilizing single nuclei RNA sequencing (snRNA-seq) to overcome limitations in STB transcriptome analysis.
• Development of novel stem-cell derived in vitro models for studying placental development.

Main Results:

• snRNA-seq has enabled a more comprehensive understanding of the syncytiotrophoblast (STB) transcriptome.
• New stem cell models facilitate patient- and disease-specific studies of pregnancy disorders.
• Combined approaches allow for detailed investigation of STB developmental abnormalities in preeclampsia (PE).

Conclusions:

• Advancements in stem cell technology and snRNA-seq provide robust tools for studying human placentation.
• These methods offer unprecedented opportunities to investigate the developmental basis of pregnancy complications like preeclampsia.
• Future research can leverage these tools for personalized medicine approaches to pregnancy disorders.
