Cervical function in pregnancy and disease: new insights from single-cell analysis

Area of Science:

• Reproductive biology and pathology
• Single-cell transcriptomics
• Cervical pathophysiology

Background:

• The uterine cervix is crucial for fertility, pregnancy maintenance, parturition, and reproductive tract protection.
• Cervical dysfunction leads to adverse clinical outcomes like infertility, preterm birth, and cervical cancer.
• Understanding cervical molecular events is vital for effective treatment strategies.

Purpose of the Study:

• To review insights from single-cell transcriptomic studies in human and mouse cervical tissue.
• To highlight the potential of single-cell technologies in identifying biomarkers and therapies for cervical diseases.
• To address outstanding questions in cervical biology and pathophysiology.

Main Methods:

• Review of single-cell transcriptomic studies in human and mouse cervical tissue.
• Analysis of cellular heterogeneity and molecular pathways in the cervix.
• Comparison of cervical tissue with other reproductive tract regions.

Main Results:

• Single-cell analysis reveals dynamic plasticity of cervical epithelial cells during the reproductive cycle.
• Distinct immunological responses in the cervix compared to upper reproductive tract regions were identified.
• Single-cell technologies uncovered cellular heterogeneity and potential cancer stem cells in cervical tumors.

Conclusions:

• Single-cell transcriptomics provides crucial insights into cervical biology in health and disease.
• These findings accelerate the development of biomarkers for disease prediction and prevention therapies.
• Further application of single-cell technologies will enhance understanding of preterm birth and cervical cancer progression.
