Platform for Quantitative Detection of Endometrial Immune Cells Based on Immunohistochemistry and Digital Image...

Area of Science:

• Reproductive immunology
• Immunohistochemistry
• Digital pathology

Background:

• Recurrent miscarriage (RM) involves complex endometrial immune dysregulation.
• Accurate quantification of endometrial immune cells is crucial for understanding RM pathogenesis.
• Conventional methods for immune cell analysis in endometrium are limited.

Purpose of the Study:

• To develop and validate a digital immunohistochemistry image analysis platform.
• To quantitatively assess endometrial immune cells in patients with recurrent miscarriage.
• To characterize the endometrial immune microenvironment in reproductive failure.

Main Methods:

• Endometrial tissues from RM patients were collected during the mid-luteal phase.
• Immunohistochemistry (IHC) was performed for specific immune cell markers (CD56+ uNK cells, Foxp3+ Tregs, CD163+ M2 macrophages, CD1a+ DCs, CD8+ T cells).
• A digital slide scanner and commercial image analysis system were used for quantitative analysis.

Main Results:

• The developed platform enabled accurate and efficient quantification of endometrial immune cells.
• The system facilitated analysis of immune cell percentages within the total endometrial cell population.
• This methodology allows for detailed characterization of the endometrial microenvironment and immune cell interactions.

Conclusions:

• The digital image analysis platform provides a robust method for evaluating the endometrial immune microenvironment.
• Quantitative assessment of endometrial immune cells is clinically significant for diagnosing and treating recurrent miscarriage.
• This technology can be applied to study immune cell heterogeneity in various reproductive failure conditions.
