Spatial Profiling of Germinal Centers in Mouse Secondary Lymphoid Organs Using MACSima Imaging Cyclic Staining...

Area of Science:

• Immunology
• Cell Biology
• Biotechnology

Background:

• Germinal centers are crucial microenvironments within secondary lymphoid organs.
• Understanding germinal center microarchitecture is key to deciphering immune responses.
• Current methods may lack the resolution or multiplexing capability to fully characterize these complex structures.

Purpose of the Study:

• To develop and validate a high-plex imaging protocol for detailed germinal center microarchitecture analysis.
• To introduce a novel computational approach for analyzing stromal cell morphology within these tissues.

Main Methods:

• Development of a 50-plex imaging protocol on the MACSima platform.
• Integration of automated cyclic immunofluorescence imaging.
• Implementation of automated image preprocessing and a new stromal cell analysis algorithm.

Main Results:

• Successful characterization of germinal center microarchitecture using 50 markers.
• Detection of morphological alterations in irregularly shaped stromal cells.
• Establishment of a comprehensive workflow from tissue to analysis.

Conclusions:

• The developed 50-plex imaging protocol provides an advanced tool for germinal center research.
• The new analysis method enables detailed study of stromal cell dynamics.
• This workflow enhances the understanding of tissue structure in secondary lymphoid organs.
