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

Eur J Immunol. 2026 Feb;56(2):e70157. doi: 10.1002/eji.70157.

Abstract

We developed a 50-plex imaging protocol using the MACSima platform to characterize the microarchitecture of germinal centers in secondary lymphoid tissues. This workflow combines tissue processing, automated cyclic imaging, image preprocessing, and a new analysis method that detects morphological changes in irregularly shaped stromal cells.

Keywords: B cells; MACSima imaging cyclic staining; T follicular helper cells; follicular dendritic cells; germinal centers.
