T cells develop...
T cells develop from circulating precursor cells, which enter the thymus and migrate through specialised sub-compartments that support their maturation and selection. In humans, this process starts in early fetal development and is highly active until thymic involution in adolescence. To map the micro-anatomical underpinnings of this process in pre- and early postnatal stages, we established a novel quantitative morphological framework for the thymus, the Cortico-Medullary Axis, and used it to perform a spatially resolved analysis. By applying this framework to a curated multimodal single-cell atlas, spatial transcriptomics, and high-resolution multiplex imaging data, we demonstrate establishment of the lobular cytokine network, canonical thymocyte trajectories and thymic epithelial cell distributions within the first trimester of fetal development. We pinpoint tissue niches of thymic epithelial cell progenitors and distinct subtypes associated with Hassall's corpuscles and uncover divergence in the timing of medullary entry between CD4 vs. CD8 T cell lineages. These findings provide a basis for a detailed understanding of T lymphocyte development and are complemented with a holistic toolkit for cross-platform imaging data analysis, annotation, and Organ Axis construction (TissueTag), which can be applied to any tissue.
40-plex iterative bleaching...
40-plex iterative bleaching extends multiplexity (IBEX) imaging was performed on fixed frozen tissues from normal human lymph nodes and follicular lymphoma lymph nodes. Multiplexed immunofluorescence (MxIF) imaging was performed on serial FFPE tissue sections from follicular lymphoma lymph nodes. Four distinct antibody panels were applied to each tissue section referred to as MxIF Panel 1 (MxIF_P1), MxIF Panel 2 (MxIF_P2), MxIF Panel 3 (MxIF_P3), and MxIF Panel 4 (MxIF_P4). Multiplexed imaging was performed on serial FFPE tissue sections from normal and follicular lymphoma lymph nodes using the Cell DIVE imager and IBEX dye inactivation protocol (Cell DIVE-IBEX). Two panels of antibodies, immune (CellDIVE_IBEX_Immune) or stromal (CellDIVE_IBEX_Stromal), were applied to serial sections. IBEX and MxIF imaging were performed on a discovery cohort of 10 samples. Key spatial findings were extended to a larger validation cohort of 29 samples using the Cell DIVE-IBEX method.
