    Spatial Transcriptomics Inc platform geomx digital spatial profiler
    A PULSE-CHASE iSILK paradigm. Experimental Design 1: PULSE period ( 15 N diet) between 6-10 months of age. Experimental Design 2: PULSE period between 6-10 months of age, CHASE period ( 14 N diet) between 10–18 months of age. Resulting Aβ1-42 MALDI MS isotopologue pattern that is right-shifted (Δm) due to increasing 15 N incorporation. B Representative images of plaque load from <t>GeoMx</t> whole slide scans, repeated on four independent whole-brain slices at 18-months and three at 10-months. C MALDI MSI single ion image of Aβ1-42 in cortex section. D Schematic overview of the correlative hyperspectral imaging and MALDI MSI experiment. 15 N enrichment (nitrogen index) was calculated as the AUC ratio of the 4th to 3rd peak in the Aβ1-42 isotopologue pattern. Higher values indicate greater 15 N incorporation. E Schematic overview of the correlative <t>spatial</t> <t>transcriptomics</t> (GeoMx) and MALDI MSI experiment. Stable 15 N enrichments (nitrogen index) corresponding to plaque age was calculated by extracting the FWHM of the Aβ1-42 peak, where a broader peak indicates increased 15 N incorporation and higher age. F Schematic overview of the validation experiment. Plaque morphology was evaluated by LCO hyperspectral imaging. IHC of selected proteins were correlated with plaque age, as evaluated by hyperspectral imaging. G Representative spectra from MALDI MSI showing the 14 N and 15 N-enriched Aβ1-42 m/z peak. H Aβ1-42 mass analysis comparing the plaque center (Cen) vs. the periphery (Peri) in 10-month-old mice ( p = 0.00017), ( I ) in 18-month-old mice ( p = 0.00000077), and ( J ) differences between cortex and hippocampus ( p = 0.022). H , I Linear Mixed Model accounting for across animals and repeated measures, point color indicates animal, 15 replicates over n = 3 m mice and 22 replicates over n = 4 m mice, respectively. J Two-sided Paired t-test, 22 replicates over n = 4 m mice, data presented as mean ± SEM. K Representative MALDI MSI image of 15 N and 14 N enriched Aβ1-42 distribution in plaques in 18-month-old mice. Parts of the figure created in BioRender. Szadziewska, A. ( https://BioRender.com/4qpojxz ) Image in ( E ) provided by Bruker Spatial Biology. Significance levels: *** P < 0.001, ** P < 0.01; * P < 0.05. Source data are provided as a Source Data file.

Consensus independent component analysis (c-ICA) was applied to each dataset to disentangle the bulk transcriptomic profiles into statistically independent transcriptional components (TCs). The TCs were then classified as CNA-TCs if they captured the effect of copy number alterations (CNA) based on the transcriptional adaptation to CNA profiling (TACNA).

Each column corresponds to a CNA-TC, with genes arranged in genomic order. For each CNA-TC, regions where many genes have high gene weights—indicating a CNA effect as determined by TACNA—are marked in red (see inset example).

Each column corresponds to a CNA-TC, with genes arranged in genomic order. For each CNA-TC, regions where many genes have high gene weights—indicating a CNA effect as determined by TACNA—are marked in red (see inset example). Only the red-marked regions, which represent the specific CNA effect captured by the corresponding CNA-TC, are shown. The CNA-TCs are sorted based on the position of the CNA region they capture.

    A Three examples of immune-TC activity across cell types are shown. Single-cell RNA sequencing included 114,253 cells from 181 patients with 13 different cancer types from the single-cell tumor immune atlas for precision oncology. The transcriptomic profile of each cell was projected onto the GPL570 immune-TCs. Cell annotation was based on the labels defined in the immune atlas. Box plot colors represent major cell type groups. The boxplot displays the median as the central line, with box hinges representing the second and third quartiles, whiskers extending by half the interquartile range, and outliers shown as individual dots. B Three examples of tumor spatial transcriptomic datasets from 10x Genomics Visium are shown. The transcriptomic profile of each spatial spot was projected onto the GPL570 CNA- and immune-TCs, and CNA burden was inferred. The spatial organization of the activity of three immune-TCs is shown for each tumor.
