Organ Mapping Antibody Panels: a community resource for standardized multiplexed tissue imaging

Ellen M Quardokus et al. Nat Methods. 2023 Aug.

Abstract

Multiplexed antibody-based imaging enables the detailed characterization of molecular and cellular organization in tissues. Advances in the field now allow high-parameter data collection (>60 targets); however, considerable expertise and capital are needed to construct the antibody panels employed by these methods. Organ mapping antibody panels are community-validated resources that save time and money, increase reproducibility, accelerate discovery and support the construction of a Human Reference Atlas.

Figures

Fig. 1
Fig. 1. OMAPs enhance standardization, discovery and stewardship of resources used in the spatial mapping of tissues at single-cell resolution.
a, Bar graph depicting the number of AS, CT and BP covered by each OMAP. Numbers were calculated by comparing with the relevant ASCT+B table and were reviewed by domain experts. b, Plot showing the cost to develop (filled circles) and use (unfilled circle) the OMAPs described here. Costs (in 2022 US dollars) are shown for antibodies and/or conjugation kits and exclude labor, amortization of purchased equipment such as microscopes, and consumables other than antibodies and conjugation kits. Cost to use is calculated for 100 tests. DNA (CODEX), Fluorophore (IBEX), Fluorophore* (Cell DIVE), Metal (SIMS). c, Schematic detailing the creation of a base OMAP panel. Gray antibodies indicate antibodies that do not pass the first quality control check for accurate immunolabeling. Colored antibodies outside of the filter reflect validated antibodies that are not suitable for the final OMAP, for example, need amplification or a different conjugate. d, Images of human lymph node depicting AS, CT and cell states identified using IBEX. GC, Tfr (follicular regulatory T cells), Treg (regulatory T cells), TBM (tingible body macrophages) and R1–R4 refer to different regions in the secondary follicle. 3++ indicates CD69++, ICOS++ and PD-1++; 1+ indicates CD69+ or ICOS+ or PD-1+. Large insets, 150 µm; small insets, 50 µm. Representative of a dataset of ten samples.

a, Main milestones in constructing an OMAP, outlined via steps 1–5. Nephron and renal corpuscle illustrations were adapted from the HuBMAP CCF 2D Reference Object Library. b, Metadata table illustrates the common fields shared across HuBMAP entities (OMAP, AVR and ASCT+B) to enhance search capabilities and promote community adoption of controlled vocabularies. Visit the Human Reference Atlas Portal (https://humanatlas.io/) for more details. c, In the future, OMAPs will be linked directly to the AVR searchable database, such that users can easily query information about BProtein markers for a specific OMAP. The ARWG is also collaborating with the Vitessce software team to create a user interface with grouped image channels by BProtein and CT that additionally displays annotations by subject matter experts.
