Expanded vacuum-stable gels for multiplexed high-resolution spatial histopathology

Yunhao Bai, Bokai Zhu, John-Paul Oliveria, Bryan J. Cannon, Dorien Feyaerts, Marc Bosse, Kausalia Vijayaragavan, Noah F. Greenwald, Darci Phillips, Christian M. Schürch, Samuel M. Naik, Edward A. Ganio, Brice Gaudilliere, Scott J. Rodig, Michael B. Miller, Michael Angelo, Sean C. Bendall, Xavier Rovira-Clavé, Garry P. Nolan, Sizun Jiang. pmc.ncbi.nlm.nih.gov. July 7, 2023.

This proof-of-concept study introduces ExPRESSO for higher-resolution imaging of archived tissue on existing mass-spectrometry platforms. The reported lateral enlargement is about 3.7-fold, with axial compression, edge distortion and marker-specific signal limits. Alzheimer’s examples use six individuals, not hundreds of patients; vessel counts and image fields are nested observations. Nolan’s disclosed FDA funding and instrument-company interests are explicit. The study does not report UAP patients, a secret government approach or a clinical diagnostic trial.

Highly multiplexed spatial profiling with CODEX: bioinformatic analysis and application in human disease

Wilson Kuswanto, Garry Nolan, Guolan Lu. ebi.ac.uk. November 21, 2022.

This narrative review explains CODEX tissue imaging, processing limitations and spatial analysis. Its disease examples summarize cited studies; they do not supply a new patient cohort or independent replication. The review calls for stronger causal and prospective validation.

CellSeg: a robust, pre-trained nucleus segmentation and pixel quantification software for highly multiplexed fluorescence images

Michael Y. Lee, Jacob S. Bedia, Salil S. Bhate, Graham L. Barlow, Darci Phillips, Wendy J. Fantl, Garry P. Nolan, Christian M. Schürch. ebi.ac.uk. January 18, 2022.

CellSeg combines a pretrained nucleus-segmentation model with image scaling, stitching, mask expansion and pixel statistics. Historical benchmark scores and representative tissue examples have different provenance and settings; densely packed tissue remains difficult. A colorectal comparison reuses 140 samples from 35 people and provides author-described gating and correlation. Correlation does not establish exhaustive cell truth or universal clinical accuracy. Source-native metric definitions, count conflicts and caption errors are preserved.

Immune cell topography predicts response to PD-1 blockade in cutaneous T cell lymphoma

Darci Phillips, Magdalena Matusiak, Belén Rivero Gutierrez, Salil S Bhate, Graham L Barlow, Sizun Jiang, Janos Demeter, Kimberly S Smythe, Robert H Pierce, Steven P Fling, Nirasha Ramchurren, Martin A Cheever, Yury Goltsev, Robert B West, Michael S Khodadoust, Youn H Kim, Christian M Schürch, Garry P Nolan. ebi.ac.uk. November 18, 2021.

This observational tissue analysis links immune-cell topography to pembrolizumab response in14selected lymphoma patients from an earlier24-patient trial. Seventy regions and large cell counts remain nested within those patients. Assay validation and resampling reuse the same cohort, without an independent clinical test. Several abundance and signature measures were null; the proposed chemokine mechanism is not causally demonstrated. Nolan is a corresponding coauthor/joint supervisor. Published government grants and commercial/patent disclosures remain attributed, without establishing a classified approach or UAP programme.

Multimodal Analysis of Composition and Spatial Architecture in Human Squamous Cell Carcinoma

Andrew L Ji, Adam J Rubin, Kim Thrane, Sizun Jiang, David L Reynolds, Robin M Meyers, Margaret G Guo, Benson M George, Annelie Mollbrink, Joseph Bergenstråhle, Ludvig Larsson, Yunhao Bai, Bokai Zhu, Aparna Bhaduri, Jordan M Meyers, Xavier Rovira-Clavé, S Tyler Hollmig, Sumaira Z Aasi, Garry P Nolan, Joakim Lundeberg, Paul A Khavari. ebi.ac.uk. July 23, 2020.

The authors combine sequencing and imaging to describe selected squamous-cancer tissue, including a tumour-specific keratinocyte population. Cells, spots and fields depend on small patient subsets. Predicted interactions and proximity do not establish causal immune suppression. A linked correction repairs duplicated and mislabeled figure material; its unchanged-conclusions statement is attributed to the authors.
