Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:The main limitation of our study is the small number of samples; however, this is inherent to studying rare entities such as collapsing glomerulopathy. For comparison even Nephroseq, a large database with >2,100 patient datasets, only has expression data from 6 patients with collapsing glomerulopathy, the same number as in our study (www.nephroseq.org, accessed July 2021, University of Michigan, Ann Arbor, MI). Furthermore, the ability to correlate a single glomerulus’ histology to its expression profile is not technically possible with laser capture microdissection which is the most common method used in the Nephroseq dataset. Another shortcoming is the small number of genes available in the Cancer Transcriptome Atlas probeset that was available at the time we performed this study (1,825 cancer and immunology-focused genes). Since then, a Whole Transcriptome Atlas probeset encompassing ∼18,000 protein coding genes has been released which will enable whole transcriptome analyses of disease processes in kidney biopsies. Other limitations of our study include validation failures if glomeruli were not preserved on deeper levels used for RNA-ISH or immunohistochemistry and difficulty in establishing causality and timing of mechanisms, which is common in all human biopsy-based studies. However, even with these limitations, we uncovered remarkable heterogeneity in glomerular expression patterns by disease and histology using DSP. Importantly, we found that there was good correlatio...
