Figure Lengend Snippet: a , UMAP plots showing the different non-malignant and malignant cell states identified for each major cell type in the STS scRNA-seq reference atlas, including endothelial cells, cancer associated fibroblasts (CAFs), B cells, lymphoid, and myeloid cells. b , Scatter plots showing the correlation between the abundance of cell types recovered in bulk RNA-seq of post-treatment formalin-fixed paraffin embedded (FFPE) samples using CIBERSORTx and measured through flow cytometry in the matched dissociated fresh tumor samples. Spearman’s correlation coefficients and two-sided P-values are displayed on the graph. The line of best fit by linear regression and 95% confidence intervals are shown on the graph.
Article Snippet: RNA was extracted from FFPE pre-treatment core needle biopsies and surgically resected tumors using RNAstorm FFPE RNA Extraction Kits (Cell Data Sciences).
Techniques: RNA Sequencing, Formalin-fixed Paraffin-Embedded, Flow Cytometry
