title: Mapping spatial organization in ovarian cancer uncovers drivers of immune evasion

description: This collection of processed data accompanies the study: Yeh, Aguirre, Laveroni et al. Mapping spatial organization in ovarian cancer uncovers drivers of immune evasion. (2023). Unpublished. This collection of processed data is purposed for easy access and computing directly in the R programming environment. All files are provided in the form of RObjects (extension .rds). 


Data collected and processed for the first time as a part of this study include: de-identified clinical annotations for a cohort of 60 patients diagnosed with tubo-ovarian high grade serous carcinoma (HGSC), morphology annotations from clinical images (Hematoxylin and Eosin), targeted genomic data, single cell spatial transcriptomics on 95 HGSC tumors, CRISPR-screen data in ovarian cancer cells in co-culture with T and Natural Killer (NK) cells, and Perturb-Seq data in ovarian cancer cells co-cultured with NK cells.


Processed data from published journal articles include scRNA-Seq data downloaded from Synapse (syn33521743), Gene Expression Omnnibus (GSE118828, GSE173682, GSE147082, GSE154600, GSE146026).
