GSE140182: Single cell RNA sequencing of advanced gastric cancer

Bulk RNA sequencing

To define the cellular characteristics of malignant ascites of advanced gastric cancer patients and search for therapeutic strategies, we applied single cell RNA sequencing to cancer cells and tumor associated macrophages (TAM), present in large numbers in malignant ascites. We analyzed 180 cells from 4 malignant ascites and 1 cerebrospinal fluid metastasis. The results indicate that the anti-inflammatory characteristics of the tumor associated macrophages are concocted by the tumor cells. By constructing reference transcriptomes for M1 and M2 type macrophages, we found a strong non-inflammatory property of macrophages recovered from the malignant ascites of gastric cancer.
