This submission contains single-cell RNA sequencing data generated from PBMC/buffy coat fractions from 29 donors: 12 patients with high-grade serous ovarian carcinoma, 4 non-malignant gynecological controls, 10 patients with breast cancer, and 3 healthy donor controls. The dataset was used to detect and characterize candidate naked CTCs and pcCTCs and to compare their transcriptomic profiles with platelet and cancer-related signatures.2026/07/14GSE337705GSM9859760GSM9859762GSM9859761GSM9859764GSM9859753GSM9859752GSM9859763GSM9859755GSM9859766GSM9859765GSM9859754GSM9859757GSM9859767GSM9859756GSM9859759GSM985975834281337705Homo sapiens
