Imaging Mass Cytometry (IMC) data for TNBC Samples

Imaging mass cytometry (IMC) data was collected on multiple regions of interest (ROIs) from a racially balanced and clinically matched cohort of 57 surgically resected tissues, primarily TNBC, as identified by H&E images. This cohort consisted of 26 self-reported Black American (BA) women and 31 self-reported White American (WA) women. ROIs were selected from both the tumor center and tumor periphery, and were categorized as either immune-rich or immune-poor.成像质谱流式细胞术（IMC）数据采集自57例手术切除组织的多个感兴趣区域（ROIs），该批组织以经苏木精-伊红（H&E）染色图像确认的三阴性乳腺癌（TNBC）样本为主。该队列种族均衡且临床匹配，包含26名自我报告为非裔美国（BA）女性与31名自我报告为白人美国（WA）女性。研究人员从肿瘤中心及肿瘤外周选取ROIs，并将其划分为免疫富集型与免疫贫乏型两类。
