By focusing on a subset of MF tumor samples (MF17, MF18, MF21, MF24) for which we recently determined the transcriptional profile of the dominant malignant clones (clonotype 1) by scRNA-Seq (16), we predicted that these interactions occur with ITGB1 on malignant T lymphocytes (Figure 8B and Supplemental Table 6, E–H). Here, ITGB1 is linked to neoplasm.
