Figure 7. Clonal evolution of MSC subpopulations in patients with bone metastases from breast cancer. (A, B) Pseudo-time values (A) and developmental trajectories (B) of MSC subpopulations, pie charts representing the proportion of control and breast cancer bone metastasis patients in MSC subpopulations. (C) Co-expression modules of transcription factors in MSC subpopulations of patients with breast cancer bone metastases. Left: Identification of regulator modules based on the regulator’s linkage specificity index matrix. Middle: representative transcription factors and their binding patterns in the modules. Right panel: cellular subpopulations in which transcription factors are located. (D) Single-cell atlas showing transcription factors regulating MSC subpopulations.
