SMN1 and cancer: Similarly, within the stromal CD45neg and Desneg cell populations, the majority of Lamp1PMpos cells included cancer-associated fibroblasts (SMA) (cell cluster 7–9) and epithelial cells (cell clusters 10–11 in limb and 10 in trunk), but also expressed markers typical of myofibroblasts/mesenchymal cells, e.g., Ki67, Sca1, Sma, Pcam1, CD44, Lyve1, and EpCam (epithelial) (Fig. 5e–h).
