In addition, the number of GFP+5TGM1 tumor cells in the BM of the femora and tibiae from the non‐injected, contralateral legs was significantly lower in the 5TGM1‐Samsn1‐inoculated mice compared to the 5TGM1‐EV‐inoculated mice (p = 0.0140, Mann–Whitney U test; Figure 2B). Here, SAMSN1 is linked to neoplasm.
