Galectin-3 was expressed on multiple cell types, depending on the zone: leukocytes in the proximal zone (Figure 5a,h), CSCs and fibroblasts in the border zone (Figure 5b,h), and non-proliferating tumor cells in the distal and remote (Figure 5c,d,h) regions, respectively. The gene discussed is LGALS3; the disease is neoplasm.
