GLI2 and neoplasm: Using the Human Protein Atlas [30,31,32], we evaluated Gli2 expression within normal subcutaneous adipose tissue [33,34] and found that Gli2 expression was limited to mesenchymal cell populations, such as fibroblasts and adipose progenitors, while absent in most immune cell populations (Figure S4), leading us to hypothesize that Hedgehog signaling may facilitate stromal interactions within the tumor microenvironment.
