These cells show a typical immunophenotypic profile, including CD29+, CD34+, CD44+, CD90+, CD105+, CD19−, CD45−, CD324−, and HLA-DR− (Figure 1) [3], with the secretion of several factors like TNF-α, IL-6, and VEGF that enhance inflammation, tumor growth, and metastasis by creating a feedback loop that promotes further cytokine release [2]. Here, IL6 is linked to neoplasm.
