NES and neoplasm: Among them, for example, are proteasome proteins (thus enhancing the potential of MSCs’ immunological function), CD44 (associated with migration and intercellular interactions, playing an important role in microenvironment organization), POSTN (important for cell adhesion, enhancing the expression of VEGF family growth factors and involved in tumor cell sustenance [8]), differentiation-associated proteins (NES), the annexins ANXA1 and ANXA2, and others (Table S6, Supplementary Materials).
