1) Vascular endothelial growth factor (VEGF), insulin growth factor 1 (IGF-1), single bulb chemical inducer protein 1 (MCP1), basic fibroblast proliferation factor (bFGF), IL6
2) Stem cell proliferation and differentiation: stem cell factor (SCF), leukemia blocking factor (LIF), MCSF, SDF1, angiopoietin 1, activin A
3) Obstruction of fibrosis: stem cell growth factor (HGF), bFGF, ADM
4) Obstruction of paracrine effect: the immune-mediated effects of VEGF, HGF, IGF1, TGFβ, bFGF, GM CSF, activin A and platelet 1 mainly include 5) -8)
5) T cell and B cell inhibition: leukocyte antigens G5, HGF, iNOS, IDO, PGE2, bFGF, TGFβ
6) Differentiation and proliferation effects were achieved through TGFβ discovery of controlled T cells
7) Inhibit NK cells through IDO, PGE2 and TGFβ secretion
8) Inhibit dendritic cell maturation through secretion of PGE2
