“…Growth factors secreted by ADSC transplantation (i.e., VEGF, FGF2, TGF-β, HGF, platelet-derived growth factor (PDGF), keratinocyte growth factor (KGF), fibronectin, and collagen I and increased expression of VEGFR-3) promote lymphatic regeneration [24,26,59,61]. Factors associated with lymphangiogenesis and fibrosis include: Tgfb1, suppression of which improves both fibrosis and lymphangiogenesis [18,62]; tumor necrosis factor (TNF)-α and interleukin (IL)-1 [48]; and neutrophils that increase lymphatic vessel density by increasing the number of VEGF-A/VEGFR-2 complexes and releasing VEGF-D [14].…”
