Figure 6From: Comparison of upstream regulators in human ex vivo cultured cornea limbal epithelial stem cells and differentiated corneal epithelial cellsSignificantly expressed angiogenesis-related genes in LESCs. Angiogenesis is a complex process mediated by MMPs, proteolytic enzymes and ECM proteins (A). Cytokines and growth factors are important players of angiogenesis with endothelial cell activation and EPC/stem cell differentiation (B). Most of the angiogenic molecules belong to these molecule types (C and D).Back to article page
