Figure 10. Expression of stem/progenitor cells (integrin β1, ABCG2) and differentiation-associated markers (K3/12) in ex vivo–expanded human LECs. Immunofluorescence staining shows positive expression of cytokeratin; (B), K3/12, (E) integrin β1, (H) ABCG2 on PCL nanofibers similar to coverslip (control; A) K3/12, (D) integrin β1, (G) ABCG2 and HAM (H) K3/12 (F), integrin β1, (I) ABCG2.
