Limbal explants and 3D cell outgrowth stained for additional stemness and proliferation markers.

Limbal explant and proximal outgrowing cells stained for p63α and/or Vim (A, B, C), and distal growing cells forming 3D structures being stained for proliferation marker Ki-67 (D) (Magnification: 40x, White bars represent limbal explants and proximal outgrowths, while black bar demonstrate data from distal growing 3D cell sheets. Data are expressed as mean ± SEM.
