From: Sphere-forming cells from peripheral cornea demonstrate the ability to repopulate the ocular surface
Immunostaining of peripheral corneal spheres reveals expression of putative stem cell and niche markers. Spheres were imaged at 60× objective magnification by confocal microscopy and labelled with antibodies (green signal) for ∆Np63α a, ABCG2 b, ABCB5 c, notch 1 d, laminin e and keratocan f.
