Efficacy of Topical Mesenchymal Stem Cell Therapy in the Treatment of Experimental Dry Eye Syndrome Model
BrdU labeled MSCs were shown to infiltrate the meibomian glands and conjunctival epithelium. (a) Meibomian gland infiltration of BrdU labeled MSCs. Cells with BrdU+ stained nucleus (red arrows). Spread of BrdU stained areas to the cytoplasm of some cells (yellow arrow). (b) BrdU+ cells in the conjunctival epithelium (red arrow) (Leica HMLB45: Germany, 2000; magnification: ×400).
