Stroma corneal regeneration

Nevertheless, the stroma might also have some ability to regenerate the cornea. That is what the Thill and his assistant study [7] seems to demonstrate with the highlighting of a new population of repairing stem cells located inside the adult human corneal stroma. These cells might evolve toward the monocyte-macrophage specie or toward the ti broblast specie (keratocytes). 

Bowman s layer is a thin homogeneous sheet of acellular randomly arranged collagen fibers lying between the epithelial basement membrane and the stroma. Bowman s layer is relatively tough and provides substantial resistance to corneal injury or infection. Because it cannot regenerate, scarring results when it is disrupted.
