Which layers of the cornea can regenerate? (Choose 2)

The correct answer indicates that the epithelium and Descemet's membrane are the layers of the cornea that can regenerate.

The corneal epithelium is a rapidly renewing layer composed of stratified squamous cells. This layer undergoes continuous turnover and can regenerate effectively after injury due to the presence of basal cells, which divide and migrate to replace sloughed-off cells. This regenerative capability is vital for maintaining the cornea's protective barrier and its transparency.

Descemet's membrane, which is a thin layer of connective tissue, also possesses some regenerative capabilities. While it does not regenerate as quickly or as readily as the epithelium, it can undergo repair after damage, particularly with the help of the endothelial cells that reside just beneath it. Endothelial cells can produce components of Descemet's membrane, allowing for some recovery from injury.

Other layers of the cornea, such as Bowman's layer, do not have the ability to regenerate effectively after injury. Bowman's layer is a tough, acellular layer that acts as a protective barrier, but if it is damaged, it does not heal through regeneration; the healing process may result in scarring or disruption of the normal architecture. The endothelium,
