Which tissue is the embryologic origin of the corneal stroma?

Explanation:
Neural crest–derived mesenchyme. During eye development, neural crest cells migrate into the developing cornea as periocular mesenchyme and differentiate into keratocytes that populate the corneal stroma, laying down the organized collagen matrix essential for the cornea’s transparency. The corneal epithelium, in contrast, comes from surface ectoderm, and the endothelium also has neural crest origins, but the stroma specifically is formed from neural crest–derived mesenchyme. Neuroectoderm gives rise to neural tissues like the retina, and mesoderm contributes other tissues, not the corneal stroma.
