Which tissue contributes to scleral formation?

Explanation:
The sclera forms from neural crest–derived mesenchyme that migrates into the developing eye and differentiates into fibroblasts producing collagen to create the dense scleral stroma. Endoderm forms internal linings such as the gut and related structures, not the scleral connective tissue. Ectoderm gives rise to external surfaces and neural tissue, but the sclera proper comes from neural crest–derived mesenchyme (the cells that populate ocular connective tissues). Mesoderm contributes to other ocular structures, but the scleral stroma is best explained by neural crest–derived mesenchymal origin.
