Lens placode

From Wikipedia, the free encyclopedia

Lens placode

Transverse section of head of chick embryo of fifty-two hours’ incubation.
Latin	placoda lentis
Precursor	surface ectoderm
Gives rise to	lens
Code	TE E5.16.3.1.0.0.13

The Lens placode is a thickened portion of ectoderm which serves as the precursor to the lens.

SOX2 and Pou2f1 are involved in its development.^[1]
