solid lens vesicle

Term ID

ZFA:0001679

Synonyms

• immature lens
• lens mass
• lens vesicle
• presumptive lens

Definition

Portion of tissue that gives rise to the lens. The lens of the zebrafish forms by delamination of lens placodal cells and not through invagination. This results in a solid spherical mass as opposed to a hollow lens vesicle. Detachment of the solid lens vesicle of zebrafish at 24-26 hpf is accomplished in part by apoptosis, similar to mammals.
