Eye development Flashcards
1
Q
what are the 3 main components of the vertebrate eye
A
the retina, the lens and the cornea
2
Q
from what tissue is each of the main eye components derived
A
the retina is derived from the neural tube
the lens is derived from the optic placode
The cornea is derived from the epidermis
3
Q
what is pax6
A
pax6 is the transcription factor involved in lens development
4
Q
when does the lens develop in vertebrates
A
the lens starts to develop only when the optic vesicle is in close proximity to the surface ectoderm
pax6 expression in both the SE and OV is required for lens formation
5
Q
what is crytsallin
A
crystallin is the marker used to show Pax6 expression.
Crystallin will be expressed in areas where the lens will form
