Fig. 3. Regulatory interactions during lens formation in the head surface
ectoderm and lens. (A) Schematic depicting selected transcription
factors important for lens formation that are expressed in the mouse head
surface ectoderm. These interactions help specify the activation of
Foxe3 in the lens placode. (B) Roles of Foxe3 in the
development and differentiation of the lens (orange). Feedback loops are not
depicted here and arrows between genes do not necessarily imply direct
regulatory interactions.
