Abstract:
The newt is one of the few organisms that is able to undergo lens regeneration as an adult. This review will examine the signaling pathways that are involved in this amazing phenomenon. In addition to outlining the current research involved in elucidating the key signaling molecules in lens regeneration, we will also highlight some of the similarities and differences between lens regeneration and development.
Insights
Newts can regenerate their eye lenses as adults, a rare ability. This review explores the signaling pathways and molecules crucial for newt lens regeneration, comparing it to lens development.
Area of Science:
- Regenerative medicine
- Developmental biology
- Ophthalmology
Background:
- Adult newts possess a remarkable capacity for ocular lens regeneration.
