Which animal is used as a model to study 'lens regeneration', where the iris cells dedifferentiate and transform into a new lens?
Show answer and explanation
Correct answer: Red-spotted newt
Newts (and some other salamanders) exhibit Wolffian regeneration. After lens removal, pigmented epithelial cells of the dorsal iris lose their pigment, proliferate, and transdifferentiate into a new functional crystalline lens.
