Figure 2 Examples of lens regeneration in axolotl larvae. A: A regenerating lens 2 days after lentectomy (lentectomy was performed at
stage 44 + 2 days). Note that the lens is attached to the iris and shows the characteristic structure of the lens epithelium at the anterior (arrow)
and differentiated lens fibers at the posterior region (arrowhead). B: A section through the head of an un-operated animal at the same stage as
in A (in this case stage 44 + 4 days) to compare the degree of lens differentiation. C: A regenerated lens 7 days after lentectomy (lentectomy
was performed at stage 44 + 3 days). Note an almost complete differentiation of lens. D: A section through the head of an un-operated animal
at the same stage as in C (in this case stage 44 + 10 days) to compare the degree of lens differentiation. H & E staining.
