A possible role for the vascular membrane in retinal regeneration in Rana catesbienna tadpoles.

We have studied the process of retinal regeneration in Rana catesbienna tadpoles using a recently developed monoclonal antibody (2D3) directed against frog neurons and germinitive neuroepithelium. We have found that, following retinal degeneration induced by devascularization, new retina is generated in the posterior eye from transdifferentiating pigment epithelial ( RPE) cells and in the anterior eye from increased proliferation at the normal growth zone in the ora serrata. This demonstrates that the anuran retina regenerates in a manner similar to that observed previously in urodeles. In addition, the use of MAb-2D3 has allowed us to study the process of RPE transdifferentiation more accurately than was previously possible, and consequently we have found a high degree of association of migratory pigment cells with the retinal vascular membrane at the time of the initial RPE transdifferentiation to retinal neuroblasts.[1]
