✦ Synopsis
Fragments of iris ring, spleen, kidney, tail, tail blastema, tentacle, tentacle blastema, and spinal cord were implanted between the outer and the inner cornea in normal eyes of Xenopus laeuis tadpoles at stage 50 (according to Nieuwkoop and Faber, '56).
Results show that tail blastema, tentacle blastema, and spinal cord can induce varying degrees of lens-forming transformations in the outer cornea, while the iris ring, spleen, kidney, tail, and tentacle do not produce any significant response from the cornea, thus demonstrating that the lens-inducing capacity is not widely distributed in the larval tissues of Xenopus.
The causes of the different degrees of lens-inducing capacity in the various larval tissues are discussed.
