In experiment #5, treatment of cis and trans retinyl palmitate resulted in a 93% survival rate (13 out of 14 survived, excluding tadpoles that were upgraded to experiment #4). Six out of thirteen tadpoles (including controls) developed abnormal tails. Additionally, as in experiment #2, faster regeneration of the control animals’ tails than the experimentals’ tails was observed. In addition, one of the experimental tadpoles resulted in a split of the regenerating tail tip [Fig.1, D]. All tadpoles survived in the extension of experiment #5, in which all tadpole tails were reamputated at the same half way midpoint. Two out of the four experimental displayed abnormal tails. All legs formed normally, however. Furthermore, re-amputation of tails showed no additional irritation or unique abnormality. The control tail regenerated faster than experimental tails. In experiment #8, all animals except one died within the first week. To test why this happened, four control bowls were added to the experiment. After returning in three days, we found that all except for one have died. Our conclusion was that this was due to the concentration of the anesthetic since the one animal that survived was not anesthetized. The one remaining tadpole from experiment #8 regenerated an abnormal tail, almost limb-like. Pigment was fully restored and the tail regenerated so that the cutting line was no longer visible. In experiment #9, only two tadpoles survived. As in experiment #8, these animals were not feeding as well as animals in previous experiments. However, both animals regenerated abnormal tails. Pigment was fully restored to one of the remaining animals, while the other died before restoring pigment. In experiment #11, only two of the eight died within the first couple of weeks. Controls regenerated normal tails, while experimentals regenerated abnormally. Pigment also restored completely. All sorts of shapes of tails were formed. Experiment #12 tadpoles had the best survival rate. All of the tadpoles survived long enough to be followed. All experimentals regenerated abnormal tails, some more irregular than others. The two controls regenerated what appeared like normal tails. All animals fully restored pigment. Interestingly, the animals in the two bowls in which thyroxine was added regenerated much quicker. The thyroxine controls regenerated normal tails in contrast to the unusual tails of the experimental tadpoles. All survivors of experiments #8, #9, #11, and #12 that had abnormal tails were whole-body stained. We found several interesting results that demonstrated possible limb induction. Figure 2 shows interesting whole body stained tadpoles. Interesting tadpole tails had their tips removed and sectioned. Sections exhibited interesting details. In experiment #9, muscle, epithelium, notochord, and a flattened nerve tube were found [Fig. 3, A]. In experiment #11, mesenchyme, pigment, epithelium, and possible notochord were visible [Fig. 3, B]. A good sign of possible limb induction was found in experiment #12. Neural tube, notochord, pigment, epithelium, mesenchyme cells, skeletal muscle, and nuclei were observable [Fig. 3, C-D]. Meeting of Minds 2006 144
