对于要再生远端元素的附属物，人们认为残肢必须包含完整的周向位置信息。我们已经证明，这一规则对果蝇雄性前腿成像盘中的鞑靼再生没有约束力。远端转化并不局限于包含完整近端节段的片段，也可以观察到具有小的甚至实质性缺陷的片段，这些片段在其近端节段没有再生。
For an appendage to regenerate distal elements, it has been thought that the stump must contain a full set of circumferential positional information. We have shown that this rule is not binding for tarsus regeneration in the male foreleg imaginal disc ofDrosophila melanogaster. Distal transformation was not restricted to fragments containing complete proximal segments, but was also observed in pieces with small or even substantial deficiencies that were not regenerated in their proximal segments.
