In the male foreleg disk ofDrosophila melanogaster the cells capable of transdetermination are clustered in a specific region within the upper half of the disk. Cells outside this region cannot transdetermine under any of the experimental conditions thus far applied.Transdetermination occurs when cells capable of transdetermination are stimulated to a certain extent of additional proliferation. This can be achieved either by exposing these cells at a wound surface of an intact fragment, or by dissociation.
在黑腹果蝇的雄性前腿盘区，能够进行转决定的细胞聚集在盘区上半部分的一个特定区域内。该区域外的细胞在迄今为止所应用的任何实验条件下都不能进行转决定。当能够进行转决定的细胞被刺激到一定程度的额外增殖时，转决定就会发生。这可以通过将这些细胞暴露在完整片段的伤口表面或者通过解离来实现。
