When the diploid histoblasts, the precursors of adult abdominal epidermal cells, of the larva of Drosophila are deleted by gamma-radiation, the polytene larval epidermal cells survive metamorphosis and secrete cuticle and cuticular outgrowths. A comparison of the morphology of the cuticle secreted by the larval epidermal cells in the different regions of the abdominal segments to that secreted by the histoblasts of the unirradiated animal suggests that the former contain the blueprint for the pattern of landscape of the adult abdominal cuticle and possibly could provide this information to the dividing and spreading histoblasts during the normal ontogeny of the fly.
当果蝇幼虫的二倍体组织母细胞（成体腹部表皮细胞的前体）被γ射线照射消除后，多线幼虫表皮细胞在变态过程中存活下来，并分泌角质层和角质层衍生物。将腹部体节不同区域的幼虫表皮细胞分泌的角质层形态与未受照射动物的组织母细胞分泌的角质层形态进行比较，结果表明，前者包含成体腹部角质层景观模式的蓝图，并且在果蝇正常个体发育过程中可能会将此信息提供给正在分裂和扩散的组织母细胞。
