细胞估计其在体内位置的机制

细胞如何估计它们在体内的位置的问题与发育中的有机体的细胞为什么会分化的问题密切相关。生物体内的所有细胞都具有相同的遗传设备。因此，那些（根据其位置）必须形成特定器官的人需要一些其他人无法获得的特殊信息。我们现在正在调查的机制，使用不同的表皮结构在腹部节的蛹大蜡螟。
THE question of how cells estimate their location within the body is closely related to that of why cells of a developing organism become differentiated. All cells within an organism have the same genetic equipment. Therefore, those which (according to their location) have to form a particular organ need some special information which others do not get. We are now investigating the mechanism involved, using distinct cuticular structures in the abdominal segments of the pupa of Galleria mellonella.
