Reptiles have placodes too. But in a reptile embryo each placode switches on genes that cause only the skin cells on the back edge of the placode to grow, eventually forming scales.
爬行动物身上同样存在基板,但在胚胎阶段时,它们只会触发基板后延的皮肤细胞基因进行增殖,并最终形成鳞片。
In the bird embryo these bristles erupt from tiny patches of skin cells called placodes. A ring of fast-growing cells on the top of the placode builds a cylindrical wall that becomes a bristle.
鸟胚中的刚毛结构来自于被称为基板(placode)的微小皮肤细胞结构,基板顶端快速增殖的细胞环形成了刚毛的圆柱井结构。
