These induced blastemas never progressed to the later stages of regeneration to form a new limb, however.One more ingredient was needed. 然而这些诱导形成的芽基却无法继续进展到后期而长出新脚，显然我们还缺少了其他要素。
They found that salamander regeneration begins when a clump of cells called a blastema forms at the tip of a lost limb. 他们发现，蝾螈再生是从一团被称为芽基的细胞在断肢顶端形成的时候开始的。
But if we carefully deviated a nerve to the wound site, we could induce those fibroblasts to form a blastema instead. 但如果我们小心地将一条神经转向受伤的地方，我们就可诱导那些纤维母细胞形成芽基。
Tanaka next hopes to decipher the genetic instructions governing blastema formation. 塔纳卡接下来希望破译控制芽基形成的基因指令。
Blastema in WT consists of sheets of densely packed small blue cells with hyperchromatic nuclei, little cytoplasm and conspicuous mitotic actiity. 后肾胚芽由密集排列的片状小蓝色的细胞构成，核染色质粗糙，胞浆稀少，有丝分裂像明显。
